The construction of deformation-mechanism maps for ferrous alloys is described. Maps for pure iron, 316 and 304 stainless steel, and a ferritic 1 percent Cr-Mo-V steel are presented, and their use is illustrated. The maps are constructed, as far as possible, from model-based constitutive laws which have been fitted to experimental data. They attempt to combine the understanding of the fundamentals of dislocation mechanics and diffusion theory with the observation of the yielding and creep of commercial steels. In this way we retain some of the predictive power that an understanding of fundamentals permits, while giving a good description of the observed behavior of the alloys. |
