for compressible strength and fracture behavior at 300-1 373 K. The results show that the elevated temperature 0.2% compressible yield strength as well as the room-temperature compressible fracture...

that, with annealing temperature increasing, the volume fraction of primary α(αp)-phase decreases while that of transformed β(βt)-structure and secondary α(αs)-phase increases. The room-temperature strength...="ChDivSummary" name="ChDivSummary">Ti-62421 S(Ti-6 Al-2 Sn-4 Zr-2 Nb-1 Mo-0.2 Si)is a novel short-time using high-temperature titanium alloy.The effects of annealing on microstructure and tensile......
luminescent lifetimes.Here,a room-temperature co-precipitation method was used to synthesize europium(III) activated La1-xGdxF3 solid phosphors.X-ray diffraction(XRD) data confirmed the crystalline phases......
. The preferred growth direction of the nanowires is [001]. Many nanowires are found to have a dendritic structure and temperature grade is thought to be the main cause of the growth of this structure. Zn nanoparticles scattered on the surface of the MgO rods are thought to be the catalyst of the VLS (vapor-liquid-solid) growth of the MgO nanowires. Room-temperature photoluminescence measurements show......
