[Abstract]:The microstructure and mechanical properties of K465 alloy after heat treatment were studied. The results show that the 緯 'phase in the dendritic stem is cubic after heat treatment, and the volume fraction is 62. At the same time, the fine point carbide is precipitated, and the as-cast MC carbide is transformed into M6C. The results of high temperature aging heat treatment show that after 1 000 鈩，
