Special Issue Information

Dear Colleagues,

Metal matrix composites are materials based on metals, alloys and intermetallics, reinforced by particles or fibers. Due to their designability, metal matrix composites combine the best properties of the metal matrix and ceramic reinforcements, such as good ductility and toughness, a high modulus, and strength. Hence, metal matrix composites have developed into a new type of material, which has been widely applied in many fields, such as military, aerospace, and automotive fields, etc.

Thus, publications about the fabrication, characterization and testing of metal (e.g., Al, Ti, Fe, NiTi and TiAl et al.) matrix composites reinforced with different phases (e.g., fibers, particles, whiskers) are encouraged to be submitted for publication in this Special Issue. Furthermore, the composite manufacturing process (e.g., powder metallurgy, hot-pressed sintering, infiltration, stir casting) and strengthening mechanism analysis (e.g., fine-grain strengthening, second-phase strengthening) will also be fully considered. It is expected that, through this Special Issue, some guidance will be offered on the fabrication, investigation and application of the metal matrix composites.

It is my pleasure to invite you to submit manuscripts to this Special Issue. Full papers, communications, and reviews are all welcome.

In general, FeCrAl alloys are faced with the separation of the high-chromium solid solution into α and α′ phases. For the Fe-25Cr-5Al-RE alloy, it is imperative to investigate the structure and morphology and their effect on the alloy’s mechanical properties. In this paper, XRD is used to reveal the presence of α and α′ phases. Based on XRD data, Rietveld refinement combined with quantitative texture analysis is carried out to determine the lattice constants and the harmonic coefficients. Then, SEM and TEM techniques are employed to provide an insight into the α′ phase and its morphology. The percentage total elongation at fracture is anti-correlated with the lattice of the α′ phase and the generalized harmonic coefficients C41. Full article

This study aimed to investigate the effects of the addition of Bi and Zn on the mechanical properties of Sn-Ag-Cu lead-free alloy frequently used as a soldering material in the semiconductor packaging process. To reduce the Ag content of the commercial alloy SAC305 (Sn-3Ag-0.5Cu) by 1 wt.%, Bi and Zn were admixed in different ratios and the changes in mechanical and electrical properties were analyzed. Compared to the SAC305 alloy, electrical conductivity and elongation at break decreased while tensile strength increased following the addition of the two elements. In particular, upon the addition of 1 wt.% Bi, the tensile strength increased to a maximum of 43.7 MPa, whereas the tensile strength was 31.9 MPa in the alloy with 1 wt.% Zn. Differential thermal analysis and scanning electron microscopy revealed that the changes in physical properties can be ascribed to a reduction in the activation energy required for formation intermetallic compound when Bi was added, and the refinement of the structure due to a decrease in undercooling degree when Zn was added. When Bi and Zn were added at the same time, each characteristic for the change in the microstructure was applied in a complex manner, but the effect on the change of the physical properties worked independently.

This paper targets developing new low-cost sustainable materials. To achieve this objective, aluminum was utilized as base material for metal matrix nanocomposites (MMNC). Three routes of advanced manufacturing techniques were designed and implemented. Flake powder metallurgy as a reliable method to synthesis nanocomposites powder was employed. By reinforcing aluminium with SiC and using a similar amount of both constitutes, three metal matrix nanocomposites (MMNCs) with different properties were produced. The ball milled powder were characterized using filed emission scanning electron microscope (FE-SEM) to analyze the morphology of the powder. Different investigations and analysis were conducted on the produced samples. These include X-ray diffraction (XRD) analysis, density and porosity, mechanical properties, and frictional performance. The obtained results include relative density, Young’s modulus, compressive yield strength, elongation, toughness, hardness, coefficient of friction, and specific wear rate. Achieving superior mechanical and tribological performance is evident from these results. This is accredited to the homogeneity of the reinforcement dispersion within the aluminum matrix.
