Special Issue Information

Dear Colleagues,

Metal matrix composites (MMCs) have great application potential in space technology, aerospace, electronic packaging, and the automotive industry because of their excellent mechanical and physical properties, such as high strength/modulus, wear and creep resistance, excellent damping, reduced thermal expansion, excellent electrical conductivity and thermal conductivity, etc. MMCs consist of reinforcements in the form of fibers, whiskers, or particles as well as types of matrices, such as Al, Mg, Cu, Ti, Fe, Ni, Zn, intermetallic compound matrices and others.

Nowadays, MMCs are developed toward higher strength, good ductility or toughness, and multi-functional properties in order to meet the increased social demands of their wide application. For this purpose, attempts have been focused on multi-scale and architecture design, novel fabrication methods, advanced processing/characterization techniques, and clarifying related mechanisms of MMCs.

The aim of this Special Issue is to understand the basic principles of design, processing, and application, as well as new progress and findings in the fields of advanced MMCs. The articles presented in this Special Issue will cover various topics on MMCs, including, but not limited to, the following:

  • Multi-scale and architecture design;
  • Novel fabrication methods and advanced characterization techniques;
  • Interface modification;
  • Computer modeling and simulation for architecture, interface, and service performance;
  • Corrosion, tribological, physical, and mechanical behaviors;
  • Understanding the relationship between microstructure and properties.

The first volume of this Special Issue received widespread attention from scholars and included many excellent contributions. In view of this, we would like to create a second volume to continue collecting feature papers.

It is our pleasure to invite you to submit your article to this Special Issue. We look forward to receiving your paper for the Special Issue ”Progress in Metal Matrix Composites: Design, Processing and Application (Volume II)” of the MDPI journal Materials.

Due to the low density of the green part produced by selective laser sintering (SLS), previous reports mainly improve the sample’s density through the infiltration of low-melting metals or using isostatic pressing technology. In this study, the feasibility of preparing high-density 316L stainless steel using 316L and epoxy resin E-12 as raw materials for SLS combined with debinding and sintering was investigated. The results indicated that in an argon atmosphere, high carbon and oxygen contents, along with the uneven distribution of oxygen, led to the formation of impurity phases such as metal oxides, including Cr2O3 and FeO, preventing the effective densification of the sintered samples. Hydrogen-sintered samples can achieve a high relative density exceeding 98% without losing their original design shape. This can be attributed to hydrogen’s strong reducibility (effectively reducing the carbon and oxygen contents in the samples, improving their distribution uniformity, and eliminating impurity phases) and hydrogen’s higher thermal conductivity (about 10 times that of argon, reducing temperature gradients in the sintered samples and promoting better sintering). The microstructure of the hydrogen-sintered samples consisted of equiaxed austenite and ferrite phases. The samples exhibited the highest values of tensile strength, yield strength, and elongation at 1440 °C, reaching 513.5 MPa, 187.4 MPa, and 76.1%, respectively. Full article
