Ti-10V-2Fe-3Al 합금의 열간성형성에 미치는 초기미세조직의 영향
Effect of Initial Microstructures on Hot Formability of Ti-10V-2Fe-3Al Alloy
초록
A study has been made to investigate how the fomability of Ti-10V-2Fe-3Al alloy is related to the initial microstructure and process variables such as temperature and strain rate. It has been found that the deformation resistance at high temperature is increased with the increase in the thickness of grain boundary a (GB)a and/or acicular a phase and however the effect of a morphology on the hot formability is considered insignificant due to the breakage of GB a and/or acicular a into several equiaxed a particles
