Effects of Al addition to a Mg-Sn-Ca ternary alloy on its microstructure and tensile properties after extrusion were studied via extrusion of Mg-1.0Sn-0.5Ca-xAl (x =0,0.8,2.4 wt%) sheets and analysis of the extruded materials.The results showed that Al ad
In this work,Cu/Al8011/Al1060 trilayered composite with an ultrathin copper layer was fabricated successfully by the hybrid process of cast-rolling and hot-roll-bonding.The effects of heat treatment were investigated on the microstructure and mechanical b
The microstructure and elevated-temperature mechanical properties of dispersoid-strengthened Al-Mg-Si-Mn al-loys produced by twin roll casting (TRC) and conventional mold casting (MC) were studied.A specific heat treatment at 430 ℃ for 6 h was applied,fol
The microstructure,mechanical and magnetic properties of Zr-x (8,9,10,wt.%)Nb-4Sn alloys were investigated to obtain novel Zr-based alloy with low Young\'s modulus and magnetic susceptibility for biomedical implants.After homogenization annealing,hot fo
The dielectric performances as well as the effects of Dy3+ ions content at A sites of YMnaO5 (YMO)[x =0 (YDM0)and x =0.4 (YDM0.4)]polycrystalline samples were explored.These compounds were synthesized via sol gel method.X-Ray diffraction and Raman measure
Humanity turns to a new chapter in 2022. As proud as we are of rapid developments in economics, science, and technology, we are equally concerned about such global issues as biodiversity conservation and the global pandemic of Covid-19. The unprecedented
