Summary

Excellent high performance magnesium alloys based on alloying with thorium (e.g. HK31 and HZ 32), applicable up to 350 °C, are being phased out due to their weak radioactivity. The best substitution, namely commercial alloys WE54 and WE43, owe their good mechanical properties to the morphology and thermal stability of precipitates formed by T6 treatment [1, 2].
