Abstract

explains the efffects of Ce content on the properties as well as on the formed morphologies and scales.Al-Ce alloys are anticipated to offer high-temperature strength. In recent years, interest in these alloys has increased. While previous studies have looked into dendritic length-scale and how it relates to tensile properties, cellular growth has not been debated, despite its well-known significance. An in-depth study of Al-4, 6 and 10.1 wt.% Ce alloys involving microstructural analysis of Cu-mold centrifugal cast samples at various points, Vickers hardness, SEM and tensile properties was carried out here. α-Al cells were identified for a computed solidification velocity of 3.1 mm / s and a cooling rate of 155 K / s. These samples showed balanced tensile properties.
