Phase composition and morphology development in WE-type alloys modified by high Zn content
Original language description
Quasicrystalline icosahedral equilibrium phase was found in Mg-Y-Nd (WE43) alloys with the addition of 12 wt.% and 25 wt.% Zn constituting grain boundary eutectic phases. In response to the isochronal annealing morphologically similar precipitates of thephases with the same structure as those developing during heat treatment of binary Mg-8wt.%Zn alloy at temperatures higher than 150°C were observed, namely ?1' (b-centered monoclinic crystal structure a=2.596 nm, b=1.428 nm, c=0.524 nm, ?=102.5°) and ?2' (hexagonal MgZn2). Development of the resistivity and microhardness during isochronal annealing corresponds to the phase transformations and morphology changes of the phases observed. Dislocations with the c Burgers vector component generated due to the presence of icosahedral phase are responsible for the improved formability as compared to the WE43 alloy.
