Abstract

The mechanical and physical properties of materials are closely related to their texture. The influence of hydrogen on the evolution of recrystallization textures (R-cube, {111}[110], {111}[112], and {112}[1-10]) in a body-centered cubic metal was studied. Hydrogen at high temperatures promotes the evolution of R-cube and {112}[1-10] textures while hindering the evolution of {111}[110] and {111}[112] textures. The influence of hydrogen on recrystallization texture evolution differs between the nucleation and grain growth stages. Hydrogen promotes the evolution of {111}[110] and {111}[112] textures during both the nucleation and grain growth stages. For the R-cube and {112}[1-10] textures, hydrogen facilitates their evolution during the nucleation stage but hinders it during the grain growth stage. The mechanisms driving texture evolution during recrystallization nucleation and grain growth are suggested to be hydrogen-enhanced subgrain boundary migration (HESBM) and hydrogen-enhanced specific crystal plane rotation (HECPR), respectively.

氢对纯铁再结晶织构演化的影响

材料的机械性能和物理性能与其织构密切相关。研究了氢对体心立方金属再结晶织构（R-cube、{111}[110]、{111}[112]和{112}[1-10]）演化的影响。高温下的氢促进了R-cube和{112}[1-10]织构的演化，而阻碍了{111}[110]和{111}[112]织构的演化。氢对再结晶织构演化的影响在成核和晶粒长大阶段有所不同。在成核和晶粒长大阶段，氢都促进了{111}[110]和{111}[112]织构的演化。对于R-cube和{112}[1-10]织构，氢在成核阶段促进它们的演化，而在晶粒长大阶段阻碍它们的演化。在再结晶成核和晶粒长大过程中，驱动织构演化的机制分别是氢增强亚晶界迁移（HESBM）和氢增强特定晶面旋转（HECPR）。
