Abstract
High-entropy alloys, due to their unique characteristics and complex chemical compositions, offer promising potential for a wide range of practical applications, particularly at elevated temperatures. The continuous development of these materials is driven by ongoing research on new manufacturing methods, with a large share of in-situ alloying from elemental powders in additive manufacturing processes. In addition, their complex chemical compositions provide a variety of heat treatments application, offering opportunities for tailoring properties of HEAs. In this study, four alloys based on Mn-Fe-Co-Ni with varied additions of Ti and Al and entropy levels were produced using the Laser Powder Bed Fusion technique from elemental powders mixtures and subjected to several heat treatment routes, followed by a comparative evaluation of their microstructure, hardness and yield strength in uniaxial compression tests. It was found that in Mn-Fe-Co-Ni+5Al+5Ti, precipitation strengthening via the γ’ phase (Ni, Co)₃(Ti, Al) could be achieved through appropriate heat treatment. Importantly, the results indicate that γ’-strengthened alloys have significant potential for high-temperature applications, with compressive yield strength reaching 621 MPa after 15 min of exposure at 700 °C.
