Fatigue properties (fatigue life and fatigue limit) of three different carbon
content steel alloys, CK35, Y8 and Y10 were investigated at RT and 300 ºC fatigue
testing. The main contribution of this work was to find the influence of carbon
content on high temperature fatigue properties. It was found that the fatigue life in
both cases, RT and 300 ºC, decreased dramatically via increasing carbon content
from 0.35% to 0.8% but at 1% carbon content the fatigue life was increased. The
fatigue limit and its reduction percentage took the same trend of the fatigue life.
