首先介绍了一种新的应变诱导熔体激活方法，即以等通道角挤压（ECAE）作为应变诱导步骤，用半固态等温处理完成熔体激活步骤，从而制备出平均晶粒尺寸为5 gm的球状细晶半固态坯料。与普通SIMA相比，采用新型SIMA制备的半固态坯料加工的半固态卫星角架部件具有更高的室温和393 K高温力学性能。(c) 2006爱思唯尔公司版权所有。
A new method called new strain induced and melt activated (new SIMA) is introduced firstly through using equal channel angular extrusion (ECAE) as strain induced step in SIMA and completing melt activated step by semi-solid isothermal treatment, by which semi-solid billet with fine spheroidal grains with average grain size of 5 gm can be prepared. Comparing with common SIMA, semi-solid processed satellite angle frame components using semi-solid billet prepared by new SIMA have higher room temperature and 393 K high temperature mechanical properties.
