The dendritic primary phase in the conventionally cast A380 alloy has readily transformed into a non-dendritic one in ingots cast over a cooling plate from pouring temperatures between 615, 630 and 650 °C. After the casting process, isothermal treatment was carried out at 565 °C in induction unit. Isothermal treatment yields a globular microstructure. To determine the tribological properties of this alloy, a pin-on-disc tribometer was used to carry out tribological tests under dry sliding conditions. The results showed that both cooling slope casting and isothermal treatment has an effect on tribological properties. © (2011) Trans Tech Publications, Switzerland.EnglishAluminum alloysCerium alloysCoolingMetal castingsMicrostructureTribologyCasting processConventionally castsCooling platesCooling slope castingCooling slopesDry slidingGlobular microstructureGlobular microstructuresInduction unitsIsothermal treatmentKey featurePin on disc tribometerPouring temperaturesPrimary phaseSemi-solid formingTribological propertiesTribological testsWear behaviorsCastingConference paper10.4028/www.scientific.net/AMR.264-265.42
