Microstructure, mechanical properties and post-weld heat treatments of dissimilar laser-welded Ti2AlNb/Ti60 sheet

Mechanical and Microstructural Investigations of the Laser Welding of Different Zinc-Coated Steels

“…Standard tensile characteristics include yield stress (YS), ultimate tensile strength (UTS), and percent over elongation at break (ductility). The YS, UTS, and elongation to fracture of the BM as well as TWB were evaluated [19][20][21][22][23]. In the calculation of the stress-strain diagram of the TWB samples, the thickness of the thinner sheet was considered as the initial thickness.…”

Effect of pre-heating and post-weld heat treatment on structure and mechanical properties of laser beam-welded Ti2AlNb-based joints

“…Since the β-phase is metastable and undergoes the β→O and/or β→α 2 transformations at high temperatures [15], post-weld heat treatment (PWHT) can stabilize the structure and properties of the joints [10]. PWHT usually consists of quenching from the β phase field [16] and aging at temperatures in the range of 800-840 • C, resulting in the O-phase precipitation [17].…”
