Ring-Rolling Process for Manufacturing Ti-6Al-4V Plane and Profiled Ring-Products
Manufacturing processes of Ti-6Al-4V plane and profiled ring-products were investigated with three-dimensional FEM simulation and experimental analyses. FEM simulation for the ring-rolling process was used to calculate the state variables such as strain, strain rate and temperature. To induce the uniform deformation of the profile ring and reduce the applied load, the final blank was prepared by two-step processes. The mechanical properties of Ti-6Al-4V alloy ring products made in this work were investigated with tensile and impact tests, and compared with the specification(AMS-T-81915).
