Abstract: Abstract With a nominal composition of Nb-18Si-24Ti-2Cr-2Al (at%), pre-alloyed Nb-Si based alloy powders were fabricated by plasma rotating electrode processing (PREP). The phases and microstructures of the pre-alloyed powders subjected to spark plasma sintering (SPS)… read more here.

Abstract: The influence of natural convection on lamellar eutectic growth was determined by a comprehensive phase-field lattice-Boltzmann study for Al-Cu and CBr_{4}-C_{2}Cl_{6} eutectic alloys. The mass differences resulting from concentration differences led to the fluid flow… read more here.
