在本工作中，对预变形的 Mg-10Gd-3Y-0.3Zr 固溶体合金进行退火，随后进行压缩，并分析了溶质与孪晶界之间的相互作用。研究发现，退火过程中溶质原子向形变孪晶界的偏析导致Mg-10Gd-3Y-0.3Zr合金的强度增加，且Gd溶质原子比Y具有更大的强化作用，强化效果随着孪晶密度、退火时间和退火温度的增加而增加。然而，低温退火时间过长会因回复而导致强度略有下降。证实高温下变形孪晶边界处溶质原子的有序偏析变得不稳定，导致强度迅速下降。
In the present work, pre-deformed Mg–10Gd–3Y–0.3Zr solid solution alloy was annealed, followed by subsequent compression, and the interaction between solutes and twin boundaries was analyzed. It is found that the segregation of solute atoms to deformation twin boundaries during annealing leads to the increase in strength of Mg–10Gd–3Y–0.3Zr alloy, and Gd solute atom has a larger strengthening effect than that of Y. The strengthening effect increases with increase of twin density, annealing time and annealing temperature. However, too long annealing time at low temperature decreases the strength slightly due to the recovery. It is verified that the ordered segregation of solute atoms at the deformation twin boundary becomes unstable at high temperatures, which gives rise to the rapid decrease in the strength.
