In this work a new high entropy alloy (HEA) has been designed with the aim of tailoring the microstructure to achieve the required properties for a cutting tool. For this purpose, it has been taken into account the atomic size and mixing enthalpy of involved elements together with the calculation of its phase diagram by thermodynamic simulations.
The new composition has been developed by casting and by PM to process these alloys. In the first step of the PM processing the powder is obtained by two ways: mechanical alloying and atomization. In most of the works found in the literature the powders are obtained by MA, 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 powder consolidation has been performed by spark plasma sintering.
