Influence of thermo-mechanical history on the ordering kinetics in 18 carat Au alloys

Nadine Baluc, Steven Van Petegem, Helena Van Swygenhoven, Marina Garcia Gonzalez

Precious alloys are subjected to a series of mechanical and thermal operations during manufacturing. For 18 carat gold alloys the processing operations can induce L1(0) ordered nanodomains, known to lead to the buildup of residual stresses, which are the p ...

Enhanced precipitate growth at reduced temperatures during chemical ordering in deformed red gold alloys

Nadine Baluc, Steven Van Petegem, Helena Van Swygenhoven, Samy Hocine, Marina Garcia Gonzalez

Manufacturing of red gold components relies widely on controlling the formation of ordered precipitates during thermo-mechanical processing. The ordered phase hardens the material, makes it less workable and introduces residual stresses. We show that an in ...
