Abstract Scope |
The exceptionality of HEA lies in the formation of a single random solid solution which will determines their properties. The formation of this phase takes place thanks to a high configurational entropy derived from the high number of elements in its formulation. A study of the properties of the involved elements can predict the phase formation and, in fact, there are numerous works that propose the empirical rules to predict their behaviour. However, the kinetics of phase formation also play an important role in the formation of the final microstructure and must be studied for each HEA composition. In the present work, a new HEA composition has been designed and consolidated by two Powdermetallurgy techniques: conventional Pressing and Sintering and an ultrafast sintering technique: Electrical Resistance Sintering (ERS). Comparison of the microstructures obtained will allow to know how the physical characteristics of the processing influence phase formation and final properties. |
