抄録: | Effects of ternary additions on the microstructure and thermal stability of directionally-solidified MoSi[2]/Mo[5]Si[3] eutectic composites have been studied for twelve different elements (Ti, V, Cr, Fe, Co, Ni, Nb, Ta, W, Ir, B and C) paying special attention to the variation of lattice misfits and interface segregation behavior with ternary additions. Among six elements (type-1: Ti, V, Cr, Nb, Ta and W) with a relatively high solubility in MoSi[2] and Mo[5]Si[3], Ta and W are found to be beneficial to microstructure refinement. All other six ternary elements (type-2: Fe, Co, Ni, Ir, B and C) with a negligibly low solubility in MoSi[2] and Mo[5]Si[3] exhibit a strong tendency to segregate on MoSi[2]/Mo[5]Si[3] interfaces, resulting in both microstructure refinement and the modification of the interface morphology. |
