【 摘 要 】

This paper proposes the lattice density to determine whether the cryogenic treatment can promote the precipitation of the second phase in the magnesium alloy. The lattice density refers to the number of atoms per unit volume in the unit cell. Only when the lattice density of the second phase is smaller than the matrix, cryogenic treatment can play a role in promoting precipitation. The greater the difference in lattice density, the better the cryogenic treatment promotes precipitation.
