dc.description.abstract The AlSi10Mg alloy is known for its castability, corrosion resistance, high heat conductivity, low weight and good weldability. The applications of the aluminium alloy components includes heat exchangers that are subjected to high temperatures and corrosive environments. The production process of AlSi10Mg alloy using selective laser melting (SLM) has been extensively explored because of its hypoeutectic composition of Al and Si. However, it has been observed that stress relieve has a negative effect on tensile properties of SLM built samples, while retaining and improving ductility. Therefore, this study aims to investigate the thermal behaviour of AlSi10Mg alloy produced by SLM process with the specimen heat treated at 300°C for 2 hours. The specimens exhibited mass gain during the TGA (Thermalgravimetric Analysis) as a result of the precence of oxygen as one of the elements present as detected by the EDS analysis. The fatigue results post thermal treatment demonstrated improved fatigue resistance qualities comparable to casted AlSi10Mg. en_US
