摘要
通过力学试验研究分析管线钢X70、X65中重要组分MA岛对力学性能的影响,得出MA岛的尺寸、分布、形态、数量对管线钢的屈强比、屈服强度、落锤影响的规律。
Size, distributing, morphology and number of the MA island influencing yield ratio, yield strength and DWTr of the pipeline steel are introduced in the paper by analyzing influence of the MA island on mechanical properties in X70 and X65 pipeline steel.
