摘要
采用玻璃熔体净化法和电磁悬浮循环过热法消除Ni_(75),B_(17)Si_R合金液内的异质核心,研究了净化对该合金液非晶形成能力和所形成的非晶合金热稳定性的影响。采用净化和忽冷相结合的工艺制备出了20×10×0.5mm的Ni_(75)B_(17)Si_8非晶试样,试样的厚度较净化前提高了4倍。
The glass formability of Ni_(75)B_(17)Si_8 alloy melt and the thermostability
of this metallic glass formed from the melt can be enhanced by eliminating the
heterogeneous catalysts. The purification was done by cyclically superheating the
melt in special glasses and subsequently cyclically superheating it in electromagnetic
levitation apparatus. The purified Ni_(75)B_(17)Si_8 amorphous sample sized up to 20×10×
0.5 mm was prepared as four times the thickness of unpurified ones.
