Abstract

Pronounced crystallographic texture, characteristic for the parts manufactured by selective laser melting, is eliminated upon addition of TiB₂ microparticles to Al-12Si powder. Due to the wetting of TiB₂ ceramic by Al-12Si melt and a high inoculation efficiency, a homogeneous microstructure consisting of fine equiaxed grains with random crystallographic orientation is formed by SLM processing of the Al-12Si/TiB₂ powder mixture. The Al-12Si/TiB₂ samples exhibit enhanced yield strength and microhardness, compared to the TiB₂-free Al-12Si samples produced at the same SLM conditions.
