It is showed that a small quantity of strontium can increase the formation temperature of primary phase α-Mg and decrease the recalescence temperature difference;strontium enriches in front of the grain growth interface during solidification,which restrains the growth of the grains;the grain size has decreased dramatically from 425μm to 147μm under this experiment conditions.

结果表明,微量Sr能提高AM60B合金的初生相析出温度,降低再辉温差;凝固过程中Sr位于晶粒生长前沿,抑制了晶粒的长大,从而有效地细化了晶粒,在本试验条件下,从约425μm降至约147μm。

The simulated results show that using the method can not only reveal dendrite morphology and micro-segregation but also represent the recalescence phenomenon.
模拟结果显示这种方法可以显示出枝晶形貌和显微偏析,同时可以再现凝固过程中的再辉现象。
These principles in elude heat transfer and recalescence, thermodynamics of metastable and non-equilibrium solidification, growth kinetics and solute redistribution.
这些原则包括:传热及温度回升,亚稳及非平衡凝固热力学,生长动力学及溶质分布。
