Modes of grain growth and mechanism of dislocation reaction under applied biaxial strain: Atomistic and continuum modelingYing-Jun Gao1,Qian-Qian Deng1,Zhe-yuan Liu1,Zong-Ji Huang1,Yi-Xuan Li1,Zhi... of the new deformed grain. The research is shown that due to the nucleation of different modes the mechanism of the grain growth by means of the sub-GB migration is different, and therefore, the grain......
