Titanium alloy bars, TC4 titanium alloy bars, are typically completed in three stages from ingot to finished bar.

1. Open Die Forging: The initial forging (open die) temperature is above the beta transformation point, at 150-250°C, where the plasticity of the casting structure is good. Initially, light and quick strikes should be applied to deform the ingot until the primary coarse crystal structure is broken. The degree of deformation must be maintained within the range of 20%-30%. The ingot is forged into the required cross-section and then cut into blanks of specified dimensions. After the casting structure is broken, plasticity increases. Recrystallization intensifies with increasing temperature, prolonged holding time, and grain refinement. To prevent the occurrence of recrystallization, the forging temperature must be gradually reduced as the grain refines, and the heating and holding time must be strictly controlled. 2. Multi-directional Repeated Upsetting and Drawing: This process starts forging at a temperature 80-120°C above the beta transformation point, alternating between 2-3 cycles of upsetting and drawing, while also alternating the axis and edges. This results in a very uniform recrystallized fine-grained structure with beta zone deformation characteristics across the entire blank cross-section. If the blank is rolled on a mill, this multi-directional upsetting and drawing may not be necessary. 3. Second Multi-directional Repeated Upsetting and Drawing: This is similar to the first multi-directional repeated upsetting and drawing, but the initial forging temperature depends on whether the semi-finished product after forging is a blank for the next process or a delivered product. If it is a blank for the next process, the initial forging temperature can be 30-50°C higher than the beta transformation temperature; if it is a delivered product, the initial forging temperature should be 20-40°C below the beta transformation temperature. Due to the low thermal conductivity of titanium, when upsetting or drawing the blank on free forging equipment, if the tool preheating temperature is too low, and the equipment's striking speed is low with a large degree of deformation, an X-shaped shear band often forms on the longitudinal or cross-section. This is especially true during non-isothermal upsetting on a hydraulic press. This occurs because the tool temperature is low, causing the surface layer of the metal blank to cool rapidly upon contact with the tool, and during deformation, the heat generated cannot conduct away quickly enough, resulting in a large temperature gradient from the surface to the center, leading to the formation of a strong flowing strain band in the metal. The greater the degree of deformation, the more pronounced the shear band becomes, ultimately leading to crack formation under opposing tensile stress. Therefore, when free forging titanium alloys, the striking speed should be faster, minimizing the contact time between the blank and the tool, and the tool should be preheated to a higher temperature, while also appropriately controlling the degree of deformation within the first stroke. During forging, the corners cool the fastest. Therefore, when drawing, the blank must be flipped multiple times, and the hammering force should be adjusted to avoid sharp angles. In hammer forging, light strikes should be applied in the initial stage, with a deformation degree not exceeding 5%-8%, and then the deformation amount can be gradually increased. Die forging is typically used to manufacture blanks that are close in shape and size to the finished product, followed by only heat treatment and cutting processing. The forging temperature and degree of deformation are fundamental factors determining the alloy's structure and performance. The heat treatment of titanium alloys differs from that of steel and does not play a decisive role in the alloy's structure. Therefore, the process specifications for the final step of titanium alloy die forging are particularly important.
