【 摘 要 】

Colour and hardness were measured on a series of alloys along the 76 wt.% Au line of the Au-Cu-Al system. Complex, non-monotonic behaviour was observed, which is shown to be correlated with microstructural changes. The available colours include reddish, yellow, 'apricot', white and purple. The hardness of as-cast material varies from 150 to 500 Vickers. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
