    BASIC KNOWLEDGE OF RESIDUAL STRESS DETERMINATION——LECTURE No.5 REVIEW ON THE RELATIONSHIP BETWEEN SURFACE INTEGRITY AND FATIGUE FRACTURE RESISTANCE OF METALLIC MATERIALS AND COMPONENTS

      摘要
    • 摘要: 论述了金属材料/零件的表面完整性与其疲劳断裂抗力之间的关系。试验结果表明,表面完整性中的残余应力、组织结构与表面粗糙度这三个因素对疲劳断裂抗力是最有影响力的三个因素。

       

      Abstract: The relationship between surface integrity (SI) of metal materials and fatigue fracture resistance (FFR) are discussed. The experiments have been shown that the three factors of residual stress microstructure as well as surface roughness including in the all factors of SI have most influence on the FFR.
