Effect of reverse modification of Al–5Ti–B master alloy on hypoeutectic ZnAl4Y alloy
Highlights ► Reverse modification of Al–5Ti–B master alloy on ZnAl4Y alloy was investigated. ► After modification, the morphology of primary phase of ZnAl4Y alloy vary greatly. ► Mechanical properties of the modified ZnAl4Y alloy are enhanced considerably. ► Some explanations for the formation of primary α-Al phase in ZnAl4Y alloy.
Abstract The present work focuses on reverse modification of Al–5wt.%Ti–1wt.%B master alloy on the structural characteristics and mechanical properties of hypoeutectic ZnAl4Y alloy. The results shows that with the increase of the adding amount of master alloy to ZnAl4Y alloy, the morphology and the kind of primary phase as well as the amount of eutectic structure of the modified alloy vary considerably. With the increase of the adding amount of Al–5wt.%Ti–1wt.%B, the tensile strength and the hardness of modified ZnAl4Y alloy increase. When the adding amount is 0.5wt.%, the impact toughness and the elongation of the alloy reach the maximum.
