In the present study, alloying of Ni with Cu was attempted using Ni and Cu elemental powders via high energy ball milling. The morphological and texture evolution during milling was studied. The {001} texture was observed in milled particles when they develop flaky morphology with large (L/D similar to 100) ratio and it changed to random texture when these flakes fragmented into tiny particles on further milling. These observations are rationalized by invoking the deformation mechanisms operating during milling. Extensive twinning was observed in the milled particles. The flaky nature of Ni is found to be stabilized with the addition of Cu with concomitant reduction in strain hardening compared to pure nickel. (C) 2016 Elsevier Inc. All rights reserved.
