摘要
以TC4钛合金大型模锻件二梁热锻过程中晶粒分布和相分布为研究对象,运用有限元分析软件对其热加工过程进行数值分析,分析了坯料初始加热温度和压力机速度对锻件晶粒分布及相分布的影响规律。研究表明,坯料初始加热温度为980℃,同时采用二级直线阶梯式变速加载的压力机速度方案有利于得到细小均匀的微观组织。
In order to study the grain distribution and phase distribution of the large forging of TC4 Ti-alloy second-beam, the finite element analysis software was used to numerical analyzed the thermal process of TC4 Ti-alloy. The influence law of blank initial heating temperature and press speed on the distribution of grain and phase was revealed. The research showed that fine and uniform microstructure will be obtained when the blank initial heating temperature was 980 ℃ and at the same time adopted the press speed scheme of second straight ladder variable loading.
