摘要

采用自制试验装置研究了在静态条件下镁合金与N2之间的相互作用

特别研究了在N2气氛下Mg及镁合金的燃点情况。结果表明

添加Y、Ce、Nd和Ca都能提高Mg在N2气氛下的燃点

其中添加Ca的试验效果最好

Ca的质量分数为5.0%时燃点超过了1030℃。Ce的添加使Mg-3Y合金的燃点先降后升、Mg-3Ca合金的燃点先升后降、Mg-1Nd合金的燃点显著提高

Ca的质量分数为4.5%时Mg-1Nd合金的燃点达到1022℃。镁合金在N2气氛中的燃点明显高于大气中的燃点。

Abstract

We have developed an experimental device to examine the reaction of magnesium alloy with N2 under static condition

especially ignition point of Mg and Mg alloy.It is found that ignition point of Mg alloy under nitrogen atmosphere can be increased with additions of Y

Nd and Ca

especially Ca addition.Ignition point of Mg-3Y and Mg-3Ca can be decreased with Ce addition

while ignition of Mg-1Nd alloy can be greatly increased with Ca addition.Ignition point of Mg alloy under nitrogen atmosphere is obviously higher than that of ones in air.
