Introduction of “diffusion in solid” into Scheil–Gulliver model resulted in a drastic reduction in the cracking susceptibility (i.e., reduction in the magnitude of |d T/d f 1/2 S|) and a shift in the maximum |d T/d f 1/2 S| to higher concentrations of solute. In order to elucidate this divergence, solidification cracking susceptibility from the steepness of the solidification curves, specifically |d T/d f 1/2 S|, as the fraction solidified nears 1 towards complete solidification, was calculated via Scheil–Gulliver model as a function of solute concentration in simple binary Al-Si, Al-Mg, and Al-Cu systems. However, processing of many commercial Al-alloys by LPBF remains challenging due to the formation of solidification cracking, although they are labelled castable or weldable. ![]() ![]() Laser powder bed fusion (LPBF) has demonstrated its unique ability to produce customized, complex engineering components.
