摘要

本文介绍了金属材料蠕变特性及相关过程的实验研究成果。考虑了单轴拉伸、时效和温度对焊接接头强度的影响、复合应力以及环境化学相互作用因素对蠕变和蠕变断裂强度的影响。给出了一个等效应力，允许描述在相同主应力值的单轴拉伸和相等的多轴拉伸下蠕变寿命的差异。

Results of Experimental Studies of Creep and Long-Term Strength

The paper presents the current results of experimental studies of the creep properties of metallic materials and related processes. Uniaxial tension, the effect of aging and temperature on the strength of a welded joint, complex stress, and the effect of factors of chemical interaction of the environment on creep and creep rupture strength are considered. An equivalent stress is given that allows describing the difference in creep lifetimes under uniaxial tension and under equal multiaxial tension for the same value of the principal stress.
