Microstructure and thermal stability of MgZnYAl alloy containing cluster-arranged nanoplates (CANaPs)

Popis výsledku v původním jazyce

The thermal stability of the microstructure of Mg - 0.9 % Zn - 2.05 % Y - 0.15 % Al (at.%) alloy prepared by conventional extrusion (CE) from cast ingot and rapidly solidified (RS) ribbon consolidation method has been investigated by scanning and transmission electron microscopy. It is shown that in the initial state, although both microstructures consist of small recrystallized and large non-recrystallized grains, the distribution and morphology of the solute-enriched phases are strongly influenced by the processing route. Particularly, the RS alloy mainly contains fine homogeneously distributed cluster-arranged nanoplates (CANaPs), while the CE alloy is characterized by larger solute-enriched phases (incl. CANaPs and LPSO fractions) together with individual cluster-arranged layers (CALs) and/or thin CANaPs. Differences in the size and distribution of solute-enriched phases naturally affect the recrystallization dynamics during post-processing heat treatment. Nevertheless, both types of material exhibited exceptionally high thermal stability up to 300 degrees C, which significantly exceeds the values reported for conventional Mg alloy systems.
