Description	Cílem práce je stanovení změny elasto-plastických vlastností hořčíkové slitiny AZ91 na teplotě, včetně hodnocení lomových charakteristik. Byl pozorován interkrystalický charakter lomu a stanoveno maximum plasticity při vyšší teplotě v důsledku částečného výskytu transkryslalického houževnatého lomu. (cs) Objective of this work consisted in determination of changes of elastic-plastic properties of magnesium alloy AZ91 in dependence on temperature, including investigation of fracture characteristics. It was confirmed that during heating at chosen temperatures there occurs partial dissolution of minority phases. Homogenisation of microstructure is, however, accompanied by simultaneous forming of inter-granular non-integrities, which is unfavourable from the viewpoint of strength and plastic properties, especially at higher temperatures. Failure occurs practically at all temperatures basically by inter-crystalline splitting along the boundaries of original dendrites. At temperature testing near melting point of alloy the interdendrite areas melting were observed.
