Abstract Scope |
This talk will review research on nanostructured multi-principal element alloys (NM-PEAs). This topic combines two popular research areas in materials science - 1. nanostructured materials, and 2. multi-principal element alloys. This topic has been reviewed in the literature by several authors including the speaker(Koch, 2017) and Hache’ et al. (2020). Most processing methods for NM-PEAs have involved severe plastic deformation ( especially mechanical alloying of powders, or to a lesser extent, high pressure torsion). Limited studies of NM-PEAs made by magnetron sputtering, and most recently, electrodeposition, will be described. This talk will emphasize enhanced properties that NM-PEAs may provide. These include mechanical properties (hardness and strength), wear resistance, thermal and phase stability, corrosion resistance, and selected functional properties. The alloys to be discussed include the most studied 3d element alloys, refractory metal alloys, and a low density alloy. |
