Dynamic compressive mechanical responses of selective laser-melted Ti-6Al-4V alloy were studied in terms of the influences of scanning speed, building angle as well as impacting strain rate. It was found that the ultimate flow stress and energy absorption increased first and then dropped sharply as the scanning speed increased from 1.0 to 1.6 m/s, showing that the sample built at scanning speed of...
A novel phosphor, Mn4+ doped La2LiTaO6, was developed by solid-state reaction method. The luminescent spectra and emission efficiencies of La2LiTaO6:Mn x4+ (x = 0.001, 0.003, 0.005 and 0.01) were discussed. The effects of co-doped charge compensation ions, M = Mg2+, Ca2+, Na+, were investigated, respectively. The excitation spectra indicated that La2LiTaO6:Mn4+ could be effectively excited by...
