Titanium carbide – Titanium boride composites by self propagating high temperature synthesis approach: Influence of zirconia additives on the mechanical properties

This work presents the fabrication of high-dense titanium carbide – titanium boride (TiC-TiB2) composites by self-propagating high temperature synthesis (SHS) under-load methodology. The influence of particle size of boron carbide (B4C) and the amount of titanium (Ti) on the TiC-TiB2 composites prop...
