چکیده
|
Microstructure and properties of the al-6si-0.3mg alloys containing scandium (0.2 to 0.6wt %) 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.
