Abstract
16MnR steel has been investigated experimentally and numerically to ex plore the microstructural change in the crack tip zone. It was found t hat, under an applied load, carbon atoms near the crack tip diffused i n 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 propagate d.
