用质量分数3.5%的NaCl溶液作为腐蚀液,滴于低碳铁素体钢、09CuPCrNi钢和低碳贝氏体钢的表面并形成薄液膜,用金相显微镜观测薄液膜下三种钢的初期腐蚀.低碳铁素体钢和09CuPCrNi钢均出现了明显的晶界择优腐蚀,而低碳贝氏体钢没有出现明显的晶界择优腐蚀.钢基体的电化学阻抗谱和极化曲线测量结果显示低碳贝氏体钢具有最高极化电阻和最小腐蚀电流,表明细晶组织的低碳贝氏体钢的初期腐蚀速率低于其他两种钢

采用ZL-2超强脉冲放电装置实现了7A04超硬铝合金试件中斜裂纹的止裂实验.在瞬间超强脉冲电流作用下,裂尖前缘发生了强烈的绕流热集中现象,斜裂纹裂尖附近金属熔化,钝化了裂尖,阻止了干线裂纹源的开裂趋势.对止裂前后裂尖附近金属组织进行了显微观察,并对止裂前后裂纹附近的断口进行了对比分析;在万能材料试验机上对试件进行了拉伸力学性能对比测试.研究表明:在斜裂纹止裂瞬间,裂尖熔化,同时实现了组织超细化,提高了裂纹的扩展功,改善了试件的抗拉力学性能
