The Application of Isothermal Near Net-shape Forming Technology on Titanium Complicated Load-bearing Structures

摘要

The isothermal near net-shape forming technology is one of feasible approaches for forming titanium alloys and some other difficult deformation materials. Based on the current project researches and achievements, the application of isothermal near net-shape forming process was introduced, and the specific isothermal near net-shape forming technologies for small size,medium size and large size complicated structures were listed Forgings obtained by isothermal near net-shape forming exhibit good quality, reasonable streamline distribution along the forging, uniform and fine microstructure,and excellent mechanical properties. The size of the forgings was greatly refined, therefore a great precious raw material and machining hours were saved. However, the isothermal near netshape forming technology still faces further improvements to enlarge the engineering application scale.
