Titanium forging is a forming processing method that applies external force to titanium metal blanks (excluding plates) to cause plastic deformation, change size, shape and improve performance, and is used to manufacture mechanical parts, workpieces, tools or blanks. In addition, according to the way the slider moves, there are vertical and horizontal movements of the slider (for forging of slender parts, lubrication and cooling, and forging of parts for high-speed production), and the compensation device can increase the movement in other directions.
Titanium forging is a set of specialized manufacturing processes used to create components from titanium alloys. The process that is ultimately used depends on the metallurgical properties of the starting material, plus the specific structure the forger is looking to create. Some of the processes include:
Open die forging: Blank titanium material is deformed and pressed into shape in the cavity between two molds. These molds do not completely encapsulate the material but instead provide a narrow gap through which excess material can flow out. When in the cavity, the titanium is repeatedly stamped until the desired shape is achieved.
Closed die forging: Also known as impression die forging, this method uses compression under high pressure to shape a heated titanium blank. The blank is covered either in full or in part by the dies, which move toward each other from top to bottom to achieve the required form.
Free forging: Small and/or simple orders may be accomplished with free forging, a titanium forging method that is performed between two flat dies without an inner cavity. It is a relatively inexpensive and flexible method, but due to high labor requirements, it's not the most common way to forge large amounts of titanium metal.
Isothermal forging: A process by which the starting material and the die are heated to an equal and highly controlled temperature to achieve high deformation rates with minimal pressure.
Properties of Titanium Forging
To forge titanium forging properly, one must know the metallurgical properties, and what happens to the material when it is heated in preparation for the forging process at a microstructural level.
There are two distinctive phases associated with titanium forging and titanium forging alloys that occur in the material during the heating process. These phases are known as the alpha and beta phases, and it is crucial to understand these phases well in order to properly forge titanium forging.
Alpha (α) Phase
The alpha phase is a low temperature allotriomorph with hexagonal close packed structure. The alpha phase is present from room temperature to 1625 °F. Alpha grade titanium forging possesses the highest resistance to corrosion in comparison to other titanium forging grades.
Beta (β) Phase
Titanium forging transform into the high temperature allotriomorph namely the body centered cubic beta phase at 1625 °F, and remains as a beta up to the melting point of 3038 °F. This phase makes titanium forging ideal for forging applications, as well as heat treating, and welding, while still maintaining incredible strength and high corrosion resistance.
titanium forging can easily be combined with other metals to create stronger alloys, resulting in three grade types of titanium forging alloys. The three grades of titanium forging alloys are: alpha alloys, alpha-beta alloys, and beta alloys.
Alpha alloys essentially remain in the alpha phase, with their resistance to creep typically reaching up to 1,000 °F. Alpha stabilizers that make up titanium forging alpha alloys are aluminum, oxygen, and nitrogen carbon.
Alpha-beta alloys combine both alpha and transformed beta microstructures at room temperature. These alloys are heat treatable to high strengths and contain neutral elements such as tin and zirconium. A well-known alpha-beta grade alloy is Ti-6AL4V.
Beta alloys are titanium forging alloys that contain a sufficient percentage of other alloys to maintain the beta phase at room temperature, and can be heat treated to immensely high strengths. This grade of titanium forging alloys contains beta stabilizers, such as vanadium, molybdenum, niobium, and tantalum.
Straightening of Titanium Forgings
Because of the low elastic modulus and relatively high strength of titanium alloys, forgings are difficult to cold straighten either by coining or reverse bending. Such operations are usually done at temperatures between 380-530°C. At times it is necessary to maintain a straightening load on a forging for several seconds. This technique is especially useful for removing large warpages.
Temperature of Forged Titanium Forgings
Forging is a method of shaping whereby the metal is deformed by the action of repeated blows. Open die and closed die are the two basic methods of forging titanium. Here the force is applied by a hammer, with gravitational force being utilized either alone or in combination with steam pressure, air pressure, or some supplementary force. The forging operation must be carried out with the metal kept at an elevated temperature to facilitate the flow of the titanium.
Open die forging is usually employed to rough-shape the material. To accomplish this, flat dies V-dies, and swage die are used. Flat dies are primarily used to forge flat material or to forge rounds into polygonal shapes. V-dies may also accomplish this on round or square stock. Swage or curved dies are used to reduce the diameter of round stock or to produce rounds from polygonal stock.
Titanium has been successfully forged by the open die method using conventional equipment designed for steel, but with lower temperatures and increased pressures. The lower temperature is required in the forging of titanium since this will, first, limit the resultant surface contamination and, second, prevent excessive grain growth, both of which reduce ductility in the forged part. Because of the lower temperature, it becomes necessary to use higher pressures to deform the metal.
Forging temperatures usually range between 1450°F (790°C) and 1950°F (1065°C). Lower temperatures up to 1650°F (900°C) are applicable to the unalloyed titanium, while higher temperatures are used with alloyed titanium. Lower temperatures than those stated can be used if the equipment is capable of delivering the force necessary to deform the metal.
