摘要
拉伸试验是金属材料力学性能试验中最常见的试验方法。不同国家的拉伸试验标准对拉伸试验设备、试样尺寸、温度范围、试验速度、试验结果处理与修约的规定不尽相同,我们主要对RCCM、ASTM、ISO与GB相比较,列举了它们之间的差异。
Tension test is the most commonest test method of Metallic materials mechanical properties test.Requirements of testing apparatus,specimen dimension,temperature range,test results determining and data rounding in different standards are not completely same,and several differences were listed by main comparison of RCCM,ASTM,ISO and GB by us.
