Abstract

To address the demand for high-temperature lightweight structural materials in aerospace, titanium matrix composites (TMCs) have attracted extensive attention. A novel pelleted heterostructure Ti1100-TiB composite (PHS-TMC) has been proposed, which achieves an ultimate tensile strength and tensile ductility enhancement of approximately 10% and 40%, respectively, compared to the homostructured Ti1100-TiB composite (HMS-TMC) at high temperatures . Actually, the coarse-grained region possesses superior high-temperature plastic deformation ability to coordinate the deformation of the fine-grained region to enhance the work-hardening capacity. This research provides insights into achieving superior strength-ductility synergy of TMCs at high temperatures.
