Abstract:Drawing fracture samples of 82B wire rods were analyzed by the optical microscope(OM),scanning electron microscope(SEM)and micro-sclerometer(MS). The results showed that deformation martensite was the reason for 82B wire rods fracture during drawing process.The cause of occurrence of deformation martensite in 82B wire rods was discussed,and the measures of avoiding the occurrence of deformation martensite were put forward.
