摘要: Abstract The fatigue behaviour of a medium carbon steel type 45M6 in the rolled condition containing niobium and vanadium micro-additions was compared with that same base as or quenched tempered at 500°C. Firstly, it has been shown increase yield strength level, endurance limit cyclic accommodation ability as-rolled conditions, while these characteristics remain generally lower than those treated steel. Such micro-alloyed related to its hardenability essentially induced by γ solution. Secondly, decrease low cycle life which can be attributed decohesion process interface coarse compound dispersoid precipitates observed high strain amplitudes, range higher this alloy leads an improvement untreated
