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
Results of dynamic and impact tests on mild steel are reviewed, and a criterion for dynamic yield is proposed, based on Cottrell and Bilby's theory of yielding. The criterion is applied to some of the published experimental data and a comparison is made with theory. The need for further experimental
A study has been made of the effect of dynamic strain-ageing on the initiation and propagation of ductile fracture in mild steel. Grain boundary carbide cracking has been found to contribute to void formation in the tempereture range 77ยฐK to 573ยฐK. Using scenning electron microscopy it hes been show
