Room temperature static recrystallization phenomenon in a deformed Mg96.6Zn1Y2.2Zr0.2 alloy
Source abstract
Abstract
Room temperature static recrystallization phenomenon was observed in a deformed magnesium alloy (solid solution Mg 96.6Zn 1Y 2.2Zr 0.2 (at.%)), which was compressed at room temperature to a strain of 31.6% and placed naturally for 62 months. By characterizing the microstructure before and after natural placement with transmission electron microscopy, it was determined that the recrystallization mechanism was associated with the activation of a significant number of {10 1 ¯ 2} twins and 〈 a〉 or 〈 c + a 〉 dislocations during the compression process, as well as the hindrance to dislocations of twin boundaries and stacking faults that were enriched with solute elements. These findings not only demonstrate that static recrystallization can occur at low strains and low temperatures over extended periods for some alloys, but also emphasize the importance of monitoring the microstructure and properties of the cold-worked alloys during long-term service without heat treatment.
