Abstract:In order to provide reference for heat treatment of alloy seamless tubes,the effects of heat treatment process on the micostructure and tensile strength of cold-rolled N06230 alloy seamless tubes was studied by means of optical microscopy (OM),scanning electron microscopy (SEM) and tensile test at room temperature. By OM and SEM characterization,the area percentage of M6C carbides and grain size in the range of 1 200-1 300 ℃ and holding for 0.5-5.0 h were analyzed,and the kinetic model of grain size growth was established. The results show that there are a lot of W-rich M6C carbides in the alloy,which have the characteristics of granular and dispersive distribution in the transverse direction,distributed in the chain along the rolling direction. Some M6C carbides show elliptical characteristics,and the area percentage is about 1.97%. The tensile strength of seamless tube decreases with the increase of heat treatment temperature and the prolongation of holding time.
