Tuning the microstructure and mechanical properties of additive manufactured aluminum matrix composites by cold spray

Cold spray (CS) has significant technical advantages in additive manufacturing of aluminum matrix composites. In this study, Al with different content of Al2O3 composite deposits was successfully produced by CS. The effect of Al2O3 content and heat treatment temperature on the microstructure and mechanical properties of the deposits was comprehensively studied. The results show that as the content of Al2O3 increases, the hardness, Ultimate...
