摘要/Abstract

摘要： 采用高温拉伸试验方法，模拟研究了Monel400合金焊接接头HAZ的“热脆”行为。重点探讨了不同线能量及Mg含量的影响。研究结果表明：Monel400接头HAZ在500～850℃之间存在低塑性的热脆区。减少线能量，适当提高合金的Mg含量，有助于降低合金的热脆性，因而提高抗裂性能。

Abstract: The HAZ "hot short” behaviour of Monel 400 alloy joint is simulated and investigated. The effect of various heat input and Mg content is inquired. The result shows that there exists a lowplasicity "hot shorts" zone at temperature range 550～850℃ in the HAZ of Monel 400 alloy joint. Lower heat input and appropriate higher Mg content are advantageous to decrease the "hot short" susceptibility and thereby improve the resistance to cracking.
