Abstract: It is known that some internal defects exist in metal materials. Preliminary attempt to relate dislocation evolution with metal rheological forming was done. By the attempt, it is learned that the evolution of dislocation density ρ(x, y, t) is essentially the change ofnindependent internal variables qα(α=1,2,…, n)with material. The preliminary research in theory and experiments showed that dislocations piling-up could be avoided. One can improve the internal microstructure and mechanical properties of products by rheological forming method.
