It is generally difficult to obtain good weld formation and excellent properties in super thick titanium alloy joints via conventional electron beam welding (EBW) methods due to the fact that the melt pool flow becomes more unstable as the plate thic

It is difficult to prepare large-area bulk ultrafine-grained (UFGed) titanium alloys with uniform structure via multi-pass overlapping friction stir processing (MP-FSP) due to the low thermal conductivity and poor flow deformation ability of titanium

It is usually very difficult for achieving deep penetration in titanium alloy thick plates by conventional laser beam welding (LBW) under the atmospheric environment, since the laser beam energy is easily dissipated in air. In this study, LBW in a lo

In this study, the ultrafine-grained (UFG) Cu–5Mn alloys were prepared by friction stir processing (FSP) to investigate the influence of short-range ordering (SRO) on the tensile deformation behavior. Due to the dynamic recrystallization, the unifo

For the precipitation-strengthened aluminum alloys such as Al–Mg–Si alloys, the friction stir welded (FSW) joints produced with T6-treated plates usually exhibit obvious softening in the heat-affected zones (HAZ), significantly reducing the joint

How the quenching and partitioning (Q&P) steel with an ultrahigh strength (>1 GPa) behaves during the welding process is a considerable issue for its practical application, but the systematical evaluation on the welding behavior of this new steel has
