摘要：
Two-dimensional distributions of microstructural characteristics of austenite () around the Luders band in medium-Mn transformation-induced plasticity (TRIP) steel were revealed by in situ high-energy X-ray diffraction. Luders band propagation leads to significant changes in the volume fraction and lattice strains of austenite. The evolution of the lattice strain of -311 accords well with the true yield behavior model and is used to estimate the angle of the Luders band front with respect to the tensile axis. The modified Williamson-Hall analysis shows that the dislocation density in austenite increased from 7x10(14)m(-2) to 1.5x10(15)m(-2) after Luders band propagation. IMPACT STATEMENTThis in situ high-energy X-ray diffraction study unravels two-dimensional distribution of microstructural evolution during Luders band propagation in medium-Mn TRIP steels.
