; 文献标识码:A Two problems overlooked in binary phase diagrams TANG Ren-zheng, TIAN Rong-zhang (School of Materials Science and Engineering, Central South University, Changsha 410083, China) Abstract: Two usually over looked problems are in the binary phase diagrams. First, the crystal style of many interphases would transit in the binary systems, the crystal style transition......
