| Description
| - Creep strength and microstructure of Ti-48Al-2Cr-2Nb-1B and Ti-46Al-2W-0.5Si-(0.7B) alloys are compared. The influence of a prior-to-creep heat treatment on the initial microstructure is investigated. The isothermally forged and heat treated Ti-48Al-2Cr-2Nb-1B alloy was tested in nearly lamellar and equiaxed modifications while the cast and HIP-ped Ti-46Al-2W-0.5Si alloy was either nearly lamellar or duplex before creep. All these microstructural variants were crept in tension at 1023 K and at different applied stresses. Experimental results obtained in the present study suggest that, in spite of creep strength variations resulting from the different microstructural states, the Ti-46Al-2W-0.5Si alloy performs better than the Ti-48Al-2Cr-2Nb-1B alloy. Transmission electron microscopy analysis provided evidence that W- and Si-rich phases that precipitate both, on the lamellar boundaries and inside the gamma grains, contribute to the superior creep strength of the Ti-46Al-2W-0.5Si alloy

- Práce porovnává creepovou pevnost a mikrostrukturu slitin Ti-48Al-2Cr-2Nb-1B a Ti-46Al-2W-0.5Si-(0.7B). Je analyzován vliv tepelného zpracování před creepem na výchozí mikrostrukturu. Kovaná a následně tepelně zpracovaná slitina Ti-48Al-2Cr-2Nb-1B byla testována ve dvou mikrostrukturních modifikacích, a to jako rovnoosá zrna a plně lamelární zrna. Slitina Ti-46Al-2W-0.5Si měla před creepem duplexní mikrostrukturu. Všechny tyto mikrostrukturní varianty byly podrobeny creepu v tahu při 1023 K a různých hladinách aplikovaného napětí. Výsledky experimentů prokázaly, že nehledě ke změnám pevnosti souvisejícím s mikrostrukturním stavem, slitina Ti-46Al-2W-0.5Si vykazuje vyšší creepovou pevnost ve srovnání se slitinou Ti-48Al-2Cr-2Nb-1B. Transmisní elektronová mikroskopie přispěla k objasnění uvedených efektů. Fáze bohaté na W a Si stabilizují lamelární mikrostrukturu slitiny Ti-46Al-2W-0.5Si a tím přispívají k její vynikající creepové pevnosti (cs)
