Microstructure and Mechanical Behavior

The micromechanisms of deformation and in particular the dislocation reactions have been analyzed in detail and have been discussed with respect to strength and ductility (Koss etal., 1990 Kim and Froes, 1990 Yamaguchi and Umakoshi, 1990 Froes et al., 1991 Umakoshi et al., 1993 a, b). In the DOjg structure five independent slip systems are possible (Kim and Froes, 

It is noted that one of the possible slip systems in single crystals shows an anomalous temperature dependence for the yield stress (Minonishi, 1991 Umakoshi etal., 1993b), i.e. the yield stress increases with rising temperature until a maximum is reached. Such an anomalous temperature dependence is characteristic of various in-termetallics and has been analyzed in much detail for the well-known case of Nij Al, which is discussed in Sec. 4.1.2. The findings for NijAl, however, do not apply
