| Description
| - This research provides an attempt to achieve uniform grain structure by recrystallization process from different hot and cold-working conditions followed by various annealing in NiMoCr alloy. The different structure would result in high temperature mechanical properties such as ductility, fatigue, and creep strength. The microstructural changes results from all tested programs were investigated by an optical microscope. The results showed the uniformity of the recrystallized structure strongly relating to the amount of reduction during hot working and period of annealing time. It was found that the uniformity of recrystallized structure increased with a higher amount of deformation and longer annealing time. Furthermore, the results illustrated that the recrystallized structure on the surface layer was finer than the interior of the sample. This could be due to the recrystallization occurring close to the specimen surface, which was influenced by a much higher degree of deformation and heat lost.

- Tento výzkum se zaměřuje na dosažení homogenní mikrostruktury slitiny NiMoCr procesem rekrystalizace z různých podmínek deformace za tepla i za studena následované různým procesem žíhání. Rozdílná mikrostruktura může mít za výsledek dobré mechanické vlastnosti za vysokých teplot, jako jsou tažnost, únavová a creepová pevnost. Mikrostrukturní změny byly zkoumány optickým mikroskopem a jsou výsledkem všech testovaných programů. Výsledky ukazují, že homogennost rekrystalizované mikrostruktury silně závisí na množství deformace během tváření za tepla a na délce žíhání. Bylo dokázáno, že homogennost rekrystalizované struktury se zvyšuje s větším stupněm deformace a delším časem žíhání. Dále výsledky naznačují, že rekrystalizovaná struktura povrchové vrstvy byla jemnější než struktura uvnitř vzorku. Toto může být způsobeno rekrystalizací nastalou v blízkosti povrchu vzorku, který je ovlivněn vyšším stupněm deformace a vyššími odvodem tepla. (cs)
