Hello, My material science teacher posed an interesting question today. During the making of an alloy, would it be better to quench it or let it cool slowly? At first I thought the answer was obvious: quench it quickly so in the case the two elements have different melting temperatures they don't separate. But then someone brought up the thought of diffusion... if it is cooled slowly then it will have a chance to diffuse, therefore making it more uniform. Was my intuition correct or is there more behind this? Thanks.
