Abstract : Fracture surfaces of 304 stainless steel were examined with a scanning electron microscope and inter void and inter particle spacings were measured. A significant relationship between inter void spacings and fracture stress was found. It was concluded that voids preceding ductile fracture could be initiated without the presence of secured phase particles in pure metals and 'clean' alloys. (Author)
