Plastic deformation, vacancy diffusion, and vacancy delocalization in bcc 3He.
The plastic deformation of bee 3He crystals has been studied near the melting curve, in the temperature range 0.65 K :::; T:::; 1.17 K, and for strain rates, E, from 2X 10to 2X 10sec-I. The resulting relations between strain rate and stress, at a given temperature, are accounted for in terms of dislocation climb and vacancy diffusion in the solid He. The temperature dependence of the strain rat...
متن کاملDeformation-driven diffusion and plastic flow in amorphous granular pillars.
We report a combined experimental and simulation study of deformation-induced diffusion in compacted quasi-two-dimensional amorphous granular pillars, in which thermal fluctuations play a negligible role. The pillars, consisting of bidisperse cylindrical acetal plastic particles standing upright on a substrate, are deformed uniaxially and quasistatically by a rigid bar moving at a constant spee...
متن کاملMeasuring Plastic Deformation
This article describes the current level of understanding of dislocation plasticity in thin films and small structures in which the film or structure dimension plays an important role. Experimental observations of the deformation behavior of thin films, including mechanical testing as well as electron microscopy studies, will be discussed in light of theoretical models and dislocation simulatio...
متن کاملPredicting Plastic Deformation and Work Hardening during V- Band Formation
V-Band Clamps are manufactured using a cold roll forming process consisting of six passes which plastically deform an initially flat strip by bending to produce the band’s V-section. In this paper a new method of validating numerically predicted plastic deformation in a cold formed metal strip is presented. Tensile testing of samples of the band’s material was used to obtain a direct link betwe...
متن کاملMeasurement of Superconducting Transition Curves of Lead during Plastic Deformation
The plastic enhancement effect is used as a new method for studying the transition curves of plastically deformed superconductors. Strainand temperature dependent field penetration below Hc is obser6ed. The phenomenon of enhanced plasticity in superconductors has been studied intensively in the last years /I/. In all experimental investigations of this effect the sample must be deformed alterna...
