- 摘要:
- Sn-10%Sb合金在856~960℃可以发生温度诱导的液-液结构转变。研究了温度诱导液-液结构转变对Sn-10%Sb合金凝固行为及组织的影响。结果表明,合金熔体经历结构转变后,凝固时所需过冷度增大,并且凝固组织显著细化。The Sn-10%Sb alloy can happen from 856 ℃ to 960 ℃ temperature-induced liquid-liquid structure transition.The effect of temperature-induced liquid-liquid structure transition on the solidification behavior and microstructure of Sn-10% Sb alloy was studied. The results show that the required supercooling degree increases and the solidification microstructure is refined obviously after the structural transformation of the alloy melting.
