摘要
Ａｌ－Ｌｉ单晶体（７７Ｋ和２９３Ｋ）的塑村流变行为表明，Ａｌ－Ｌｉ单晶体的极限拉伸强度σｂ和最大均匀应变εｂ在低温下有所提高；形变硬化率ｄσ／ｄε和形变硬化指数ｎ的增加表明其均匀变形能力得以提高；
The research of Al-Li binary single crystals at cryogenic (77K) and room temperature (293K)shows the improvement of oh and εb at 77K. The increasing of work hardening rate (dσ / dε) and its exponent (n) enhance the ability of homogenization of deformation. The PLC effect in Al-Li single crystals is a combination consequence of the shearing of the coherent δ' particles and the diffusion of solute Li atoms.
