Experiments on powder metals

This thesis describes an experimental program aimed at the development of elastic-plastic constitutive relations for cold compaction of ANCOR MH-100 iron powder. A systematic experimental program consisting of triaxial compression, torsion ring shear, uniaxial strain compression, and simple compression test systems has been conducted to investigate the room temperature deformation response of powders ranging from a relative density of n = 0.4 - 0.9. A torsion ring shear apparatus has been designed and fabricated to investigate the frictional behavior of iron powder. The torsion ring shear apparatus is also used to examine the important interface frictional behavior between the powder compact and confinement dies.
