ZL101钠盐变质处理过冷度、变质时间和加入量的关系研究
|
摘要
研究了钠盐三元变质剂的加入量对ZL101合金变质过冷度和变质时间的影响。试验结果表明:在所建立的钠盐三元变质剂加入量、变质处理过冷度和变质时间三者的准三维图上,可以直接获得合金在最佳变质效果时(变质处理凝固时过冷度最大),钠盐加入量与变质时间的对应关系;也可以获得合金在具有变质效果时(变质处理凝固时过冷度大于4℃),钠盐加入量与变质时间的对应关系。
This research focused primarily on studying the effect of different amounts of ternary sodium salt modifier on the super-cooling and modification time during metamorphic treatment of ZL101 alloy. A quasi-threedimensional curved surface diagram was established based on the addition amount of sodium salt modifier,metamorphic treatment super-cooling degree and modification time, in which the relationship between the addition amount of sodium salt and the modification time upon appearing the optimal metamorphic effect(the maximum super-cooling degree during the modification of solidification treatment), and upon appearing the metamorphic effect(when super-cooling degree is more than 4℃ during the setting treatment), could be directly obtained.
