摘要: Abstract Structural modification of high-zinc aluminium alloys influences their strength and damping properties. In a series studies, Al – 20 wt. % Zn alloy (Al-20Zn) has been doped with Ti introduced ZnTi-based master alloy. The structure mechanical properties have studied using: SEM (scanning electron microscopy), LM (light measurements. Grain refinement leads to significant improvement in ductility the Al-20Zn while preserving good tensile strength. attenuation coefficient for 1 MHz ultrasound decreases by about 24%; refined are, however, still clearly classified as high-damping.
