摘要(Abstract)：

将固溶处理的TWIP(Twinning induced plasticity)钢膨胀管在室温下进行约14%的膨胀变形,对钢膨胀前后的微观组织进行观察,研究膨胀变形对TWIP钢的力学性能和电化学腐蚀行为的影响。结果表明:经固溶处理TWIP钢的组织为单相奥氏体并含有退火孪晶,经过膨胀变形后晶粒内出现机械孪晶,膨胀变形提高了钢的强度和硬度,降低钢的塑性和韧性。另外,膨胀变形导致TWIP钢的阴极极化曲线向左移动,自腐蚀电位向负方向移动,自腐蚀电流密度呈现不同程度的降低,膨胀后的极化电阻R_p均大于膨胀前,降低了钢的腐蚀速率,提高了TWIP钢的耐蚀性。

关键词(KeyWords)： TWIP钢;膨胀变形;耐蚀性;力学性能
