Effect of Inclusions on Fatigue Strength of Heat Treated Components
Original language description
Inclusions significantly affect fatigue properties of quenched and tempered parts. Data about inclusions importance during an initiation of fatigue fractures were acquired within the frame of systematical fatigue tests carried out for fatigue propertiesverification of CrNiMo (V) steels quenched and tempered to 800 - 1000 MPa strenght. A valuable set of fatigue fractures from the high lifetime area was acquired. Carried out microfractographic analysis of these fractures allowed critically evaluate the influence of inclusions, their dimensions, character and morphology on the initiation and propagation of the fatigue fractures in the area of fatigue strenght. Comparison of inclusions size ?a? after Murakami with size determined experimentally. Limitinginfluence of small single inclusions in the structure. Initiation of secondary fatigue cracks on inclusions outside of the fracture initiation area. Danger of the fracture initiation after very high lifetime.
