Abstract
Evidence that ductile fracture requires a compressive stress on the dislocation arrays close in value to that required for cleavage is presented. It is shown that the ductile fracture stress [sgrave]f is related to the grain diameter l by the equation [sgrave]f=[sgrave]0+kl −1/2, where [sgrave]0 and k are constants. This is the same form of relationship as already found for cleavage and the slope k is practically the same for both types of fracture.Keywords
