Abstract

Platinum containing around 11.1 at.% chromium or vanadium undergoes an ordering transformation upon heat treatment, resulting in the formation of ordered domains with the Pt₈Ti superlattice structure. The formation of these ordered domains, which are dispersed in a disordered matrix, results in an increase in hardness. Hardness is observed to be sensitive to domain size, with a maximum hardness at around 5 nm, if the ordered volume fraction is high.
