研究了净化Ni_(75)B_(17)Si_(8)合金液的方法以及净化对非晶形成能力的影响,通过净化工艺消除合金液内的异质质点可提高合金液的非晶形成能力;釆用净化和急冷相结合的工艺制备出了20×10×0.5(mm~3)的Ni-(75)B_(17)Si_(8)非晶合金试样。
The method of purifying Ni_ (75) B_ (17) Si_ (8) alloy liquid and the effect of purification on the amorphous formation ability were studied. The elimination of heterogeneous particles in the alloy liquid by the purification process can improve the amorphous formation ability of the alloy liquid. Preclude the preparation of a 20 × 10 × 0.5 (mm ~ 3) Ni- (75) B 17 Si 8 amorphous alloy sample by the combination of purification and quenching.
