Microstructure evolution of processed Mg-Al-Zn alloy by equal channel angular extrusion in semi-solid isothermal treatment JIANG Ju-fu(姜巨福), LUO Shou-jing(罗守靖) School of Materials Science... extrusion(ECAE) in semi-solid isothermal treatment was investigated. The results show that with increasing semi-solid isothermal treatment temperature, the α phase solid grain size of processed Mg-Al......
of continuous heating and the isothermal annealing. The activation crystallization energy is determined by Kissinger method, i.e. Ec=3.02 eV. And the isothermal kinetics is modeled by the Johnson–Mehl–Avrami (JMA) equation, the Avrami exponents are calculated to be 3.35–4.3 for different isothermal temperatures, which implies the crystallization mechanism is a three-dimensional nucleation and growth......
