Article Preview

A magnetic technique was applied to examine cyclic deformation behavior and deformation damage in ordered FeAl and Ni3(Al,Ti) single crystals. The fatigue lifetime of FeAl was evaluated by an abrupt increase in spontaneous magnetization. The morphology of γ precipitates in Ni3(Al,Ti) during annealing and deformation was examined by changes in spontaneous magnetization and coercive force.
