Deformation Mechanism of Fine-Grained Superplasticity in Metallic Materials Expected from the Phenomenological Constitutive Equation
The superplastic behavior of fine-grained metals is well described by the deformation model in which grain boundary sliding (GBS) is accommodated by slip. This slip accommodation process involves the sequential steps of glide and climb, with climb assumed to be the ratecontrolling process. The climb distance during GBS is often considered to be on the order of grain size in the conventional the...
متن کاملUltrafine-Grained Metals
Ultrafine-grained (UFG) metallic materials are at the cutting edge of modern materials science as they exhibit outstanding properties which make them very interesting for prospective structural or functional engineering applications. Due to the progress in severe plastic deformation techniques during the last decade, ultrafine-grained microstructures are no longer only restricted to easy to def...
متن کاملSpecial Grain Boundaries in Ultrafine-Grained Tungsten
Field ion microscopy and computer simulation were used for the study of an atomic structure high-angle grain boundary in hard-drawn ultrafine-grained tungsten wire. These boundaries with special misorientations are beyond the scope of the coincident site lattice model. It was demonstrated that the special non-coincident grain boundaries are the plane-matching boundaries, and rigid-body displace...
متن کاملSurface damage in ultrafine and multimodal grained tungsten materials induced by low energy helium irradiation
SEMmicrograph of a multimodal grained tungsten material after being irradiated with 200 eV He ions at 950 C and a fluence of 1 10 m 2 showing the detachment and the nanostructuring of the small grains as well as pore formation on top of the nanostructures. The sample was etched before irradiation for better imaging of the grain boundaries. a r t i c l e i n f o
متن کاملMicrostructure of Ultrafine- Grained Metals after Ecap
This paper was aimed at verification of functionality of the ECAP technology at extrusion of the copper, alluminium alloys and steel. Experiments were made on equipment, which is demonstrated in the Fig 1. Deformation forces were measured during extrusion, resistance to deformation was calculated and deformation speed was determined approximately. Analysis of structure was made with use of ligh...
