Plasticity: from Crystal Lattice to Macroscopic Phenomena
New representations concerning plasticity physics in crystals are discussed. The model of plastic flow is suggested, which can describe its main regularities. With the use of the experimental investigation, it is shown that the plastic flow localization plays the role in the evolution of plastic deformation. Obtained data are explained with the application of the principles of nonequilibrium-systems’ theory. The quasi-particle is introduced for the description of plasticity phenomenon. It is established the relation between plasticity characteristics of metals and their position in Periodic table of the elements. A new model is elaborated to address localized plastic-flow evolution in solids. The basic assumption of the proposed model is that the elementary plasticity acts evolving in the deforming of medium would generate acoustic emission pulses, which interact with the plasticity carriers and initiate new elementary shears. As found experimentally, the macrolocalization of plastic flow involves a variety of autowave processes. To address the phenomenon of localized plastic-flow autowaves, a new quasi-particle called ‘autolocalizon’ is introduced; the criterion of validity of the concept is assessed.
期刊介绍:
The review journal Uspehi Fiziki Metallov (abbreviated key-title: Usp. Fiz. Met.) was founded in 2000. In 2018, the journal officially obtained parallel title Progress in Physics of Metals (abbreviated title — Prog. Phys. Met.). The journal publishes articles (that has not been published nowhere earlier and are not being considered for publication elsewhere) comprising reviews of experimental and theoretical results in physics and technology of metals, alloys, compounds, and materials that possess metallic properties; reviews on monographs, information about conferences, seminars; data on the history of metal physics; advertising of new technologies, materials and devices. Scope of the Journal: Electronic Structure, Electrical, Magnetic and Optical Properties; Interactions of Radiation and Particles with Solids and Liquids; Structure and Properties of Amorphous Solids and Liquids; Defects and Dynamics of Crystal Structure; Mechanical, Thermal and Kinetic Properties; Phase Equilibria and Transformations; Interphase Boundaries, Metal Surfaces and Films; Structure and Properties of Nanoscale and Mesoscopic Materials; Treatment of Metallic Materials and Its Effects on Microstructure and Properties.
