文摘

Effects of different RE addition on a hypoeutectic as cast AlSi alloy are studied. EDX, XRD, and DTA analyses of AlSi-RE samples are carried out. Decrease in eutectic temperature is similar for all AlSi-RE samples. Decrease in Vickers hardness is similar for all AlSi-RE samples. RE addition increases corrosion resistance in 3.5 wt% NaCl solution.
