Studies on softening kinetics of low manganese steel microalloyed with niobium for high-strength sour service ERW pipe

The aim of the paper is to develop a quantitative understanding of the recrystallization behavior of low manganese - 0.10 percent niobium line pipe steel for sour service application. Experimental results on recrystallization behavior of low manganese - 0.10 percent niobium steels from WUMSI and stress relaxation tests are analyzed using a physically based model for time evolution of strain induced precipitation of NbC and its interaction with …
