Abstract
Mg-alloys are highly applicative at the automobile and aerospace industries due to their high specific mechanical properties. Mg-Al-RE alloy design was motivated by the formation of Al-RE intermetallic at the grain boundaries (GB) and Mg2Sn precipitates inside the α-Mg matrix. The presence of precipitates at the GB can inhibit GB sliding, while the precipitation inside the α-Mg matrix grains inhibits dislocation climb responsible for a bulk creep. Thermodynamic simulations were used for optimal composition and process parameters derivation. Mg-Al-Zn-Sn alloys with additions of Nd and Ce were examined in terms of creep resistance and microstructure development during aging and creep. The evolution of the microstructure was monitored by scanning electron microscopy and X-ray diffraction. Mechanical properties were examined by creep testing and Vickers microhardness measurements. A directional growth of the MgZn2 precipitates was found in the crept specimens in contrast to the aged counterparts.
