| 摘 要： | 本文应用扫描电镜、能谱分析、电子显微镜等多种分析方法,对201及200Cu两种不锈钢钢丝的断裂原因进行了研究分析。结果表明,由于200系不锈钢的奥氏体稳定性较差,较易发生晶界腐蚀,在拉制过程中因所受应力不均匀,导致微裂纹产生,在随后的多次拉拔工艺中发生扩展开裂。

| Abstract: | By means of SEM,EDS and metallography microscope,the fracture reasons of stainless steel wire of 201 and 200Cu were analyzed. The results show that un-stability of austenitic phase brought about corrosion between grain boundary easily,and the un-equality stress during drawing brought about small cracks and then expand at the following drawing process which resulted in the failure. |
