Texture evolution in platinum: the role of non-octahedral slip

An anomalous deformation texture evolution has been observed in high-stacking-fault-energy pure platinum during cold rolling. A maximum of 98% thickness reduction, equivalent to a true strain of 3.9, was imposed. The evolution of texture observed during rolling is characterised as sluggish and the starting texture was retained up to very large rolling strains. The evolution of a characteristic rolling texture and its strengthening was dramatic...
