Designing high-temperature oxidation-resistant titanium matrix composites via directed energy deposition-based additive manufacturing

Composite material development via laser-based additive manufacturing offers many exciting advantages to manufacturers; however, a significant challenge exists in our understanding of process-property relationships for these novel materials. Herein we investigate the effect of input processing param...
