Abstract

16MnR steel has been investigated experimentally and numerically to explore the microstructural change in the crack tip zone. It was found that, under an applied load, carbon atoms near the crack tip diffused in the gradient direction of stress, strain and temperature fields into the crack tip zone, gathered in the zone and phase change took place forming the secondary pearlite structure, on which the crack propagated.
