Experiments and calculations have shown that the notch sensitivity of the ductile aluminide Ni{sub 3}Al(B) is related to the suppression of plastic flow by the triaxial state of tensile stress produced by the notch. Cracks initiate at the tip of the notch, where stress and strain are concentrated, and then propagate intergranularly when the degree of triaxiality exceeds a critical level.
