Special Issue Information

Dear Colleagues,

Metal matrix composites are developed to meet the increasing demand for lightweight materials with superior mechanical properties in critical industrial sectors, such as the automobile industry and aerospace. In the past decade, attributed to mature design theories, advanced fabrication methods, and characterization techniques, the research and application of metal matrix composites have greatly advanced. Recent development in multi-scale hierarchical and bio-inspired design principles make strong and tough metal matrix composites possible to obtain. The development of nano-materials and advanced ceramics provides more reinforcements with specific performance. The continuous progress in characterization techniques reveals the relationships among the microstructure, processing, and properties of the metal matrix composites, especially on a nano-scale level, and the sophisticated preparation methods of metal matrix composites bridge the fundamental theory and industrial application.

This Special Issue aims at covering recent progress and new developments in relationships between the microstructure and mechanical/thermo-physical properties of advanced metal matrix composites. All aspects related to the theoretical design, numerical simulation, microstructure characterization, advanced fabrication, and strengthening mechanisms are discussed. Review articles which describe the current state of the art are also welcomed.

In this research, a nitrogenized shell layer was formed on the surface of Ti powder in a high-temperature N2 environment, resulting in core–shell-structured Ti@TixN powder. Using this as a reinforcement, Ti@TixN/Al composite was successfully designed and fabricated via pressure infiltration method. The TixN layer consists of a double-layered spherical shell structure, with TiN as the outer layer and Ti2N as the inner layer. After the composite was fabricated, no intermetallic compounds between Ti and Al were observed at the interface, as the TixN layer effectively prevented the reaction between Ti and Al. The tensile strength, yield strength, and elongation of the Ti@TixN/Al composite were 173 ± 7.7 MPa, 115 ± 8.1 MPa, and 7.5 ± 0.55%, respectively. Both the strength and hardness were significantly improved compared to the pure Al matrix. Observations of the tensile fracture surface revealed severe interfacial debonding at the interface, and the reinforcement did not exhibit significant coordinated deformation with the matrix. This suggests that future research could focus on strengthening the matrix by adding alloying elements and improving the interfacial bonding to enhance the performance of the composite. Full article

Anisotropy is one of the concerns of titanium matrix composites (TMCs) due to its impact on subsequent processing and safe serving. In this work, we demonstrate that simply by using cross-rolling (CR) rather than unidirectional rolling (UDR), significant plastic anisotropy can be removed and an excellent strength–ductility combination can be achieved in a new TiB-reinforced TMC (TiB-TMC). We attribute the occurrence of plastic anisotropy after UDR to be the strong rolling-induced orientation distribution of TiB whiskers parallel to the rolling direction (RD), while the elimination of anisotropy is therefore confirmed to be caused by the loss of such an orientation relationship. The underlying mechanism is revealed as the lower stress concentration along the lateral surface of the randomly distributed whiskers and the longer paths when cracks propagate in between each whisker, in the CR-processed TiB-TMC.
