Alloy variants emphasized systems with/without pre-alloyed manganese and admixed elemental tin powder. Systems with pre-alloyed manganese demonstrated an inferior response to die compaction and only achieved a density of 91% of theoretical after sintering. Conversely, the mixture that contained a trace addition of tin and was devoid of manganese densified to >98%. In the T6 state, this particular PM variant exhibited stiffness and yield strength that were comparable to wrought 6013-T6 but maintained a limited tensile ductility. The latter trait, as well as UTS and fatigue performance, were all improved significantly with the inclusion of a hot swaging step after sintering. As hot swaging eliminated the bulk of residual porosity in the sintered preform, this was believed to have underpinned much of the gains realized.enAluminumPowder MetallurgySinteringHot SwagingTensileFatigue
