摘要

Abstract

In-situ

pre-decorated different content of TiB

particle reinforced 2024 Al matrix composites (

TiB

/2024Al composite

= 0

8 wt.%) were printed by laser powder bed fusion (LPBF). A quantitative equation was established to quantify heterogeneous nucleating potency by TiB

nanoparticles on the grain size of the LPBFed samples. Optimized mechanical properties were obtained in the as-printed 4TiB

/2024Al alloy which proved the feasibility of replacing the wrought part with the LPBFed one. This manuscript provides a method to determine the optimized content of TiB

nanoparticles to change the noncastable material to the printable one.
