Investigation of laser welding on butt joints of Al/steel dissimilar materials
TL;DR: In this article, a 10kW fiber laser welding system with ER4043 filler metal was used to join aluminum alloy to steel by butt joints when zinc layer was hot-dip galvanized at the steel's groove face in advance.
Journal ArticleDOI
Electrochemical and XPS studies of corrosion behavior of Ti–23Nb–0.7Ta–2Zr–O alloy in Ringer's solution
Wei Guo,Junhao Sun,J.S. Wu +2 more
TL;DR: In this article, the performance of a newly developed multifunctional β-type Ti−23Nb−0.7Ta−2Zr−O (mol%, TNTZO) alloy in Ringer's physiological solution was evaluated by open circuit potential, potentiodynamic polarization and X-ray photoelectron spectroscopy (XPS) techniques.
Journal ArticleDOI
Microstructure and properties of in-situ synthesized (Ti3Al + TiB)/Ti composites by laser cladding
TL;DR: In this paper, the microstructures of the coating were analyzed; the strengthening mechanisms of the coatings were studied; the wear and high temperature oxidation resistance were investigated and compared with those of the substrates.
Journal ArticleDOI
Effect of bevel angle on microstructure and mechanical property of Al/steel butt joint using laser welding-brazing method
TL;DR: In this article, a sound butt joint between Al and steel was obtained, with the brazing interface consisting of zinc rich regions and a Fe-Al intermetallic (IMC) layer.
Journal ArticleDOI
Role of grain size in tensile behavior in twinning-induced plasticity β Ti-20V-2Nb-2Zr alloy
TL;DR: In this paper, the role of grain size in tensile behavior in a metastable β Ti-20V-2Nb-2Zr mass % alloy was investigated.
