Abstract

The effects of palladium doping on the structure of the antiphase boundary (APB) coupled dislocations and the APB energies in the deformed Ni₃Al alloy is reported. The chemical composition of the arc melted Ni_74.5Pd₂Al_23.5 alloy is closed to its nominal composition as revealed by an energy dispersive X-ray spectrometer in a scanning electron microscope. The dislocation structure of the alloy consists of undissociated dislocations induced by compressive deformation. Pd doping enhances the ductility of the alloy and the enhanced ductility is unlikely to result from the small decrease in APB energies.
