TL;DR: In this paper, the 40-60% TiC x -TiB 2 /Cu composites were successfully fabricated by combustion synthesis and hot press consolidation in a Cu-Ti-B 4 C system.

TL;DR: In this article, the effect of Mn atoms on the mechanical properties of the Ti2AlC/TiAl composites was investigated by experiments and first principles calculations, and the results showed that the addition of Mn remarkably improves the ductility of the composites.

TL;DR: In this article, the average yield strength, ultimate compression strength, and fracture strain of the pure TiB 2 -Ti 2 AlC/TiAl composite fabricated with the addition of 3.5μm B 4 C particles are, respectively, 259 MPa, 174 MPa and 0.3% higher than those of pure TiAl alloy.

TL;DR: In this paper, the effect of the content of W on the hardness, compression properties and abrasive wear behavior of the composites was investigated, and the results indicated that with increasing W content from 0 to 8 W, the average sizes of the TiB 2 and TiC x N y particles decrease firstly and then keep almost constant, while the hardness and the compression strength increase firstly, and then change a little.

TL;DR: In this article, the authors presented a composite with an optimal 5-wt% Al content, which possesses the best comprehensive properties: the highest hardness (1794 Hv), the superior compression strength (376 GPa), and the fracture strain (42%), resulting in an overall increase by ~15, 28, and 45% compared with these of the composite without the Al addition, respectively.
