Faceting of Twin Grain Boundaries in High-Purity Copper Subjected to High Pressure Torsion
The microstructure of high-purity 5N5 copper processed by high pressure torsion (HPT) is studied. Close to the top and bottom surfaces of HPT disk, the 2-10 μm-thick ultrafine-grained layers with equiaxial grains and grain size of about 150 nm are formed. This grain size is typical for HPT of copper and its alloys. However, the remaining bulk layer in the HPT disk contained mainly elongated intersecting twins with high aspect ratio and length of up to 1 μm. These twin grain boundaries (GBs) aredoi:10.5445/ir/1000100003 fatcat:5lxh5gst3rg25bkqfjbjk2mrfu
