Book Description
The results of observations and investigations of a new phenomenon -- changes in the macroscopic characteristics of the plastic deformation of metals and alloys at a superconducting transition -- are systematised. In these works it is shown for the first time that the electronic drag of dislocations accompanying low-temperature deformation is effective. The main experimental features of the phenomenon -- the dependences of the characteristics of the change in plasticity at a superconducting transition on the stress, deformation, temperature, deformation rate, and concentration of the alloying element in the superconductor -- and results indicating a correlation between the characteristics of the effect and the superconducting properties are presented. Experiments clarifying the mechanisms of the phenomenon are analysed. A brief exposition of the theoretical investigations of the electronic drag of dislocations in metals in the normal and superconducting states and the influence of a superconducting transition on the plasticity is given. The theoretical results are compared with the experimental results. Examples of the application of the effect as a new method for investigating the physical mechanisms of low-temperature plastic deformation are presented. The applied aspects of the phenomenon are discussed separately.

Book Description
The last few decades have seen considerable progress in the development of high-performance metals and alloys that have microstructures and plastic behaviors with a high level of complexity. Ultrafine-grain materials, metallic glasses, gradient microstructures, etc., have clearly been gaining the attention of researchers and are gaining a place in the industry. Concurrently, the self-organized nature of plastic deformation, leading to complex behaviors on mesoscopic scales even in pure metals with highly symmetric lattices, has been generally recognized. Such progress has demanded the development of sophisticated experimental techniques (in situ TEM, digital image correlation, nano-indentation, etc.), advanced multiscale modeling (molecular dynamics, discrete dislocation dynamics, strain gradient models, etc.), and methods of analysis of the observed and simulated behaviors from the viewpoint of self-organization, with an aim of filling gaps between the elementary atomic-scale mechanisms and the scale of a laboratory sample. The current research has evolved in two main areas. First, new approaches to old questions and traditional model materials allow for a deeper understanding of physical mechanisms. Second, a better understanding of the process-microstructure-property links provides a basis for the elaboration of new materials and processing routes, as well as for the creation of powerful computer models that are able to predict the behavior of complex materials. This Special Issue aims at presenting examples of such recent progress and trends in the plasticity of metals and alloys.

Book Description
In several industrial fields (such as automotive, steelmaking, aerospace, and fire protection systems) metals need to withstand a combination of cyclic loadings and high temperatures. In this condition, they usually exhibit an amount—more or less pronounced—of plastic deformation, often accompanied by creep or stress-relaxation phenomena. Plastic deformation under the action of cyclic loadings may cause fatigue cracks to appear, eventually leading to failures after a few cycles. In estimating the material strength under such loading conditions, the high-temperature material behavior needs to be considered against cyclic loading and creep, the experimental strength to isothermal/non-isothermal cyclic loadings and, not least of all, the choice and experimental calibration of numerical material models and the selection of the most comprehensive design approach. This book is a series of recent scientific contributions addressing several topics in the field of experimental characterization and physical-based modeling of material behavior and design methods against high-temperature loadings, with emphasis on the correlation between microstructure and strength. Several material types are considered, from stainless steel, aluminum alloys, Ni-based superalloys, spheroidal graphite iron, and copper alloys. The quality of scientific contributions in this book can assist scholars and scientists with their research in the field of metal plasticity, creep, and low-cycle fatigue.

Book Description
Superplasticity is shown to be a universal phenomenon in materials ranging from metals and intermetallics to ceramics. Superplastic deformation facilitates the production of materials with specifically chosen properties. This is illustrated using the examples of Mg-, Al-, and Ti-based commercial alloys, steels, and superalloys. Some of the strenghts of this book are: the broad range of materials studied, the reduction of scientific results to a form suitable for the practitioner, a profound physical analysis of the phenomenon, a new approach to superplastic treatment as a kind of strain-heat treatment, the presentation of new data on superplastic flow and on production techniques of micro- and submicrocrystalline structures.
