Good mechanical properties and excellent pitting corrosion resistance for 0.8 mm-thick 27Cr-4Mo-2Ni super-ferritic stainless steels produced by one-stage cold rolling or two-stage cold rolling together with intermediate annealing processes are achieved. The microstructural evolution, precipitation and their effects on mechanical properties and corrosion resistance are investigated in terms of optical...
Transition-metal oxides are highly sought as alternative anode materials for rechargeable lithium-ion batteries (LIBs) owing to their high theoretical capacity. However, the large volume variation of active materials during cycling leads to poor cycle life, which hinders commercial applications. In this work, we prepared cobalt oxide/copper oxide/reduced graphene oxide (CoO/CuO/rGO) ternary nanocomposites...
Equal channel angular pressing (ECAP) was performed on extruded pure Mg, which was clad with a drilled pure Fe coat through an ECAP die to produce a pure Mg sample without obvious cracks at room temperature. After one-pass ECAP, the grain size decreased because of basal slip activation during the dynamic plastic deformation but the microstructure became inhomogeneous. The deformed texture was less...
Three-layered 5052Al/AZ31Mg/5052Al (5052/AZ31/5052) clad sheets were fabricated by four-pass rolling and annealed under different conditions. Under the optimal annealing condition, homogeneous and equiaxial grains with an average AZ31 grain size of 5.24 µm were obtained and the maximum values of ultimate tensile strength and elongation of the clad sheet reached 230 MPa and 18%, respectively. Electron...
Three-layered 5052/AZ31/5052 clad sheets with maximum rolling reductions of 33% and 48% were prepared, using single-pass hot rolling followed by thermal annealing at 200°C for 1 h. The evolutions of microstructures and textures were analyzed. The experimental results show that the AZ31 layer exhibited a typical deformation microstructure with rolling-induced twins. The AZ31 layer with the 33% rolling...
Steel/Cu/Al laminated sheets were fabricated by two-pass hot rolling to improve the mechanical properties of steel/Al sheets. The bonding properties and deformability of the steel/Cu/Al sheets were studied. Steel/Al and steel/Cu/Al samples were rolled at 350°C for 15 min with the first-pass reduction of 40%, and then heated at 600°C for 5 min with different reductions. It was found that the steel/Cu/Al...
