How to choose the precise temperature for titanium alloy forging

Titanium alloy forging temperature how much appropriate, titanium alloy as an important engineering materials, because of its excellent mechanical properties and good corrosion resistance, in the aerospace, medical equipment, chemical industry and other fields have been widely used. In the processing of titanium alloy, forging is a vital process, and the choice of forging temperature is directly related to the performance of titanium alloy and the quality of the finished product, today I will take you to understand the titanium alloy forging temperature how much suitable.
The forging temperature of titanium alloy is usually affected by its alloy composition, organizational structure and desired properties. Generally speaking, the forging temperature range of titanium alloys is relatively wide, but the selection of the specific temperature needs to be determined according to the type of alloy and forging requirements. Too high a forging temperature may lead to titanium alloy grain size, reducing its mechanical properties; while too low a forging temperature may lead to titanium alloy plasticity reduction, difficult to form. Therefore, determining the appropriate forging temperature is a key link in the titanium alloy forging process.

When selecting the forging temperature of titanium alloy, the first thing to consider is the phase change point of the alloy. The phase change point of titanium alloy is the temperature point where the organization structure changes significantly, which can usually be determined by thermal analysis and other methods. Forging in the vicinity of the phase change point is conducive to obtaining fine grain organization, improve the mechanical properties of titanium alloys. In addition, the forging temperature should also take into account the plastic deformation capacity and work hardening degree of titanium alloy. In the plastic deformation capacity is better, the degree of work hardening is lower under the temperature of forging, is conducive to reducing energy consumption, improve production efficiency.
In addition to the factors of the alloy itself, the performance of the forging equipment, mold design and forging process parameters will also have an impact on the choice of forging temperature. Therefore, in actual operation, it is necessary to make comprehensive consideration according to the specific situation, and determine the best forging temperature through testing and optimization.
The forging temperature of titanium alloy varies according to its type and performance requirements:
α-β type titanium alloy. The forging temperature is generally between 900℃ and 950℃.
Pure titanium and α-type titanium alloys. Lower forging temperatures, typically between 700°C and 750°C.
Beta titanium alloys. The forging temperature is usually between 800°C and 1050°C.
The forging temperature of titanium alloy should be changed according to the type of titanium alloy, performance requirements and process conditions, etc. The forging temperature of titanium alloy is usually between 700℃ and 1050℃.
