摘　　要：通过DSC热分析技术研究了成分和升降温速率对GaInSn三元合金和GaIn二元合金的固-液相变行为的影响。结果表明,GaInSn三元合金和GaIn二元合金升温过程中的固-液转变(熔化)温度十分稳定,对成分波动不敏感;而降温过程中的液-固转变(凝固)温度则随成分的波动而显著变化。此外,讨论了Ga基合金过冷度与Ga含量和冷却速率之间的关系。The influence of composition and heating/cooling rate on phase transformation behavior of GaInSn ternary alloy and GaIn binary alloy is researched by DSC technology.Results show that the melting point GaInSn ternary alloy and GaIn binary alloy is very stable and not sensitive to composition;the solidification point is sensitive to the composition.Besides that,the relationship between the undercooling of Gallium-based alloy and the content of Gallium/cooling rate is also discussed.
