Orientation of nanocrystals in rapidly solidified Al-based alloys and its correlation to the compound-forming tendency of alloys

Microstructure characterization of rapidly solidified Al–Fe–Cr–Ce alloy by positron annihilation spectroscopy

“…The levels of undercooling achievable at such high cooling rates lead to significant and often potentially beneficial modifications of rapidly solidified microstructures compared to those produced under conventional conditions [1]. The rapid solidification causes an increase in the solubility of alloying elements in the matrix, a refinement of the microstructure and an improvement of material homogeneity.…”

Structure and properties of nanostructured aluminum A413.1 produced by melt spinning compared with ingot microstructure

“…In terms of rapid solidification, enhanced solid solubility of alloying elements, considerable increase in chemical homogeneity and formation of metastable crystalline and metallic glasses have been reported as well [1][2][3][4][5].…”

Effect of Process Parameters on Laser Powder Bed Fusion of Al-Sn Miscibility Gap Alloy

“…The following solidification with high cooling rate entraps low-melting phase in the network created by primary nucleation of highmelting one. Several techniques are reported in literature to obtain fast solidification of Al-Sn based alloys, like laser alloying (Zhai et al [4], Makhatha et al [10]), high-velocity oxyfuel (Marrocco et al [11]), and melt spinning (Lucchetta et al [12], Kim and Cantor [13], Zhang W. et al [14], and Zhang Z. et al [15]). Confalonieri and Gariboldi [16] studied the possibility of using laser powder bed fusion (LPBF) as rapid solidification process in which a blend of Al and Sn powders is locally melted through a pulse laser.…”
