The dispersed primary silicon phase was also a strengthening phase. At high temperature the main reasons for the strength decrease and plasticity increase were the increasing of the dislocation motion and the dissolving of some precipitated phases.
分析了合金的强化机制,认为合金中高体积分数的弥散相和沉淀相对位错的钉扎作用,是合金强化的主要原因;挤压后细小弥散的初晶硅相同样起到了强化作用;高温条件下,位错的运动能力增强,部分沉淀相溶解是其强度降低、塑性增加的主要原因。
