Abstract

This study elucidates how scandium addition and T7 heat treatment affects thermal stability and corrosion properties of A201 alloy. The as-cast and the T7 heat-treated specimens were thermally exposed at 300 °C for 120 h to investigate the evolution of the Sc-free and the Sc-containing alloys. The results indicated that adding 0.6 wt.% scandium to A201 alloy could produce Al3Sc, W phase (Al8-5.4Cu6.6-4Sc) and grain refinement, significantly enhancing the hardness and tensile strength in as-cast condition. The as-cast A201 alloy containing Sc also showed the least loss of hardness and strength during thermal exposure at 300 °C. In addition, the presence of W phase weakened the peak hardness and tensile strength of the Sc-containing A201 alloy during T7 heat treatment. Adding Sc to A201 alloy increased corrosion resistance in T7 heat-treated condition, but slightly decreased corrosion resistance in as-cast condition.
