Microstructural evolution, strengthening and toughening mechanisms of AZ80 composite sheet reinforced by TiB2 with fiber-like distribution

Z. Y. Xu et al.

Summary: The in-situ TiB2/AZ80 composite was prepared by a simple casting method and hot-rolling, which showed improved strength and toughness. The TiB2 particles can refine the grains of AZ80 alloy and promote recrystallization through PSN effect, leading to a transformation in recrystallization mode and distribution characteristics of TiB2 particle clusters. The composite sheet mainly gains strength from fine grain strengthening and thermal mismatch strengthening, while internal toughening mechanisms include texture weakening and the proliferation of more dislocations induced by the PSN effect. External toughening mechanisms are attributed to bending and deflection of cracks resulting from fiber-like particle distribution characteristics.

Microstructure evolution and tensile properties of as-rolled TiB/TA15 composites with network microstructure

Shuai Wang et al.

Summary: TiB whiskers reinforced Ti-6.5Al-2Zr-1Mo-1V (TA15) composites with the addition of silicon element and different TiB volume fractions were successfully fabricated and rolled in the alpha+beta region, showing improved room-temperature properties. The increase in strength was attributed to grain refining of the matrix, directional distribution of TiB whiskers, and hinder of silicides, while the enhancement in ductility was due to increasing matrix connectivity, grain refining, and bimodal microstructure DRX behavior. At high temperatures, the tensile strengths increased significantly after rolling, attributed to directional distribution of TiB whiskers, grain refining, and larger silicides. The highest strengths achieved were 820 MPa at 600°C and 698 MPa at 650°C.
