断面收缩率 - 434 we shall take the sample to test its physical properties ( mechanical properties , tensile strength , yield point , percentage elongation , reduction of area , impact value , brinell hardness )
我们将取样试验其物理性能（机械性能、抗张强度、屈服点、延伸率、断面收缩率、冲击值、布氏硬度） 。 - 434 we shall take the sample to test its physical properties ( mechanical properties , tensile strength , yield point , percentage elongation , reduction of area , impact value , brinell hardness )
我们将取样试验其物理性能（机械性能、抗张强度、屈服点、延伸率、断面收缩率、冲击值、布氏硬度） 。 - In the third ductility region , the reduction in area of the sn - undoped steel is larger than that of the sn - doped steel . this means that the hot ductility of the sn - undoped steel is better than that of the sn - doped steel
在第类脆性温度区内，不含sn钢的断面收缩率大于含sn钢的断面收缩率，即不含sn钢的热塑性要比含sn钢的热塑性好。 - Evaluation of uncertainty of measurement in testing for materials at ambient temperature has been discussed , including tensile strength ; lower yield strength ; proof strength , non - proportional extension ; percentage elongation after fracture and percentage reduction of area
摘要文章介绍了金属材料室温拉伸试验测量结果不确定度的方法，内容包括抗拉强度、下屈服强度、规定非比例延伸强度、断后伸长率和断面收缩率等性能指标。
