由Au-Al β′相组成的样品的轻度蚀刻表面表现出显著的闪烁外观和颜色变化。在这里描述和解释了对这种现象的调查。当样品在光线中倾斜时，单个颗粒产生的颜色变化是由于非常规则的薄片阵列的衍射。然而，始终如一地获得所需的微观结构需要了解这种合金系统的显着行为。还讨论了与该合金可能的商业应用有关的其它工艺性能。
Lightly etched surfaces of specimens comprised of the Au-Al β′-phase exhibit a remarkable sparkling appearance and play of colour. An investigation of this phenomenon is described and explained here. The play of colour produced from individual grains as the sample is tilted in light is due to diffraction from arrays of very regular lamellae. However, consistently obtaining the desired microstructure requires an understanding of this alloy system’s remarkable behaviour. Other technological properties which would be relevant to possible commercial application of this alloy are also discussed.
