Results of experiments involving various monotonic and cyclic deformation paths and annealing treatments are described. The results show that a state variable theory for constitutive behavior must be based on several independent parameters. Correlations which show that different mechanical responses may depend on the same state variables are discussed. Transmission electron microscopy (TEM) characterizations of the microstructures developed during the tests are reported. Some correlations between microstructure and mechanical behavior are shown, but other cases are reported where no correlation can be found.
