摘要
对GH132高温合金的低温力学性能进行了试验研究。给出了其在4．2，13，20，30，40，77K下的拉伸曲线和试验结果，并且对其低温下的冲击韧性、泊松比、线膨胀系数等进行了较为全面的试验研究。结果表明GH132高温合金的低温性能也较为理想。
Give a detail research on the cryogenic mechanical properties of high Tc132 alloy. The tensile curves and experimental data have been got separatly in 4.2K, 13K, 20K, 30K,40K and 77K. At the same time we got its impact ductility, Poisson's ratio and thermal expansion by experiments. According to the experimental results, we find that the cryogenic mechanical properties of high Tc132 alloy are desirable.
