V and W had detrimental effects on grain refinement. The behavior was similar with Ta, but to a lesser extent. However, Ti1-xZrxB2 had a grain refinement minimum around x=0.65-0.70. Overall, Ti and Zr provide the best grain refinement, both as Ti1-xMxB2 and Al3Ti1-xMx. Ti1-xMxB2 grain refiners offered no advantage over Al3Ti1-xMx. It was found that grain size varied with x, M and the sum of Ti+M. In this work, a high throughput method have been used to produce Al-2wt%Cu alloys with additions of Ti1-xM(Zr,Ta,V,W)xB2, Al3Ti1-xM(Zr,V)x or AlB2 grain refiners for 0.1

The findings of X-ray microscopy (XRM) analyses on LPBF specimens and in-situ differential fast scanning calorimetry (DFSC) analyses on single powder particles at LPBF-like high heating and cooling rates reveal decreasing crack volumes with decreasing solidification supercooling.

The present work investigates the effects of varying addition contents of CaB6 nanoparticles (0.0–2.0 wt%) on the alloys' solidification behavior as well as the specimens’ solidification-crack volume, microstructure, and mechanical properties. The addition of a sufficient amount of the potent heterogeneous nucleating agent CaB6 enables the fabrication of crack-free specimens from the solidification-crack susceptible high-strength 2024 (Al–Cu–Mg) aluminum (Al) alloy using laser powder bed fusion (LPBF).
