Fatigue Behaviour and Fracture Toughness of Fe3Al and FeAl Iron Aluminides
Result description
This paper presents a study of fatigue and fracture behaviour of two Fe3Al based intermetallic alloys with different Zr content - (at%) Fe-31.5Al-3.5Cr-0.25Zr-0.2C and Fe-29.5Al-2.3Cr-0.63Zr-0.2C - and one FeAl based alloy - Fe-40Al-1C. The fracture toughness tests were performed on Half inch Compact Tension (CT) specimens of thickness B=12.5mm and width W=25mm, machined in perpendicular to the rolling direction. The tests were performed at the constant crosshead speed of 0.25 mm/min according to the ASTM E 1820 standard. The experiments were performed at 20, 200, 400, and 600°C.

Únavové chování a lomová houževnatost aluminidů železa Fe3Al a FeAl.
Czech description
Článek se zabývá únavovým a lomovým chováním třech slitin (at%) Fe-31.5Al-3.5Cr-0.25Zr-0.2C, Fe-29.5Al-2.3Cr-0.63Zr-0.2C a Fe-40Al-1C. Zkoušky lomové houževnatosti byly provedeny na půlpalcových CT tělesech tloušťky B=12.5mm a šířky W=25mm, vyrobených kolmo ke směru válcování. Vlastní zkoušky byly provedeny při konstantní rychlosti příčníku 0.25 mm-min podle normy ASTM E 1820, a to při teplotách 20, 200, 400 a 600°C
