【Abstract】 The present work was concerned with the fracture behavior of mild steel with residual stress. The results showed that at the characteristic transition temperature of low-temperature brittleness T_c the material has the crack arrest property. This finding is very important for the critical temperature T_c being used to evaluate the brittleness of welded structures.更多还原
