Microstructure and mechanical properties of pure gold processed by equal channel angular pressing

Lattice Defects and Their Influence on the Mechanical Properties of Bulk Materials Processed by Severe Plastic Deformation

“…For instance, in pure Ag with very low SFE (19 mJ/m 2 ) the saturation value of A HAGB was 1.5 © 10 7 m ¹1 (corresponding to the minimum grain size of 200 nm) after ECAP at RT, 36) and similar values were obtained for Au, Cu and Ni with significantly higher SFE values (38,62 and 125 mJ/m 2 , respectively). 66,72,73) Very high saturation values of A HAGB (³10 8 m ¹1 ) was achieved in HPT-processed HEAs (e.g., in CoCrFeMnNi, 41) Al 0.3 CoCrFeNi, 74) CoCrFeNiMnTi 0.1 75) and AlNbTiVZr 0. 5 76) ) which corresponds to a grain size value of 2530 nm.…”

Equal Channel Angular Pressing: A Novel Technique for the Production of Ultra Fine Grained Structure in Materials– A Mini Review

“…The hardness and 0.2% proof stress from the compression tests were observed to increase only up to the fourth pass whereas the compressive strength at 40% strain kept increasing gradually with increasing the number of passes. Microstructure with low angle grain boundaries and shear bands were observed until the eighth pass and equiaxed grains with high angle grain boundaries were observed only after the twelfth pass [9]. Light alloy based composites: This so called paradox of strength and ductility is of great importance for future light weight construction materials.…”

Plastic Flow and Strain Homogeneity of an Equal Channel Angular Pressing Process Enhanced through Forward Extrusion

“…[1][2][3][4][5][6][7] ECAP is also widely used to compact powders nearer to their theoretical density [7][8][9] and to enhance the microstructure and mechanical properties of tubular materials. 5,10,11) In recent years, various modifications to the ECAP process, including rotary die ECAP, 12,13) Cross-ECAP, 14,15) and T-ECAP 16,17) have been proposed.…”
