Abstract

). Thus, ∆ S conf for equimolar alloys with 3, 5, 6, 9, and 13 elements equal to 1.10 R , 1.61 R , 1.79 R , 2.20 R , and 2.57 R , respectively. In addition, if the formation enthalpies of two strong intermetallic compounds ( e.g. , NiAl and TiAl) are divided by their respective melting points, the resulting ∆ S conf , 1.38 R and 2.06 R , belong to the same range as the entropy changes of mixing in a system with more than five elements [1]. This evidences that the tendency to ters such as laser power, scanning speed, and powder­feed rate are analysed for their influences on the microstructure and mechanical properties of the final pro­ duct. The post­processing techniques for additive­manufactured HEAs are conside­ red. The importance of steps such as heat treatment, surface finishing, and machin­ ing in achieving the desired material properties and dimensional accuracy in AM­ produced HEA components is underlined. Overviewing the HEAs, their application in AM processes, the influence of process parameters, and post­processing consi­ derations, this work can act as a useful source of information for researchers on the way to amendment of the understanding and implementation of AM in the HEAs.

期刊介绍: The review journal Uspehi Fiziki Metallov (abbreviated key-title: Usp. Fiz. Met.) was founded in 2000. In 2018, the journal officially obtained parallel title Progress in Physics of Metals (abbreviated title — Prog. Phys. Met.). The journal publishes articles (that has not been published nowhere earlier and are not being considered for publication elsewhere) comprising reviews of experimental and theoretical results in physics and technology of metals, alloys, compounds, and materials that possess metallic properties; reviews on monographs, information about conferences, seminars; data on the history of metal physics; advertising of new technologies, materials and devices. Scope of the Journal: Electronic Structure, Electrical, Magnetic and Optical Properties; Interactions of Radiation and Particles with Solids and Liquids; Structure and Properties of Amorphous Solids and Liquids; Defects and Dynamics of Crystal Structure; Mechanical, Thermal and Kinetic Properties; Phase Equilibria and Transformations; Interphase Boundaries, Metal Surfaces and Films; Structure and Properties of Nanoscale and Mesoscopic Materials; Treatment of Metallic Materials and Its Effects on Microstructure and Properties.
