Download or read book Grain Boundary Sliding in Ultra fine Grained 5083 Aluminium Alloy written by Ming-Je Sung and published by . This book was released on 2013 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative measurement and analysis of grain boundary sliding in Ultra-fine grained 5083 Aluminium by AFM was conducted at 623K. The grain size of as received cryomilled Ultra-fine Grained Aluminium was characterized by AFM and TEM, and the average was founded to be about 300nm. Ion beam polishing / etching technology was used to reveal grain boundaries for AFM characterization. The vertical offset of grain boundary sliding was measured by comparing pre-defoemation and post-deformation AFM images. By analyzing these measurements, the contribution of grain boundary sliding to the total strain was estimated as 22% - 52% at a strain rate of 10-4 /sec -5x10-2/sec. It was demonstrated that the relatively low value of the contribution of grain boundary sliding to the total strain is most likely the result of testing under experimental condition that favor the dominance of region I ( low stress) of the sigmoidal behavior characterizing high strain rate superplasticity, which was previously reported.

This book was released on 2010 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present study, quantitative measurement and analysis for grain boundary sliding (GBS) in ultrafine-grained (UFG) 5083 Al using atomic force microscopy (AFM) has been conducted. As-received cryomilled UFG 5083 Al was characterized by transmission electron microscopy (TEM), and scanning electron microscopy (SEM) . As a result of the examination, the average grain size was determined as ~ 300 nm. Ion beam polishing & etching technique was used to reveal grain boundaries in the alloy for AFM characterization. A comparison between the average grain size of annealed samples measured by TEM and that obtained by AFM showed that the average grain size of the latter technique agrees well with that of the former technique. The vertical offset of GBS was measured by comparing pre-deformation and post-deformation AFM images. As a result, the contribution of GBS to the total tensile strain in 5083 Al was estimated as 22% at a strain rate of 10-4 s-1 and a temperature of 473 K. The relatively low value of the contribution of GBS to the total strain is most likely the result of testing the material under experimental conditions that favor the dominance of region I (low-stress region) of the sigmoidal behavior characterizing superplasticity.
