We report on the mechanical properties of xCuO-(50-x)PbO-50B2O3 (x from 0 to 30mol%) copper-lead-borate glasses. Their mechanical properties were investigated by the mechanical resonance technique and by the indentation measurement. The replacement of lead by copper improves the packing efficiency, and enhances the elastic moduli, hardness and the fracture toughness of glasses. © 2016 Trans Tech Publications, Switzerland.
