Description
  • Měď o vysoké čistotě (99,99%) byla metodou ECAE protlačována při pokojové teplotě matrici s úhlem kanálů 105º. Vzorky byly analyzovány transmisní elektronovou mikroskopii (TEM). Analýza byla provedena po prvním, čtvrtém a 12 průchodu matricí. Mezi jednotlivými průchody bylo vzorky otáčeno o 90º ve stejném směru (cesta Bc). Po prvním protlačení, TEM ukázala subzrnitou strukturu, která byla protažená smykovou deformací. Výsledky získané optickou mikroskopií (OIM) zobrazují nehomogenní mikrostrukturu, kde jednotlivé vrstvy jsou rovněž seřazeny ve směru smykové deformace. (cs)
  • High-purity cooper (99.99 pct) was processed by equal channel angular pressing (ECAE) at room temperature through a die with a 105 deg angle between the die channels. Samples were examined by transmission electron microscopy (TEM) and orientation imaging microscopy (OIM) methods after one, four, and 12 passes through the die. Respetitively pressed samples were rotated by 90 deg in the same sense between successive pressing operations (route Bc). After one pressing, TEM showed a subgrain structure which was elongated in the shearing direction. Corresponding OIM data illustrated an inhomogeneous microstructure in which bandlike features were also aligned with the shearing direction
