Alloy System

1 Introduction
Over the past decade, a new class of materials called multi-principal element alloys
(MPEAs) or high-entropy alloys (HEAs) or complex concentrated alloys (CCAs)
has received significant research attention. Such alloys usually contain from 5 to 13
elements in equiatomic or close to equiatomic concentrations [1]. The correct choice
of the number of components and their concentrations makes it possible to obtain an
alloy with high mixing entropy, the value of which is preserved both in the melt and
after solidification. Simple solid solutions of substitution with face-centered or bodycentered cubic crystal lattices are usually formed during the crystallization of such
multicomponent alloys because of their high mixing entropy. On the other hand, it is
possible to obtain the HEAs with a structure in which intermetallic compounds with
high hardness values (Laves phases, σ phase) will be combined with a simple solid
solution characterized by high ductility [1]. Many HEAs possess unique properties,
such as wear resistance, resistance to corrosion and oxidation, radiation resistance,
high hardness, and strength [1–6]. It should also be noted the superior biocompatibility demonstrated by some HEAs [5]. So, the HEAs may find use as materials for
nuclear reactors applications, medicine, electronics devices, mechanical equipment,
rocket casings, and engines, etc.
In contrast to HEAs, another type of modern material, the so-called metallic
glass (MG) contains only one, occasionally two principal elements. The HEAs and
MGs were explored separately until the amorphous HEAs have been successfully
synthesized [1]. Such alloys were called high-entropy metallic glasses (HE-MGs).
The development of HE-MGs alloys was the basis for new methods of development
