中厚板试样形状对拉伸性能的影响

摘要

通过对比试验分析了中厚板试样形状对拉伸性能的影响.从试验结果可知,中厚钢板的板厚1/4处组织性能优于板厚1/2处,拉伸试样的截面形状会对性能结果产生影响,圆形截面试样的性能明显优于矩形截面试样,且试样的形状、部位对伸长率的影响较大.%By contrast experiment,the effect of specimen shape on tensile property of heavy and medium plate was analyzed.The result indicates that the structure and property of 1/4 thickness were better than that 1/2 thickness.And the influence of tensile specimen section was emerged on tensile property,the property of circular section specimen was obviously better than that of rectangle and the influence of shape and position of specimen on elongation rate was rather strive.
