Since its discovery, aluminium alloys have played a significant role in several sectors of industrial developments. The combination of high strength and low density has made these alloys attractive and played a crucial role in the automotive and aerospace industry. However, newer developments have brought exciting possibilities in high temperature and high-temperature alloy developments in the last few years. One of them is the addition of coherent, ordered precipitates of nanometric sizes. These precipitates also promote hierarchical structures and resistance to microstructure coarsening. It is also increasingly realised that controlled segregation at the precipitate/matrix interface can control and improve room and high-temperature properties. This article focuses on these developments that are expected to open up new possibilities and applications in the automotive and energy sectors.
