Cerium dioxide has a comparatively lower Ce4+/Ce3+redox pair,which leaves abundant oxygen vacancies on oxide lattice,also making incorporation of foreign ion and subsequent applications feasible and convenient.In this work,a series of cerium-yttrium mixed

For better performances of Ni-based catalysts at low temperatures,Ni/SiC catalyst doped with a little amount of additive La was successfully prepared.The catalytic CO methanation activity tests showed that 3%La-Ni/SiC catalyst was excellent at a low react
Recent studies suggested that the interactions between particles can induce aggregative nucleation and growth processes beyond those predicted by the traditional LaMer model of nanoparticle formation,but their nucleation and growth processes are still unc
In this work,CuFe2O4 hollow microspheres assembled with nanosheets(CuFe2O4 HMANs)were synthesized using a solvothermal method followed by an annealing treatment.The effects of annealing temperature on microstructure,chemical composition and gas sensing ch
Microstructures and tensile properties of a newβhigh-strength titanium alloy Ti-5321(Ti-5 Al-3 Mo-3 V-2 Zr-2 Cr-1 Nb-1 Fe)were investigated in this study.Four microstructures,including equiaxed microstructure(EM),bimodal microstructure(BM),basket-weave mi
A short process of Inconel 625 alloy tube was developed to solve the problems of the traditional extrusion process,and particular attention was paid on the hot deformation behavior of the as-cast Inconel 625 alloy.The hot compression experiments were perf
It is important to understand the correlation between grain morphology and intervariant boundaries of theαphase after heat treatment belowβtransus of the electron beam melted(EBMed)Ti-6 Al-4 V alloy.Scanning electron microscopy(SEM)and electron backscatte
The controlled preparation of hexagonal tung-sten trioxide(h-WO3)nanostructures was achieved by adjusting the pH of the precursor solution.The effect of the pH
Microstructures and mechanical properties of Mg-4.5 Y-2.5 Nd-1.0 Gd-0.5 Zr-xZn(x=0,0.5,1.0,and 1.5;wt%)alloys under as-cast and peak-aged states were investigated in this work.The results indicate that the intermetallic phase components are closely depend
Rejuvenation heat treatments can restore the microstructures and mechanical properties of the degraded turbine blades in gas turbine engines.Herein we analyze the effects of rejuvenation heat treatments on the microstructural characteristics and mechanica
