| Description
| - Technika Pravoúhlého protlačování (ECAP), která zahrnuje jednoduché velké deformace během průchodů skrz dva křížící se kanály, byla aplikovaná na AZ 91 Mg, aby byla získána ultrajemnozrná mikrostruktura. Pro zjištění napětí a deformační síly byla použita počítačová simulace. Teplota ECAP byla kontrolována se snížením počtem průchodů pro získání jemného zrna. Čtyři protlačení byly řízeny při 250ºC, zatímco páté protlačování bylo řízeno při 180ºC. Degrese zjemnění zrna a homogenita velikosti zrna distribuce se zvýšením počtu průchodů. FEM simulace byla pužita na slitiny AZ91 praktickými testy. Hlavní důvod pro tyto simulace je možnost využití v praxi. Experimentální výsledky souhlasily s tím co bylo získáno z mnoha analýz uskutečněné na základě metody konečných prvků (FEM). Tyto výsledky mohou být použity v dalším vývoji metod SPD. (cs)
- Equal channel angular pressing (ECAP) technique, which involves a simple large sudar deformation during passage through two intersecting channels, was applied to the AZ91 Mg to obtain an ultrafinegrained microstructure. For the stress and strain intensity investigation, these was used computer simulation. ECAP temperature was controlled to decrease with pass numer for obtaining finer grains. Four pressing were conducted at 250ºC, while the fifth pressing was conducted at 180ºC. The degrese of grain refinement and homogenity of grain-size distribution increased with pass numer.FEM simulation was examined on AZ91 alloys by practical tests. Head reason for make this simulations is the posibility of exercise in praxe. The experimenatl result agreed well with that obtained from numerical analyse carried out based on the finite element metod(FEM). This results can be used in next development of SPD methods.
