Preparation and Mechanical Properties of Misch Metal Based Bulk Metallic Glasses Suo Zhongyuan1,Meng Likai1,Qiu Keqiang1,Wu Xiaofeng1,Zhao Wei1 (1.Faculty of Materials and Chemical Engineering, Liaoning Institute of Technology, Jinzhou 121001, China) Abstract:The formation, thermal stability and mechanical properties of Misch metal (Mm)-based alloy bulk metallic glasses (BMGs) with composition......
] reported that amorphous alloy with the composition of Mg65Cu25Y10 could be produced with thickness up to 4 mm by conventional mold casting technique, Mg-based bulk metallic glasses (BMGs) have been proposed as a new kind of bulk metallic glasses due to their relatively low density[1-13]. It is known that an amorphous phase can serve as a precursor to prepare an expected structure, e.g.......
