dc.description.abstract | The correlations of the microstructural factors with the tensile and crack tip opening displacement (CTOD) properties at -20 and -60 degrees C for three kinds of API linepipe steels were investigated. The C steel composed mainly of small-sized acicular ferrite exhibited excellent tensile and CTOD properties. On the other hand, the A and B steels with large-sized polygonal ferrite or granular bainite exhibited low CTOD properties at -60 degrees C. The effective grain size was inversely proportional to the CTOD value at low temperatures. In the A and B steels, the values of the plastic deformation area and the CTOD were low because the crack tips of the steels opened under a low maximum force due to the fracture mode of the unstable brittle crack extension behavior. In the C steel, however, the values of the plastic deformation area and the CTOD were high because the crack tip of the steel opened under a high maximum force due to the fracture mode of almost fully plastic behavior. The C steel showed the widest stretch zone and the highest CTOD value. The CTOD values and the portions of post elongation in the A and B steels decreased with decreasing test temperature. | - |
