Abstract
The bulk Ti3(Al1−x,Gax)C2 (x including 0, 0.1, 0.2, 0.3, and 0.4) materials have been successfully synthesized by hot pressed sintering method using Ti, Al, TiC, and Ga as raw materials. The crystalline phases and microcosmic morphology were characterized by X-ray diffractometry and scanning electron microscope, etc. The analysis and simulation for the XRD patterns of Ti3(Al1−x,Gax)C2 are used to quantitatively study the effect of solid-solution on lattice parameters, and the results show that the reduced c-lattice parameter (especially the c/a ratio) of Ti3(Al,Ga)C2 solid solutions could improve the coordination and symmetry of the intergranular deformation, indicating improved mechanical properties of the solid solutions. The Vickers hardness, flexural strength, and fracture toughness of Ti3(Al0.7,Ga0.3)C2 are 7.87 GPa, 403.17 MPa, and 7.03 MPa·m1/2, respectively. The hardening and strengthening mechanism are investigated in detail. The damage modes of the fracture surfaces and energy-consuming mechanisms in these materials are also discussed.
