Bulk texture evolution of Cu–Nb nanolamellar composites during accumulative roll bonding

High-strength and thermally stable bulk nanolayered composites due to twin-induced interfaces

“…To increase the coverage of the pole figures, the sample was rotated to angles of o ¼ 0°, 67.5°and 90°. The MAUD 32 program was used to perform a Rietveld refinement on the 150 neutron diffraction patterns. The Rietveld refinement made use of an E-WIMV method with a 10°-resolution in order to simultaneously fit all the diffraction patterns and determine an orientation distribution function (ODF).…”

“…In this work, nanolamellar Cu/Nb composites in the form of bulk sheet with high interfacial content are fabricated via accumulative roll bonding (ARB) 32 (see Supplementary Fig. S1).…”

Optimum high temperature strength of two-dimensional nanocomposites

“…NMMs are 2D nanostructured thin films or sheets that contain alternating layers of dissimilar metals with individual thicknesses far below 100 nm. 3,4 Consequently, NMMs are comprised of an unusually high density of bimetal interfaces. Experiments have shown that these interface-rich composites are several times stronger and structurally more stable after exposure to high-temperature and/or radiation environments than their constituents.…”

The Suppression of Instabilities via Biphase Interfaces During Bulk Fabrication of Nanograined Zr

“…[7][8][9] Realizing these outstanding material properties in structural applications requires methods of fabricating nanomaterials in the bulk form. Over the past few decades, severe plastic deformation (SPD) techniques, such as wire drawing, [10,11] high-pressure torsion (HPT), [12][13][14][15] equal channel angular pressing (ECAP), [16,17] and accumulative roll bonding (ARB), [18][19][20][21][22][23] have been employed to successfully make nanomaterials and nanolayered materials. The last two processes, ECAP and ARB, can potentially produce nanomaterials in sheets and rods in both sizes and quantities suitable for structural applications.…”
