Thermodynamics Analysis of Melting Loss of Ca,Sr in AZ91D Magnesium Alloy Melt
摘要
分别研究了在熔剂保护下和在气体保护条件下
钙、锶元素在AZ91D镁合金熔体中的烧损情况
并从热力学角度分析钙、锶元素在熔剂保护下的烧损原因。研究结果表明
钙、锶在熔剂中均与氯盐发生反应
使得钙、锶烧损程度较大;锶与氯盐反应的热力学倾向更大
其烧损更快。
Abstract
The paper has studied the melting loss of Ca
Sr element in AZ91D magnesium alloy melt
under flux protection and protective atmosphere condition
respectively.The reasons for melting loss of Ca
Sr under flux protection are analyzed through thermodynamics aspect.The results show it is larger for the extent of melting loss of Ca
Sr under flux protection
even sharper for Sr.The main reasons are that Ca
Sr can react with chloride in flux.The tendency of thermodynamics is larger for the reaction between Sr and chloride.
