| Abstract Scope |
Titanium alloys have attracted attention for aerospace and transportation applications due to their high specific strength and corrosion resistance. However, since titanium alloys exhibit low elastic modulus and poor high-temperature resistance compared to conventional alloys, titanium matrix composites (TMCs) reinforced with ceramic reinforcements have emerged as a promising alternative. In this study, we fabricated Ti(W)-TiC composites by reacting WC particles with pure titanium melts through arc melting. The high temperature of the process promoted the chemical reaction between the titanium melts and WC particles, which resulted in the in situ formation of thermodynamically stable TiC dispersed within the matrix. By varying the WC content up to 70 vol.%, the evolution of TiC morphology and the distribution of W in the matrix were investigated. The relationship between the resulting microstructure and mechanical properties was evaluated through compression tests, and the strategy for designing strong and tough titanium matrix composites was discussed. |
