Tensile and fatigue properties of a cast aluminum alloy with Ti, Zr and V additions

► A new Al-7Si-1Cu-0.5Mg alloy with further additions of Ti, Zr and V is developed. ► Considerably higher yield strength and ultimate tensile strength are achieved. ► The developed alloys exhibit cyclic stabilization at low strain amplitudes. ► With increasing strain amplitude the extent of cyclic hardening increases. ► Stronger hardening ability under cyclic loading than monotonic loading is observed.
