Abstract

Heat treatment of platinum-5 wt.% copper (Pt-5% Cu) below 500°C is known to result in an ordering transformation which can significantly increase the hardness of the alloy. Microsample tensile testing of Pt-5% Cu shows that low-temperature heat treatment of previously cold-worked specimens results in an increase in yield strength and tensile strength, with a maximum in strength occurring after heat treatment at 300°C; but ductility is unchanged.
