Plastic-strain localization of fcc, bcc, and hcp single crystalline and poly crystalline materials is investigated in different stages in the loading curve under active uniaxial tension. Localization patterns are found to be of an ordered character and can be classified into four types, each corresponding to a certain stage in the loading curve. The regularities observed are interpreted in terms of self-organization in open systems. It is shown that all types of localization patterns can be treated as autowaves of plastic flow. The wave parameters are analyzed and the fundamental difference from the well-known waves of plasticity under shock loading is demonstrated.
