Abstract
U shape bolts using for automobile fractured during transport process. The fracture position was located at the forged and bended part. The fractured bolt was researched by macroscopic and microcopic analysis. The results show that over burning happened because of the too high inductive heating temperature and hot crack formed by stresed. Finally after cooling the crack extended under low stress and led to the fracture.
