Abstract:
Microstructure and properties of the Al-۶Si-۰.۳Mg alloys containing scandium (۰.۲ to ۰.۶wt %) were investigated. The microstructure was observed by optical microscopy, the hardness was determined by Vickers tester and phase transformation was investigated by differential scanning calorimetry (DSC) technique. The results showed that scandium can refine dendrites, enhance hardness in the aged alloys and suppress softening effect during prolonged ageing treatment.
