The Microalloying Effects in Cu-based Bulk Metallic Glasses YUE Li Jie1, a, HAN Jin Sheng2, b, XIE Kun1, c 1School of Material Science and Engineering, Shandong University of Science and Technology, Qingdao 266510, China 2School of Civil Engineering and Architecture, Shandong University of Science and Technology, Qingdao 266510, China ayuelijie26@126.com, bhjsheng2008@163.com, cxie.kun@126.com Keywords: Cu-based bulk metallic glasses; glass forming ability; thermal stability; corrosion resistance; polarization curve.
Since the successive development of Cu-based bulk metallic glasses by Inoue [1], Johnson and others in the late 90s, much effort [2~4] has been devoted to study the alloy systems, properties and engineering applications of Cu-based bulk metallic glasses.
The ultimate aim of amorphous alloys research is to develop the bulk metallic glasses with high glass forming ability and useful engineering properties.