It has been recommended that soaking temperatures are around 1200 to 1300°F (650 to 700°C) and that the material be heated to the forging temperature just prior to the operation. Forging can be carried out as the temperature drops. To obtain good ductility, it has been found preferable to finish-forge at a temperature not below 1550°F (840°C).
Closed die forging differs from open die in that a finished shape is produced. The metal is forced into a preshaped die so that the exact desired contours are obtained. In closed die forging, temperatures and pressures for heavy parts are comparable to those employed for open die forging. Light gauge material is formed at 800 to 1000°F (425 to 540°C) with slightly lower pressures required and a slower deformation rate.
Forgings refer to products manufactured by the process of shaping metal utilizing compressive forces. The compressive forces used are generally delivered via pressing, pounding, or squeezing under great pressure. Although there are many different kinds of forging processes available, they can be grouped into three main classes:
Drawn out: Length increases, cross-section
Upset: Length decreases, cross-section increases decreases
Squeezed in closed compression dies: Produces multidirectional flow
Forging produces pieces that are stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, the internal grain deforms to follow the general shape of the part. This results in a grain that is continuous throughout the part, resulting in its high strength characteristics. Forgings are broadly classified as either cold, warm or hot forgings, according to the temperature at which the processing is performed. Iron and steel are nearly always hot forged, which prevents the work hardening that would result from cold forging. Work hardening increases the difficulty of performing secondary machining operations on the metal pieces. When work hardening is desired, other methods of hardening, most notably heat treating, may be applied to the piece. Alloys such as aluminum and titanium that are amenable to precipitation hardening can be hot forged, followed by hardening. Because of their high strength, forgings are almost always used where reliability and human safety are critical such as in the aerospace, automotive, ship building, oil drilling, engine and petrochemical industries.
Forging Enhances the Strength of Titanium Forgings
Titanium forgings produce strong, low-density parts similar to carbon steel forging or stainless steel forgings, but about 40% lighter. Titanium forgings offer high resistance to corrosion by salt water, along with a broad range of acids, alkalis, natural waters and industrial chemicals. Titanium forgings come in a variety of shapes, such as rings, cylinders, bars, blocks, discs, sleeves, hubs, flanges, as well as any number of more complex custom shapes for particular applications. Titanium forgings work effectively in environments reaching up to 1000 degrees Fahrenheit.
Because of their excellent strength-to-weight ratio, titanium alloy forgings are used in applications such as engine components and structural components for aircraft, ship components, and valves and fittings for the transportation and chemical industries, where corrosion resistance, optimal strength and low weight are needed.
The titanium forging process gives the metal a sophisticated structure that enhances its strength. Most often titanium forgings are created by heating a preformed piece of titanium or titanium alloy and then using a large forging hammer or press that forces the workpiece to take the shape of the die(s). Unlike in casting, the metal is not melted or poured; instead the forging process uses intense pressure to cause the metal to flow into the desired shape.
The process often proceeds gradually through numerous strikes, requiring an operator to move the workpiece through a series of impression cavities. A variety of equipment can be used to forge titanium. Drop forge equipment utilizes a massive drop-hammer that falls from above on the workpiece as it lies on a stationary anvil. In counterblow machines, both the hammer and the anvil move horizontally to impact the workpiece that is held between them.

Q: What are the grades of titanium forgings?
6-2-4-2: Prized for its excellent creep resistance and strength at elevated temperatures, 6-2-4-2 titanium is utilized in components where high heat and stress are present.
6-2-4-6: Similar to 6-2-4-2 titanium, but with improved toughness and ductility.
3-2.5: Known for exceptional weldability and corrosion resistance, 3-2.5 alloy is often used in the medical industry for implants.
Q: Can you forge titanium at any temperature?
Hot forging is more common than cold forging, though the latter can be cheaper and more environmentally friendly. Notably, lower temperatures (below 1650 degrees Fahrenheit) are only suitable for non-alloyed titanium, while higher temperatures are a requirement for alloyed titanium.
It's not just the temperature of the titanium itself that is essential during forging. The dies' temperature must also be controlled since excessive heat loss or variations in heat will lead to defective parts.
The importance of temperature in the titanium forging process is primarily related to the metal's structural elements at various heat levels. By forging with the correct heat levels of starting material and dies, the forger can create a more robust and reliable end product—one that is structurally suitable for the job at hand.

Q: What is the standard for titanium forging?
Q: How to heat process titanium forgings?
All forging furnace atmospheres contain free or combined oxygen, and some absorption of this element inevitably occurs. In addition to visible scaling, diffusion of oxygen results in hardening of a relatively shallow underlying layer. The effect of nitrogen is not usually significant at preheating temperatures. Subsequent operations such as machining will remove the hardened surface layer, and the final product will have hardness similar to forging stock.
