Revealing the residual stress distribution in laser welded Eurofer97 steel by neutron diffraction and Bragg edge imaging

Studying the strengthening mechanisms and mechanical properties of dissimilar laser-welded butt joints of medium-Mn stainless steel and automotive high-strength carbon steel

“…It is well established that a post-weld heat treatment (PWHT) is applied to weldments to improve their mechanical performance, such as in terms of the tensile strength and toughness [17][18][19][20][21][22], overcome the heterogeneity in microstructures across the weld structure [23], and relieve the weld-induced residual stresses arising from rapid cooling, phase transformation in the FZ, and different thermal expansion coefficients of the BMs and weldments [2,[24][25][26][27].…”
