Effect of B4C on the Microstructure and Mechanical Properties of As-Cast TiB+TiC/TC4 Composites

doi:10.1007/s40195-014-0035-5

Abstract

Abstract:

Different additions of B₄C were introduced into TC4 to alter the microstructure and mechanical properties. The morphologies of reinforcements are related to the solidification paths. The refinement of lamellar spacing λ is based on the precipitation pattern of β-phases. Microhardness, compression elastic modulus (E_c), and elastic modulus of the matrix (E_m) appear non-linear relationships with B₄C additions. Due to the refinement of lamellar spacing with Hall–Petch-type relationships, and the solution strengthening of C on the α + β matrix, the effect of reinforcements on the mechanical properties will be more efficient when the additions of B₄C are no more than 0.19 wt%. When the additions of B₄C are more than 0.19 wt%, the efficiency will decrease.

Key words: Titanium matrix composites, Lamellar spacing λ, Microstructure, TiC, TiB, Nanoindentation
