Titanium forgings isothermal forging process

In recent years, titanium alloy has rapidly developed into a new key structural material with strong vitality because of its high specific strength, excellent corrosion resistance, good biocompatibility and other advantages, and has been widely used in aerospace, military industry, petrochemical industry and medical and health fields. Because of the difficulty of cold deformation of titanium alloy, therefore, in the use of titanium and titanium alloy semi-finished or finished products, often need to titanium ingot first through hot processing method deformation to a variety of blanks and forgings, forging and pressing processing is the most commonly used means. In addition, the heat treatment of titanium alloy has no decisive effect on its microstructure. Therefore, titanium forging process can not only make the forgings close to the finished product in shape and size, but also play an important role in improving the gold structure and performance of titanium table. The following titanium forgings manufacturer introduces the isothermal forging process method of titanium forgings:

Isothermal forging is an advanced processing technology, which can make titanium alloy and other difficult-to-deform materials at relatively constant deformation temperature, with very low deformation rate, to get complex shape of precision forgings. The forgings formed by this process need only a small amount of mechanical processing can be assembled and used, the material utilization rate is high, and because of good process controllability, uniform deformation, the microstructure and properties of the forgings are more stable and uniform, batch production of titanium forgings, has significant economic benefits. Compared with conventional forging, isothermal forging titanium alloy has the following advantages:

① Isothermal forging can achieve precision forging, forging load is small, die wear is small.

② It is easy to control the processing parameters, uniform microstructure can be obtained, coarse grains are less, 20% ~ 30% spherical A-phase can be obtained, so its mechanical properties are equal to or better than conventional forging products.

③ Isothermal forging process can also reduce or eliminate the influence of die cooling and material strain hardening, significantly reduce the deformation resistance and improve the formability of billet. Therefore, isothermal forging process has become an important development direction of titanium alloy forgings at home and abroad.

At present, isothermal forging hardware is quite mature in developed countries, such as temperature controller, constant strain rate controller and computer feedback system.
