Understanding the effect of reinforcements on microstructure evolution and strengthening mechanism in aluminum matrix is crucial for development of good performance aluminum matrix composites (AMCs) prepared by laser additive manufacturing (LAM). In this work, the roles of submicron-TiB2 particles i...
