Abstract

A low-cost super-plastic titanic alloy consists of Al 3.0-6.0wt%, V 2.0-4.0wt%, Mo 1.0-3.0wt%, iron 0.5-2.0wt%, Cr 0.5-2.0wt%. It achieves low cost and easy plastic deformation.

Description

technical field [0001] A low-cost superplastic titanium alloy relates to a near-beta low-cost superplastic titanium alloy. Background technique [0002] Titanium alloy has low density, high specific strength, and good corrosion resistance. It is an ideal structural material and plays an important role in military fields such as aircraft and ships and civilian fields such as chemical and pharmaceutical industries. However, the processing of titanium alloys is difficult, which makes the cost of titanium alloy products relatively high, thus limiting the wide application of titanium alloys. The development of superplastic titanium alloys enables titanium alloys to be net-shaped through superplastic forming diffusion connection technology materials at superplastic temperatures, thereby reducing processing procedures, improving material utilization, and manufacturing structural parts with complex shapes at one time. While the cost of alloy manufacturing is reduced, the weight is ...
