Special Issue Information

Dear Colleagues,

Many industries rely heavily on non-ferrous metals and alloys owing to a wide variety of their properties. Such characteristics as their light weight (Al, Mg, Ti alloys), heat and electrical conductivity (Cu), high-temperature resistance (Ni, Ti, Co, W alloys) or biocompatibility (Ti, Mg, Au) attract researchers from multidisciplinary areas to explore their potential. Ideas of new processing routes benefit better materials performance and manufacturing sustainability. Special attention is needed to establish the relationship between the designed microstructure, phase transformations, and advanced properties in order to increase the quality of existing alloys and to develop the novel non-ferrous alloys.

This Special Issue primarily considers papers focused on the relationship between microstructure, processing methods, and properties of non-ferrous metallic materials. The microstructural studies and novel material processing methods are the key points of the issue. We are inviting papers which include but are not limited to any of the following thematic areas:

  • Primary fabrication of non-ferrous metals and alloys;
  • Secondary processing and heat treatment (metal forming, phase transformations, ultrafine-grained materials, mechanical alloying);
  • Properties and modeling of technological processes;
  • Novel metallic alloys;
  • Novel processes and applications (additive manufacturing, etc.);
  • Recycling of non-ferrous metals and alloys.

Effect of Y Addition on the Microstructure and Mechanical Properties of ZM31 Alloy
Materials 2020, 13(3), 583; https://doi.org/10.3390/ma13030583 - 26 Jan 2020
Abstract
Effects of different Y contents (0, 0.3, 0.7, 1.5, 3, 5 and 10 wt.%) on the microstructure, thermal stability and mechanical properties of Mg-3Zn-1Mn (ZM31) alloys were systematically studied. The existence form and action mechanism of Y in the experimental alloys were investigated. [...] Read more.
Effects of different Y contents (0, 0.3, 0.7, 1.5, 3, 5 and 10 wt.%) on the microstructure, thermal stability and mechanical properties of Mg-3Zn-1Mn (ZM31) alloys were systematically studied. The existence form and action mechanism of Y in the experimental alloys were investigated. The results revealed that with the change of Y content, the main phases of the ZM31-xY alloys changed from Mg7Zn3 phase, I-phase, I + W-phase, W-phase, W + LPSO phase to LPSO phase. When Y content was low (≤1.5%), hot extrusion could break up the residual phases after homogenization to form dispersed fine rare-earth phase particles, and fine second phases would also precipitate in the grain, which could inhibit the grain growth. When Y content was high (≥3%), the experimental alloys were only suitable for high-temperature extrusion due to the formation of the high heat stable rare-earth LPSO phase. In addition, Y could evidently enhance the mechanical properties of the as-extruded ZM31 alloy, of which the ZM31-10Y alloy had the best mechanical properties, that is, the tensile and yield strengths are 403 MPa and 342 MPa. The high strengths of the alloys were mainly determined by fine grain strengthening, rare-earth phase strengthening and dispersion strengthening of fine α-Mn particles. Full article

Abstract: Various data on the structural and thermodynamic characteristics of polynuclear metal clusters containing atoms of aluminum and and various d-elements with the general formula AlnMm where (n+m) is 4, 5, or 6, and which can be as precursors for the formation of nanoparticles of elemental metals or intermetallic compounds, have been systematized and discussed. It has been noted that each of these metal clusters in principle is able to exist in very diverse structural modifications differing significantly among themselves in terms of the total energy and spin multiplicity of the ground state, the number of which is determined by both the specific values of n and m, and the nature of d-elements in their compositions. The presence of a very complex dynamics of changes of the individual thermodynamic characteristics of the metal clusters under consideration as well as the thermodynamic parameters of the reactions of their formation, depending on the nature of the d-element, was also ascertained.

Keywords: metal cluster; aluminum; d-element; molecular structure; thermodynamic parameters; DFT method.
