<i>In Situ</i> Formation of Ti Matrix Composites Reinforced Nanometric TiC by Powder Metallurgy Technique

Abstract

In-situ formation of nanometric TiC reinforcements based on Ti matrix composites were researched by a novel preparation method, which including glucose polymers coating and powder metallurgy. The results showed that TiC nanoparticles were homogeneously distributed in Ti matrix, and the as-sintered Ti-TiC composites displayed excellent compressive properties which ultimate compressive strength was 2500 MPa, yield strength was 1450 MPa and strain to fracture was 53 %.
