摘　　要：采用正交设计方法进行了材料的热处理及性能试验,并对该材料进行了弹性模量和线膨胀系数的试验测定,通过计算获得该材料在室温和高温时的弹性模量和线膨胀系数。对该材料性能的分析和评价表明:ZG1Cr10MoWVNbN耐热钢作为超超临界高温用耐热钢具有良好的常温力学性能;其弹性模量随温度的升高而下降;其线膨胀系数较小,并且随着温度的升高增幅也较小。The heat treatments of the steel are performed using orthogonal design method. Young＇s modulus and linear expansion factors are tested and measured. The Young＇s modulus and linear expansion factors at room temperature and high temperature are obtained by calculation. The analysis and evolution of the material show that ZG1Cr10MoWVNbN is a steel with high normal temperature mechanical properties. Its Young＇s modulus is declining with the temperature falling. Its linear expansion factors are smaller and its amplifying is smaller with the temperature going up.
