摘 要：<正> In this paper,the dislocation distribution struc-ture in deformed metal is discussed.The flow stressof material for the heterogeneous dislocation distri-bution which tends to the flow stress for the homo-geneous dislocation distribution in the limiting caseis derived.The causes and the effects of the longrange internal stresses are discussed.The totaldeformation energy of material system is obtainedand the trend of evolution of dislocation distribu-tion in deformed metals is discussed simultaneously.No micromechanisms of dislocations are involvedin the discussion,therefore the theory developed inthis paper is universal.
