Plasticity of Metals and Alloys By V. V. Pustovalov Publisher: Nova Science Publishers Number Of Pages: 131 Publication Date: 2008-10 ISBN-10 / ASIN: 1604569654 ISBN-13 / EAN: 9781604569650 Preface: 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 systematized. 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 analyzed. 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. 如果用得着，评下分，谢谢 http://ifile.it/ny8io2q/1604569654.rar [ Last edited by yantting on 2009-9-14 at 10:27 ] |
