Strength Estimation of a Ti Alloy Matrix Composite Reinforced by TiC Particles

Abstract:

The microstructure of a titanium alloy matrix composite with 10 vol % TiC particles was observed. Based on strengtheningmechanism of a multiphase alloy, various microstructural strengthening behaviours in the composite are estimated. The Mises yieldcriterion is used for estamating the combined modulus strengthening and matrix strengthening. The predlcted yield strength is comPared to the observed yield strength of the composite.

Key words:TiC particle strengthening, Ti matrix composite, yield strength, modulus strengthening, matrix strengthening,
