Editorial on Oxidation of Novel Metallic Materials (Intermetallics, MMCs, HEAs…)
Résumé
Over the past ten years, new methodologies have emerged that have markedly accelerated the development of new alloys. In particular, the utilisation of rapid high-throughput techniques and novel numerical alloy design approaches now enables the development of alloys with multiple optimised characteristics for a specific application. These characteristics may concern thermomechanical properties (such as strength and creep resistance), or other properties (such as density or cost), and may also relate to the ability of the alloy to achieve good behaviour in a corrosive environment at high temperature. In this context, the emergence of high-entropy alloys (HEAs) and concentrated complex alloys (CCAs), comprising four to six concentrated elements, has led to the emergence of new fields of research. However, in this new paradigm of ‘combinatorial metallurgy’, there is also an increased scope for innovation in the case of ‘conventional’ steels or nickel-based alloys or light alloys, since they may contain an even greater number of alloying elements.[...]
