摘要：

Kinetics of decomposition of the supersaturated solid solution in the Mg-3.3 wt % Yb alloy has been investigated during aging in a temperature range of 150-225 degrees C using electron microscopy, X-ray diffraction, and hardness measurements. Mechanisms of the decomposition of the supersaturated solid solution and the nature of phases precipitating at different stages of aging, namely, in the underaged, maximum-hardness, and overaged states, have been established. The character of structural components responsible for the hardness changes during aging process has been established.
