    The Effect of Boron on Microhardness in Ni3 Al Polycrystals

    In a recent MRS symposium, the effect of boron on grain boundary hardness (GBH) in Ni3Al was reported. Addition of 0.2 at.% of boron decreased the GBH in all three sets of alloys tested (24, 25, and 26 at.% Al). ...

    Mössbauer study of melt-spun Sm20Fe70Ti10 alloy

    The rapidly queoching samples of Sm20Fe70Ti10 were prepared by melt spinning. The coercivities of crystallized ribbons were found to vary with the spinning velocity. The value of coercivity obtained was 3.2kOe, w...

    Alloy softening in Ni3Al polycrystals

    The alloying effect of boron on localized deformation in Ni3Al polycrystals containing 24–26 at% AI was studied using microhardness indentation. Alloy softening was observed both along the grain boundaries and in...

    Grain Boundary Softening in Boron-Doped Ni3Al

    The effect of 0.2 at.% boron on grain boundary hardness in Ni3Al containing 24 to 26 at.% Al was studied. Normal grain boundary hardening was observed in all alloys with and without boron. However, the addition o...
