✦ Synopsis

The fracture behavior of mild steel with residual stress is studied. Results show that at the characteristic transition temperature of low-temperature brittleness T:, which has been recommended as the critical temperature to evaluate the brittleness of mild steel, the material possesses the crack arrest property. A steep transition of the fracture load of the material with residual stress occurs at the temperature T$. This finding is very important, allowing the critical temperature Tr to be used to evaluate the brittleness of welded structures.

From measurements of Luder's band-front velocities it is concluded that hydrogen does not affect the activation energy for separating a dislocation and its atmosphere and thereby the delay-time for yielding. Suppression of the upper yield point by hydrogen seems rather to be caused by local stresses
