摘要
为综合评定金属材料的尺寸稳定性特性,提出了“圆环开口法”.实验证明,与以往棒状试样的一维长度测试方法相比,这种方法具有精度高、测试周期短、形位变化敏感等优点,是试验研究的有效方法.
Open Ring Method' has been proposed to evaluate the dimensional stability of metal materials comprehensively. The tests showed that, compared with the original technique by measuring the length of bar specimen, this method has chacteristics of high precision, short period of measurement and high sensitivity to the change of dimension.
