Abstract
In this article, the changes of HAZ impact toughness in induction heating bend pipes with X70 and X80 grade were deeply discussed. Firstly through the production data statistics to conduct trend analysis;and then using thermal simulation method to carry out thermal simulation and mechanical properties test for each subdivided area, then to be verified with trend. Finally, the microstructure changes of the heat affected zone, from the original state to state quenching process were made a full analysis, explained the mechanism of performance changes from the perspective of organizational form. The experiments showed that the performance and the microstructure of the induction heating bend pipes HAZ, including its coarse grain area, fine grain area and overlapping areas, were undergone significant changes. For this phenomenon, some suggestions and opinions for the relevant standards of induction heating bend pipes were put forward.关键词
