Effect of strontium and cooling rate upon eutectic temperatures of A319 aluminum alloy [PDF]

, 2004
DTA analysis was used to investigate the solidification reactions of alloy A319 with either 12 or 136 ppm of Sr added. Strontium does not affect primary solidification of (Al) dendrites but modifies the kinetics of the (Al)–Si eutectic. The effects of Sr

Solidification in soft-core fluids: disordered solids from fast solidification fronts [PDF]

, 2014
Using dynamical density functional theory we calculate the speed of solidification fronts advancing into a quenched two-dimensional model fluid of soft-core particles. We find that solidification fronts can advance via two different mechanisms, depending
