| Description
| - Tvářecí technologie založené na využití velkých plastických deformací (SPD) jako je ECAP mohou být použity i pro neželezné materialy jako vhodné technologie pro modifikaci jejich vlastností. Bylo ověřeno, že zvýšená teplota při procesu poskytuje vhodné podmínky pro získání jemnozrných materiálů. Tento příspěvek byl zaměřen na experimentální ověření funkčnosti ECAP technologie u pamětových materiálů na bázi Ni-Ti. Krom zmíněného pojednává take o kontinuálních změnách rezistivity jako funkce teploty u zpracovávaných slitin. Jako další bylo měřeno deformační a následné tepelné zpracování při těchto teplotách. Zpracovávané vzorky byly kruhového průřezu o průměru 12 mm a délky 50 mm. Ni-Ti slitiny byly protlačeny dvoustupňově a sice při teplotě T1= 773 K a T2= 723 K. Během procesu byly zaznamenávány deformační síly, deformační odpor a rychlost deformace stanoveny. Po každém průchodu byla zjištěna akumulace deformačního zpevnění (až = 745 Mpa). Mikrostruktura závisela na experimentálních podmínkách, obzvl (cs)
- SPD techniques as ECAP proces can be used for non-forrous metals like Ti, Cu, Mg, Al, etc. to change its properties. It was approved that elvated temperature provide a succefully conditions for the fine grained final materials obtaining. This paper was aimed on verification of functionality of the ECAP technology at extrusion of the Ni-Ti alloys. This article deals with method of continuous change of resistivity as function of temperature of Ni-Ti alloys, and with influence of deformation and subsequent heat treatment at these temperatures. Circular cross-section of original samples was 12 mm in diameter and their length was 50 mm. For the samples of Ni-Ti alloys was used the two-stage pressing, when the samples were extruded at temperature of approx. T1 = 773 K and T2 = 723 K. Deformation forces were measured during extrusion, resistance to deformation was calculated and deformation speed was approximately determined. After individual passes there was occurred an accumulation of deformation strengt
