用配以适当熔剂的碳酸稀土直接对ZLl02合金进行变质处理,不仅大幅度提高了合金的力学性能,而且变质具有长效性;通过比较变质前后的合金组织以及微区成分分析,探讨了稀土在结晶过程中的行为.
The modification of ZL102 alloy directly with rare earth carbonate with appropriate flux not only greatly improves the mechanical properties of the alloy, but also has the long-lasting effect of metamorphism. By comparing the microstructure and the microstructure of the alloy before and after metamorphism, Behavior during crystallization.
