碳酸稀土对铝硅合金变质作用的研究
Study on Effects-modification of RE Carbonatefor Al-Si Alloy
【摘要】 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.
【Abstract】 ZL102 alloy was modified directly using RE2(CO3)3 mixed with fluxes, increasing significantly the mechanical properties of ZL102 alloy and prolonging the long-time effect of modification. The structure and micro-zoned composition analysis of ZL102 alloy before and after modification are compared to investigated the role of RE carbonate during crystallization.
