摘要：
This paper systematically investigated the effect of solution and artificial aging heat treatments on the microstructural evolution and mechanical properties of TiB/Ti-6Al-4V composites in situ fabricated by selective laser melting. The results showed that the fully martensite microstructure with TiB clusters of the as-built samples was transformed into lamellar & alpha;+& beta; microstructure with TiB strips after solution heat treatment. With increasing the temperature, the & alpha; laths and TiB particles coarsened and the & beta; volume fraction increased. After aging heat treatment, & beta; volume fraction decreased and TiB had no obvious changes. A superior combination of the yield strength of (1146.8 & PLUSMN;28.2) MPa and even higher plasticity and ultimate compressive strength ((1680.1 & PLUSMN;18.3) MPa) than the as-built ones was obtained by solution heat treatment at 1000 & DEG;C + water quenching and aging at 600 & DEG;C for 6 h + air cooling.
