    Ultrafine grained copper by equal channel angular extrusion (ECAE) processing

  • Original language description

    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 imagingmicroscopy (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 whichwas elongated in the shearing direction. Corresponding OIM data illustrated an inhomogeneous microstructure in which bandlike features were also aligned with the shearing direction

    Jemnozrnná struktura mědi po aplikaci ecae procesu

  • Czech description

    Měď o vysoké čistotě (99,99%) byla metodou ECAE protlačována při pokojové teplotě matrici s úhlem kanálů 105?. Vzorky byly analyzovány transmisní elektronovou mikroskopii (TEM). Analýza byla provedena po prvním, čtvrtém a 12 průchodu matricí. Mezi jednotlivými průchody bylo vzorky otáčeno o 90? 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, kdejednotlivé vrstvy jsou rovněž seřazeny ve směru smykové deformace.
