2-High Entropy Alloys

Conventionally, simple solid solution structures, such as CFC or BCC are formed in high entropy alloys instead of ordered crystalline compounds due to the high entropy effect, starting from liquid synthesis methods as arc melting or induction melting process. The ingots were then remelted at least three or four times to improve the homogeneity under high vacuum.

Now, many studies are also focused on solid state technologies to produce HEA alloys and, between these, in our case, sps (spark plasma sintering) and WDE (microonde ) are selected to evaluate possible, simple and alternate technology processes. Starting from the PM (powder metallurgy) , the equiatomic Fe, Al, Ni, Co and Cr metallic powder mixtures were prepared
