The as-cast Mg-6Li-4Zn-xMn alloys were prepared and extruded at 280 ℃ with an extrusion ratio of 25∶1.The effects of Mn content on the microstructure and mechanical properties of Mg 6Li 4Zn-xMn alloys were investi-gated in this study.The XRD results show
The deformation mechanism of the fine structure composed of primary α phase (αp) and acicular secondary α phase (αs) on quasi-static mechanical properties is still not very clear.The main controversy is focused on the role of αp in the mechanical behavior
The present work is focused on the studies of the phase-structural transformations in the La3-xMgxNi9 (x 1.0,1.1 and 1.2) alloys as active materials of negative electrodes in the Nickel-Metal Hydride (Ni/MH) batteries.The phase equilibria and phase-struct
Incorporating flame retardant fillers is the most efficient way to improve the fire resistance of polylactide (PLA).However,most flame retardant fillers result in deterioration of the mechanical property of PLA so far.Therefore,to create high-performance
Fe-and Al-based thin-film metallic glass coatings (Fe44Al34Ti7N15 and Al61Ti11N28) were fabricated using magnetron co-sputtering technique,and their corrosion performances compared against wrought 316L stainless steel.The results of GI-XRD and XPS analyse
The roles of Al11Sm3 and Al2Sm phases on microstructure evolution,mechanical properties and corrosion behavior of the Mg-5Sm-xAl system was investigated.The results showed that adding Al to Mg-5Sm binary alloy brought two Al-Sm phases,Al11Sm3 and Al2Sm,wh
The microstructure,martensitic transformation and mechanical/functional properties of Ti-Ta-Hf alloys with various thermo-mechanical treatments were investigated.The results reveal that the hot-rolling could refine the grain size and introduce a certain n
Ring-opening polymerization of N-carboxyanhydrides (NCAs) bearing pendant groups creates functional poly-peptides.In this paper,we report the design,synthesis and polymerization of tetraphenylethylene (TPE)-modified NCA,which is used to incorporate aggreg
The effect of Ge modification on the oxidation of NbSi2 was performed by using the first-principles method based on Density Functional Theory (DFT).The O2 molecule absorption configurations on the ideal NbSi2 (001) surface with and without Ge substitution
The creep behavior and dislocation mechanism of Ni3Al-based single crystal alloys IC6SX with crystal orientation[001]which was prepared by seed crystal method under the testing conditions of 760 ℃/500 MPa,760 ℃/540 MPa and 760 ℃/580 MPa were investigated.
