| Description
| - Creep, microstructure and failure of the squeeze cast MgY3Nd2Zn1Mn1 alloy were investigated. The tensile creep tests were performed at 300°C and constant load in the stress range 30-80 MPa. The minimum creep rate eps.-min , as a function of the stress, follows a power law with the exponent n = 5.9 at 30-70 MPa. The time to fracture tf is also a power function of the stress with an exponent m = -4.4. The modified Monkman-Grant relation is valid. Microstructure development during creep exposure of the MgY3Nd2Zn1Mn1 alloy suggests the low stacking fault energy as the main creep controlling factor. The alloy is superior to the WE43 alloy both in time to fracture and in the minimum creep rate about one and two orders of magnitude, respectively. Both the mean value of the modified Monkman-Grant constant and its scatter correspond to the model of constrained growth of cavities along dendrite boundaries.

- Creep, mikrostruktura a porušení slitiny MgY3Nd2Zn1Mn1 lité metodou squeezecasting byly vyšetřovány. Tahové creepové zkoušky byly provedeny na 300°C v rozmezí vnějších napětí 30 až 80 MPa. Minimální rychlost creepu eps.-min je funkcí napětí a řídí se exponenciální závislostí o exponentu n = 5.9 v rozmezí napětí 30 až 70 MPa. Doba do lomu je rovněž exponenciální funkcí napětí s exponentem m = -4.4. Modifikovaný Monkman-Grantův vztah v platnosti. Vývoj mikrostruktury slitiny MgY3Nd2Zn1Mn1 naznačuje, že nízká energie vrstevné chyby je hlavním faktorem řídícím creep. Tato slitina je má řádově vyšší dobu do lomu až o dva řády nižší minimální rychlost creepu, čímž překonává slitinu WE43. Hodnota konstanty z modifikovaného Monkman-Grantova vztahu i hodnota její odchylky odpovídají modelu stísněného růstu kavit podél dendritických hranic. (cs)
