摘要
Abstract
The yield strength of 304,316L,and 32001 stainless steel bolts was measured using the physical stretching method and the extensometer stretching method,and the reasons for the deviation between the two measurement methods were studied.The results show that the deviation rate between the measured values of the physical stretching method and the extensometer stretching method was 0.9%to 6.6%,with the extensometer method measuring lower values.The heat treatment state had the most significant impact on the deviation rate,and the overall deviation rate of 316L steel was higher.The reason for the deviation was the limitation of macroscopic displacement measurement by physical stretching method and the concentration of thread stress.关键词
