摘要：
<正> If a plastic metal is subjected to permanent deformation, then due to the changesoccurring in crystallographic lattice the metal alters its properties. Experiments carried outby many investigators prove that the ultimate strength, the yield strength and hardness in-crease with the deformation, on the other hand, the elongation decreases, the impact valueand reduction of area also change. Fig. 1 illustrates the effect of cold work by drawingon the mechanical properties of an armco iron according to W. Broniewski and J. Krol.
