Structural Stability of Mg–6Al–2Sr Magnesium Alloy

Abstract:

The Mg–6Al–2Sr magnesium alloy containing 6.15 at.% of aluminium, 2.1 at.% of strontium and 0.42 at.% of manganese was investigated at sand casting state performed at 700°C and after annealing treatment at 180°C, 250°C and 350°C during 500÷5000h with cooling in air. In the as-cast conditions the Mg–6Al–2Sr alloy consisted of α-Mg grains with intermetallic phases: (Al,Mg)4Sr, Al8Mn5 and Al3Mg13Sr. Annealing at 180°C resulted in the precipitation of the Mg17Al12 phase in the aluminium enriched area and the beginning of decomposition of the Al3Mg13Sr phase. Annealing at 250°C causes further decomposition of the Al3Mg13Sr phase while no precipitates of the Mg17Al12 phase could be observed. After exposure at 350°C the total decomposition of the Al3Mg13Sr phase into a mixture of the Al4Sr and α-Mg phases has been observed
