説明
The yield stress of Al-Mg polycrystalline alloys follows the Hall-Petch relation: σy=σO+Kyd-1/2, where both the friction stress, σO and pinning constant, Ky depend on the quenching temperature and Mg content, C. The relation between σO and C can be experimentally expressed as σO=0.6με4/3C, where μ is the shear modulus and ε is the size misfit parameter. This result agrees well with a theory of solid solution hardening. The friction stress σO increases as the quenching temperature increases, which can be attributed to the increase in the number of quenched-in vacancies. The fact that the pinning constant Ky decreases as the quenching temperature increases and as the Mg content decreases, can qualitatively be explained by the size of Cottrell atmosphere.
