    Numerical simulation on the multiphase flow and reoxidation of the molten steel in a two-strand tundish during ladle change

    A 3D mathematical model was proposed to investigate the molten steel–slag–air multiphase flow in a two-strand slab continuous casting (CC) tundish during ladle change. The study focused on the exposure of the ...

    Neutron diffraction and phase evolution of the mechanically alloyed intermetallic compound ζ-FeZn13

    High-energy ball milling with subsequent annealing is used to synthesize the intermetallic compound ζ-FeZn13. The mechanically alloyed phase in the as-milled state is determined to be nonequilibrium, or metastabl...
