设计了一种微型拉伸试样，用结构均匀的材料X60钢测试了微型拉伸试样的拉伸强度的可靠性,发现试样尺寸对拉伸强度的影响很小，微型试样测量值与标准试样的差别不大，可以用微型试样测量Gleeble样品的强度，在高性能管线钢的研究中发现，微型拉伸试样的强度值和显微硬度值缺少一一对应关系，有必要做微型试样的拉伸试验，提供更为可靠的数据 A kind of micro-tensile specimen was designed. The reliability of the tensile strength of the micro-tensile specimen was tested by X60 steel with uniform structure. It was found that the sample size had little effect on the tensile strength. The micro-specimen measurement value And the standard sample is not very different, you can use the micro-sample to measure the strength of Gleeble samples in the study of high-performance pipeline steel found that the tensile strength of micro-tensile specimens and micro-hardness value of the lack of one to one correspondence, there It is necessary to do the tensile test of the micro sample to provide more reliable data
