| Description
| - Compressive creep tests of a magnesium alloy and its fibre composite (with 27 vol.% of Saffil fibres) were performed in temperature interval from 423 to 523 K in order to judge the strengthening influence of fibres and to analyse possibilities of an explanation of physical bases of the creep strain. Both materials were prepared by squeeze casting. From stress and temperature dependence of the minimum creep rates, activation parameters of creep, i.e., the apparent activation energy and the stress sensitivity parameter of creep rate, were evaluated and compared with the purpose to suggest possible mechanisms of creep deformation. In both materials investigated, the stress sensitivity parameters and the activations energies are relatively high and cannot be directly attributed to any creep mechanism. No threshold behaviour was observed in the stress dependence of the creep rates in both materials. A dependence of the creep behaviour on the orientation of composite specimens is presented.

- Byly provedeny tlakové creepové zkoušky hořčíkové slitiny AS21 a kompozitu na její bázi s 27 obj. % Saffilových vláken v intervalu teplot 423 až 523 K s cílem posoudit zpevňující vliv vláken a analyzovat možnosti objasnit fyzikální podstatu creepové deformace. Oba materiály byly připraveny technikou tlakového lití. Z napěťových a teplotních závislostí minimální rychlosti creepu byly odvozeny a porovnány aktivační parametry creepu, tj. zdánlivá aktivační energie a parametr napěťové citlivosti, z nichž lze usuzovat o možných mechanismech creepu. V obou materiálech parametry napěťové citlivosti a aktivační energie dosahují vysokých hodnot a nelze je přímo přiřadit nějakému creepovému mechanismu. ani u jednoho z materiálů nebylo v napěťových závislostech pozorováno prahové chování. Je presentována závislost creepového chování kompozitů na orientaci zkušebních vzorků. (cs)
