摘要 在高真空下,研究了50 % (79 % Si O2 + 12 .5 % B2 O3 + 2 .2 % Al2 O3 + 0 .6 % Ca O + 5 .7 % Na2 O) ( 简写为 Na Ca Al B Si) + 50 % ( Na2 B7 O4) 对 Cu50 Ni50 和 Cu70 Ni30 合金熔体循环过热过程中过冷度稳定性的影响。结果表明,50 %( Na Ca Al B Si) + 50 % ( Na2 B7 O4) 玻璃对合金熔体的净化过程为物理—化学复合净化, 且在( Na Ca Al B Si) 净化剂中加入( Na2 B7 O4) 玻璃形成的净化剂粘度适中,因此合金熔体在2 ~5 次循环过热过程中可以获得稳定深过冷。 The undercooling and its stability of Cu50Ni5050 and Cu70Ni30 alloy melts were investigated using 50%(79%SiO 2+12.5%B 2O 3 +2.2%Al 2O 3+0.6%CaO+5.7%Na 2O)+50%(Na 2B 7O 4)glass slag techinque in vacuo.The results show that stable undercooling can be achieved by physicochemical denucleating processes of 50%(79%SiO 2+12.5%B 2O 3 +2.2%Al 2O 3+0.6%CaO+5.7%Na 2O)+50%(Na 2B 7O 4)molten glass because of its appropriate structure and viscosity.
