表面机械研磨处理对316L不锈钢组织和性能的影响 刘刚1,兑卫真2,杨晓华2 (1.中国科学院金属研究所沈阳材料科学国家(联合;2.福州大学测试中心,福建,福州,350002) 摘要:对2.8mm厚的316L不锈钢板的上下表层进行机械研磨处理(SMAT),对经过不同时间的SMAT后的样品的表层组织进行金相观察,并测量SMAT不同时间的样品的硬度,抗拉强度.结果表明,经过表面机械研磨处理不同时间后,在316L不锈钢板表层获得了不同厚度的表面强化层,强化层组织为沿厚度方向由纳米晶层向微米晶层过渡的梯度组织;随着SMAT时间的增加,总的强化层厚度增加;表面组织的变化导致了表面硬度明显增加,整体材料的屈服强度增加;表面机械研磨处理时间对性能的影响并非线性增加,表面硬度和整体材料的屈服强度在处理5min时增加显著,处理时间继续增加到15,30和60min,它们的增加速度很小.拉伸断口表面形貌......
