本文测定了氮含量为0.08，0.14和0.22wt%的316不锈钢在298，653和823 K时的J-R曲线。由J-R曲线确定了对应于0.2mm裂纹扩展的弹塑性断裂韧性（J0.2）。在所有试验温度下，含氮量为0.14wt%的钢的J0.2值最高。
In the present investigationJ-R curves have been determined for SS 316 LN with nitrogen contents of 0.08, 0.14 and 0.22 wt% at 298, 653 and 823 K. Elastic-plastic fracture toughness (J0.2) corresponding to 0.2 mm crack extension, was determined from theJ-R curves. For all test temperatures,J0.2values were the highest for the steel with 0.14 wt% nitrogen.
