초미세립 순-타이타늄의 미세조직과 인장물성
Microstructure and Tensile Properties of Ultrafine Grain Pure-Titanium
초록
A study was made to investigate microstructural evolution and mechanical properties of ultra-fine grained (UFG) pure-Ti produced by equal channel angular (ECA) pressings. The deformed structures were analyzed by finite element method and transmission electron microscopy with the increment of straining. After 4 isothermal ECA pressings, initial coarse grains (
