As a candidate material for hydrogen separation,Yb-doped SrCeO3 has attracted increasing attention in recent decades.In the present study,Yb-doped SrCe0.9Yb0.1O3-α ceramics were prepared by the dry pressing and sintering approach,with the microstructure e
Incorporation of hydroxyapatite in crosslinked gelatin/chitosan/poly(vinyl alcohol) hybrids utilizin
The crosslinked gelatin/chitosan/poly(vinyl alcohol)/hydroxyapatite (GEL/CTS/PVA/HAp,GCPH) sponges were fabricated by a freeze-drying method to yield the reinforced composite sponges with proper features.The porosity value and pore size of the crosslinked
Microstructure evolution and corresponding tensile properties of Ti-5Al-5Mo-5V-1Cr-1Fe alloy control
The influence of heat treatments on the microstructures and mechanical properties of the selective laser melting manufactured AlSi10Mg alloy modified with Sc was systematically investigated.The results showed that the addition of Sc element introduced pri
Ameliorating mechanical properties and reducing anisotropy of as-extruded Mg-1.0Sn-0.5Ca alloy via A
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
Characteristic investigation of trilayered Cu/Al8011/Al1060 composite:Interface morphology,microstru
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

Microstructure and elevated-temperature mechanical properties of dispersoid-strengthened Al-Mg-Si-Mn
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
