前言金属蠕变试验的第二阶段特点是蠕变速度基本上不变。将试验测得的变形量1与时间τ数据描于坐标纸上所得的蠕变曲线(变形——时间曲线)的第二阶段近似于直线。同一材料随应力及温度的改变、各阶段持续时间不同,甚至相差很大,因此测量的时间间隔也应不同.本文试图对试验结果进行统 Preface The second phase of the metal creep test is characterized by a substantially constant creep rate. The second phase of the creep curve (deformation vs. time curve) obtained by plotting the experimentally measured deformation 1 and time τ data on a coordinate paper approximates a straight line. The same material with the stress and temperature changes, the duration of each stage is different, or even a big difference, so the measurement interval should also be different.This paper attempts to test results
