| Abstract |
The tensile strength and yield strength were measured in unidirectionally solidified Al-Cu binary alloys along with the secondary dendrite arm spacing to see the relationship between them. Small amounts of Mg and Zn are added to these binary alloys to study the effects on the dendrite spacings and therefore on the mechanical properties. The addition of Zn and Mg decreases the dendrite arm spacings and increases the mechanical properties of alloys. The decrease of dendrite spacing was explained in terms of Cu solute atom diffusivity effected by the addition elements. |
