摘要
检验发现ＰＣ钢丝的拉伸试验断口有５ 种形态。研究钢丝力学性能与这５ 种断口的对应关系，分析产生不正常断口的原因。
Five kinds of tensile fractures of PC steel wire are discovered in test The relations between mechanical properties of PC steel wire and the five kinds of fractures are studied,and the reasons causing unusual fractures are analyzed It is considered that the mechanical properties of PC steel wire can′t get up to standard is due to the defects in wire rod
