Summary: In this study, a TiAl matrix composite reinforced by submicro/nano-Ti2AlC was fabricated using pre-alloyed Ti-48Al-2Cr-2Nb powders and graphene nanosheets as raw materials via spark plasma sintering and subsequent heat-treatment. The microstructure characterization results showed that the submicro-Ti2AlC and nano-Ti2AlC had coherent atomic correspondence with the full lamellar TiAl matrix. Furthermore, the Ti2AlC/TiAl composite exhibited an excellent balance relationship between room-temperature compression strength (-2171 ± 3 MPa) and fracture strain (-31 ± 1%).

Summary: The FCC structured CoCrFeMnNi high entropy alloy (HEA) has attracted attention due to its excellent ductility and strain hardening ability. A new strategy called harmonic structure (HS) was developed to achieve high strength and ductility. HS consists of soft coarse and hard fine grains formed by controlled mechanical milling time. The hardness of HS HEAs increased with increasing distance from center to surface regions due to a reduction in grain size. Compared to homogeneous HEAs, HS HEAs exhibited increased yield strength and enhanced strain hardening ability.

Summary: This paper innovatively describes the calculation method of overall stress of the pipe after reel-laying and clarifies the influence of plastic deformation on the performance strengthening. The accuracy of the theoretical results is verified through comparative tests. The results show that plastic deformation improves the performance of the pipe material, enhancing its tensile, compression, bending, and torsion resistance. The maximum potential increase is theoretically 45.16%, and experimental measurements have shown conformity with theoretical values.

Summary: Controlling the morphology of kink bands can effectively improve the strength and ductility of aluminum alloys. The microstructure plays a significant role in the formation of kink bands and the mechanical properties of the material. By varying the microstructural control, the role of the deformation kink band can be changed from a fracture mode to a deformation mode, leading to a large increase in yield stress while maintaining ductility.

Summary: Local canning compression is applied to equiatomic NiTi shape memory alloy with complete B19' martensite, leading to different grain sizes after annealing at 300, 450 and 600 degrees C. The highest elastic limit is achieved under annealing at 300 degrees C, while the highest yield stress and good plasticity are observed under annealing at 450 degrees C. Annealing at 600 degrees C results in a relatively low yield stress but still higher than the as-received NiTi SMA, with high plasticity as well.
