Abstract
The heterogenization of plastic deformation in shear bands creates a p ossibility to control the spatial distribution of precipitated phases by their preferential nucleation and growth on structural defects insi de the shear bands. Basing on such a concept an experiment has been ca rried out on lead brass to check the possibility of the redistribution of alpha and beta phases from a chaotic to ordered, composite-like fo rm. The results reveal a significant effect of shear banding at high t emperature on the spatial distribution of phases in the alloy. The yie ld point of material with composite-like structure is almost by 40% gr eater when compared with that of material treated in the conventional way, while ductility remains the same.
