The Effect of Grain-refinement on Zn-10Al Alloy Damping Properties
The paper is devoted to grain-refinement of the medium-aluminium zinc based alloys (MAl-Zn). The system examined was sand cast Zn- 10 wt. %. Al binary alloy (Zn-10Al) doped with commercial Al-3 wt. % Ti - 0.15 wt. % C grain refiner (Al-3Ti-0.15C GR). Basing on the measured attenuation coefficient of...

Summary: | The paper is devoted to grain-refinement of the medium-aluminium zinc based alloys (MAl-Zn). The system examined was sand cast Zn- 10 wt. %. Al binary alloy (Zn-10Al) doped with commercial Al-3 wt. % Ti - 0.15 wt. % C grain refiner (Al-3Ti-0.15C GR). Basing on the measured attenuation coefficient of ultrasonic wave it was stated that together with significantly increased structure fineness damping decreases only by about 10 - 20%. The following examinations should establish the influence of the mentioned grain-refinement on strength and ductility of MAl-Zn cast alloys. |
