Microstructure of an equiatomic CuPd alloy after severe plastic deformation and subsequent ordering

Abstract

The microstructure of an equiatomic CuPd alloy after severe plastic deformation (SPD) and prolonged heat treatment in the ordering temperature range has been studied. A highly fragmented nonuniform microstructure with high defect density is shown to be observed after SPD. After prolonged heat treatment, the bulk of the material is recrystallized and B2-type ordered (average grain size is 0.3 to 0.35 μm). Alloys and Compounds, 2013, vol. 581, pp. 625-631.
