| description | In the present work, the effect of growth rate and temperature gradient on
microstructure and mechanical properties of Zn-7wt.%Al-4wt.%Cu eutectic alloy
has been investigated. Alloys prepared under steady-state conditions by
vacuumed hot filing furnace. Then, the alloys were directionally solidified
upward with different growth rates (V=11.62-230.77 mm/s) at a constant
temperature gradient (G=7.17 K/mm) and with different temperature gradients
(G=7.17-11.04 K/mm) at a constant growth rate (V=11.62 mm/s) by a Bridgman
furnace. The microstructures were observed to be lamellae of Zn, Al and
broken lamellae CuZn4 phases from quenched samples. The values of eutectic
spacing, microhardness and ultimate tensile strength of alloys were measured.
The dependency of the microstructure and mechanical properties on growth rate
and temperature gradient were investigated using regression analysis. |
