Design and development of a new high entropy alloy by powder metallurgy
Paper i proceeding, 2016

In this work a new high entropy alloy composition has been designed with the aim of tailoring the microstructure to achieve the required properties in cutting tools. For this purpose, it has been taken into account the characteristics of each of the elements involved, combined with the calculation of its phase diagram by thermodynamics simulations. The new composition has been developed by casting, and also by powder metallurgy. In most of the works found in the literature the powders are obtained by mechanical alloying, however in this work the powders are also obtained by atomization in order to reduce the contamination and to obtain powder particles with a more homogeneous composition. Finally the samples consolidation has been performed by spark plasma sintering.
