Abstract
Cu-Ti alloys were strengthened by Cu4Ti intermetallic compound precipitation in a Cu matrix during aging. The Cu-3.5 wt% Ti(Cu-4.6 at% Ti) alloys without deformation and with uniform and non-uniform deformation were aged at 450 oC for various times after solution treatment at 885 oC. The uniformly and non-uniformly deformed alloys..... More

Abstract
In this study, we established a correlation between the electrical conductivity and catalytic properties of vanadium borophosphate glass containing Fe2O3. Glasses were synthesized in the 78V2O5–15P2O5–7B2O3 ternary-system containing x mol% Fe2O3 (x = 1, 5, 7.5, and 10). Electrical conductivity was measured at 45 ℃ for samples heat-treated at 340.....
