Abstract
This work investigates the strengthening mechanism of the in-situ TiB/TiC reinforced Ti1100 composites manufactured by casting technique. Tensile experiments are conducted on five types of in-situ TiB/TiC reinforced titanium composites with different mixtures of reinforced phases. Mechanical properties of Young’s modules, ultimate tensile strength and tensile fracture strain are analysied. With the partial least squares regression method, the reinforcing effects of TiB and TiC on the composites’ performances are further studied. Corresponding numerical modeling, the simulations are as well processed with the finite element (FE) program ABAQUS. In conclusions, the numerical simulations are in good agreements with the experimental results. With different mixtures of reinforced phases, the mechanical properties of the in-situ TiB/TiC reinforced titanium composites are different. Detailed strengthening mechanism of in-situ TiB/TiC reinforcements in the composites is also highlighted.
