Ebsd study on grain boundary characteristics in fine-grained Al alloys

The microstructural characteristics of ultrafine-grained nickel

“…However, both of these parameters play a significant role in determining the bulk properties of the materials [27,28]. Some information has become available recently on the grain boundary misorientation distributions after ECAP of pure Al and Al alloys [29][30][31][32][33][34][35][36][37][38][39], ECAP of pure Cu [38,40,41], ECAP and HPT of pure nickel [5,42] and ECAP of pure Zr [43]. Although the results on pure Ni are fairly limited [42], the experimental data suggest that HPT produces a microstructure with a higher fraction of high-angle grain boundaries than ECAP.…”

A comparison of grain size determination by light microscopy and EBSD analysis

“…

The characterization and measurement of grain structures is of great importance to materials scientists because not only does grain size strongly affect the mechanical properties, but it also has an influence on physical properties, surface properties and [3,4,5,6,7]. In most cases, it is assumed that the microstructure features, especially the grain size obtained from light microscopy and EBSD are the same.

“…Recent developments in the use of electron backscattered diffraction (EBSD) have made it an excellent tool for quantitative metallography. In addition to grain size determination, there are a number of important microstructural parameters available from EBSD not obtainable from conventional methods of grain characterization, in particular parameters relating to the grain orientations and boundary characters [3,4,5,6,7]. In most cases, it is assumed that the microstructure features, especially the grain size obtained from light microscopy and EBSD are the same.…”

Microtexture based analysis of surface asperity flattening behavior of annealed aluminum alloy in uniaxial planar compression

“…Deformed grains possess lower internal misorientations and stored energy. Furthermore, deformation grains have large low-angle grain boundary (LAGB) populations and small deformation twin fractions (3) [31]. Owing to the low deformation temperature (room temperature), the influence of recovering is not significant.…”
