本文测试了Zr-4合金棒真应力-真应变曲线,并且进行了由於缩颈造成的三轴应力效应的修正。对真应力-真应变曲线进行了数学处理,给出了Zr-4合金的全面拉伸性能。
In this paper, the true stress-strain curves of Zr-4 alloy rods were tested and the triaxial stress effects due to necking were corrected. The true stress-true strain curve is mathematically treated, and the overall tensile properties of Zr-4 alloy are given.
