日本京都大学工程系新宫秀夫教授等利用固相制造合金粉的机械合金化,成功地制出镍钛非晶合金粉。这种方法是在半球形的凹形加工器具中加入材料粉,再用凸形球形加工器具压缩,由于能简单高效制造合金,放作为新的机械合金化法而引入注目。机械合金化是将作为原料的二种以上金属粉压粉、反复折叠而混合并合金化。其优点在于并不使金属熔融,故对熔点和沸点有 Kyoto University, Department of Engineering, Professor Shinomiya Shinkoi and other solid-phase alloy powder manufacturing machinery alloying, successfully produced Ni-Ti amorphous alloy powder. This method involves adding powder material to a hemispherical concave tool and then compressing it with a convex spherical tool to bring attention as a new mechanical alloying method due to the simple and efficient manufacturing of the alloy. In mechanical alloying, two or more metal powder compacts as raw materials are repeatedly folded, mixed and alloyed. The advantage is that does not make the metal melt, so the melting point and boiling point
