Abstract
Tensile, microhardness and fatigue tests were carried out on palladium -manganese alloys with manganese contents in the range 10-25 at.%. Eac h alloy was examined in three structural forms: a disordered form, an Al3Zr-ordered form and a hydrogen-induced Ll(2)-ordered form. While th e disordered and Al3Zr-ordered forms of a particular alloy have quite similar mechanical properties, the Ll(2)-ordered form of the alloy dif fers markedly from the others. It has been found that the Ll(2)-ordere d form of an alloy has enhanced strength and hardness, together with r educed ductility and fatigue life, compared with either the disordered or Al3Zr-ordered forms. These differences are attributed to the forma tion of a hydride phase in each alloy during the preparation of the Ll (2)-ordered structure.
