        abstract = {In-situ pre-decorated different content of TiB2 particle reinforced 2024 Al matrix composites (xTiB\_\{2\}/2024Al composite, x = 0, 1, 2, 4, 6, 8 wt.\%) were printed by laser powder bed fusion (LPBF). A quantitative equation was established to quantify heterogeneous nucleating potency by TiB2 nanoparticles on the grain size of the LPBFed samples. Optimized mechanical properties were obtained in the as-printed 4TiB\_\{2\}/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\_\{2\} nanoparticles to change the noncastable material to the printable one. This manuscript provides a method to determine the optimized TiB2 content to change the noncastable material to the printable one, and can potentially guide the introduction of many other nanoparticles.},
