Optimising the transformation and yield to ultimate strength ratio of Nb-Ti micro-alloyed low carbon line pipe steels through alloy and microstructural control
Thinner walled (about 6 mm thickness) line pipe steels for smaller diameter pipelines tend to have a relatively high ratio of yield strength to ultimate tensile strength (YS/UTS) of 0.93 or higher. This study focused on the effect of the microstructures, prior deformation in the austenite, cooling r...
