High temperature deformation and fracture mechanisms in a nickel aluminide alloy

  • Kang Chung

The mechanisms that control high temperature deformation and fracture were studied in a nickel aluminide(Ni3Al) alloy that was thermo-mechanically treated to produce a non-porous microstructure. Comparisons of data corresponding to the dendritic morphology with that for the equiaxed grain structures indicated that the dendritic morphology results in a significantly lower creep rates as well as substantially greater times to rupture. From the microstructural observations, isolated interdendritic cavitation in th absence of grain boundary sliding was found to lead to rupture lifetime that are longer than those observed for the other microstructures.
