Preparation and thermal stability of Pd40.5Ni40.5SixP19-x bulk metallic glassesYang Li,Yao-cen Wang,and Ke-fu Yao Department of Mechanical Engineering,Tsinghua University,Beijing 100084,China摘 要:<正>With the addition of Si to replace some P,Pd40.5Ni40.5SixP19-x(x=0,2.5,5,9.5,14,and 19 in atomic number fraction) bulk glassy samples with the diameter......
for simulating and predicting critical dimension dc of glass forming alloys. A group of Zr-Al-Ni-Cu and Cu-Zr-Ti-Ni bulk metallic glasses were designed based on the dc and their dc values were predicted by the ANN model. Zr-Al-Ni-Cu and Cu-Zr-Ti-Ni bulk metallic glasses were prepared by injecting into copper mold. The amorphous structures and the determination of the dc of as-cast alloys were......
