| Abstract: | Void generation has been compared for two heats of AF1410 steel in which the sulfur has been gettered either as particles of MnS or as CrS particles. Voids are nucleated at lower plastic strains when sulfur is gettered as CrS than when sulfur is gettered as MnS. Diffraction results indicate that the CrS has a monoclinic structure. |
