Abstract

The microstructure and mechanical properties of Al₈₆Ni ₆Y_6-xCo₂Pd_x (x = 0, 0.5 and 1) rods, with a 1 mm diameter, have been investigated. The Al₈₆Ni ₆Y₆Co₂ alloy consists of ductile fcc-Al and hard Al₃Ni intermetallic phases embedded in the matrix. Replacing Y by Pd in the Al₈₆Ni₆Y₆Co₂ alloy promotes precipitation of additional crystalline phases, producing composite materials with tuneable mechanical behaviour. Compared to conventional Al-based crystalline alloys, the Al₈₆Ni₆Y₆Co₂ rod is relatively hard (395 HV) but exhibits a brittle behaviour when compressed at room temperature. The compressive plasticity increases to 1.5% in the Al₈₆Ni₆Y_5.5Co₂Pd_0.5 alloy but the hardness decreases in this case. The plasticity, hardness and elastic properties of these alloys depend on the amount and intrinsic properties of the different constituent phases, as well as on the resulting microstructure obtained after the casting process (i.e., the size and shape of the precipitates).
