摘要

A comprehensive transmission electron microscopy investigation was conducted to gain insights into how the secondary phases in Mg-1.50Zn-0.25Gd alloys are transformed during hot compression. It was found that needle-like Mg₄Zn₇ phases precipitate in Mg matrix, yet vanish during compression, forming nano-quasicrystals. These nano-quasicrystals are found to nucleate on the Mg₄Zn₇ phase with orientation relationships [₁₁₂â€-[Mg₄Zn₇[2-fold] _I-phase, indicating that the crystal phase can transform to the quasicrystalline phase. The formation mechanism of the quasicrystals in Mg alloys at the nanoscale is also discussed.
