Co-Ga合金β相的点阵常数随at.％Ga成份而变化,在48at.％Ga处有一最大值。在富Co端能被解释为替代式固溶体,但在富Ga端存在什么类型固溶体?本文用正电子湮没寿命和S参数来研究Co-Ga体系中β相固溶体的类型。
The lattice constant of the Co-Ga alloy β phase varies with the composition of at.% Ga, with a maximum at 48 at.% Ga. What can be interpreted as an alternative solid solution at the Co-rich end, but what type of solid solution is present at the Ga-rich end? The positron annihilation lifetime and the S-parameter are used to study the type of β-phase solid solution in the Co-Ga system.
