The preferential recrystalization phenomenon were analyzed via thermo-mechanical process (TMP). TMP results in a peculiar preferential recrystallization localized in Shell region of the HS-Ti owing to the preferential strain localization in shell during plastic deformation. This successfully led to superior properties. The study was successfully accomplished with 4 journal papers and 2 conferences.

通过热机械过程（TMP）分析了优先重结晶现象。 TMP导致在塑性变形过程中壳中的优先应变定位，因此在HS-TI的壳区域中定位在HS-TI的壳区域中的特殊优先重结晶。这成功导致了出色的特性。这项研究通过4篇期刊论文和2个会议成功完成。
