ti含量对nial--cr(mo)共晶合金凝固组织的影响
Keywords: 金属材料,金属间化合物
Abstract:
？添加ti降低了nial--cr(mo)共晶合金凝固过程中nial/cr(mo)共晶生长速度,导致nial/cr(mo)胞状共晶组织的粗化,并因合金偏离共晶成分而促进先共晶nial相的形成.在添加ti的nial--cr(mo)共晶合金中,ti主要分布在基体nial相中.随着ti含量的提高,过饱和的nial(ti)基体发生分解,促进了ni$_{2}$alti相的形成,并且nial/cr(mo)胞状共晶组织发生退化.ni--33al--28cr--3mo--5ti共晶合金的nial基体中析出细小的cr(mo)相,cr(mo)共晶相中析出细小的nial相.
