Special Issue Information
Dear Colleagues,
Materials science research has a strong impact on technological advancement and pushing manufacturing towards industry 4.0 and the possible space era. Materials with versatile electronic, magnetic, and mechanical functionalities in extreme environments are in high demand; hence, the discovery of new materials and/or combinations of existing materials is essential. Conventional alloys generally relying on the presence of a single principal element and various minor constituents have been pushed toward their functional limits. Nearly two decades ago, new groups of materials, known as high-entropy alloys (HEA) and medium-entropy alloys, were introduced. The utilization of a large percentage of multiple principal constituent elements created unique alloying and composition optimization processes, in which materials with functionalities surpassing existing alloys could be realized. According to Boltzmann’s simple entropy formula, if the configurations in an alloy all have the same weighting or energy, the configurational entropy is given as S=kBLn(R), where S is the total configurational entropy, kB is the Boltzmann constant, and R is the number of possible configurations. It was suggested that the presence of multiple elements (in earlier studies, five or more elements were used) with near equiatomic ratios would maximize the configurational entropy to the degree required to overcome compound formation enthalpy and subsequently stabilize the solid solution state with relatively simple crystal structures. Recent experimental and theoretical studies revealed the importance of the low enthalpy of the mixing, in addition to the high-entropy criterion. The low-enthalpy criterion is very attractive, as it offers a wider compositional range that comprises alloys with fewer elements, as well as alloy structures that deviate from equiatomic compositions. Such progress led to the renaming of this group of alloys; nowadays, multicomponent alloy systems terminology is preferred over high-entropy alloy terminology. Such alloying techniques have had a significant impact on the design of new alloys with superior electronic, magnetic, mechanical, and electrochemical functionalities.
This Special Issue will bring together recent experimental and theoretical developments in the field of multicomponent alloys, including, but not limited to, alloy design and the electrical and magnetic, mechanical, and electrochemical properties of these alloys in bulk, single-crystal, and thin-film form.
