Small punch creep of Fe-Al-Cr alloy with Ce addition and its relation to uniaxial creep tests

Popis výsledku v původním jazyce

Creep behaviour of the alloy based on intermetallic compound Fe3Al with additions of 2.6 at.% chromium and 0.02 at.% cerium was studied at temperatures from 500 to 800 degrees C by small punch testing with a constant force. The dependences of the minimum deflection rate and the time to rupture on the applied force follow similar dependences obtained in uniaxial creep tests of the same alloy. The results of small punch tests can be explained by the existence of different crystal lattices occurring at different temperatures. It is shown that the force applied in the small punch test can be successfully converted into the equivalent applied stress using the empirical formula suggested by the new European standard for small punch testing. The minimum deflection rate can be converted into the minimum creep strain rate as well. The improvement of the latter conversion based on the Monkman-Grant relationship is proposed.
