| 摘 要： | 采用电弧熔化快速锤砧急冷技术制备含Tb直到10at.-%的Ag-Tb合金箔,厚度0.05—0.08mm,其冷却速度为10~6K/s数量级,采用晶格参数法确定Tb在快速凝固Ag-Tb合金中亚稳扩展固溶度可达到5at-%,确定亚稳共晶中的第二相为Ag_3Tb,观察了快凝Ag-Tb合金的显微结构与缺陷。

| Abstract: | The 0.05--0.08mm thick splat foils of Ag-Tb alloy, containing Tb up to 10 at.-%,were made by the hammer-anvil technique. The cooling rate was in order of 10~6K/s. The me-tastable extension of solid solubility of Tb in the rapidly solidified Ag-Tb alloy was measuredto be up to 5 at.-% by lattice paramter method. The secondary phase in metastable eutecticstructure was identified as Ag_3Tb from diffraction pattern. The microstructure and micro-defect in as-quenched Ag-Tb splat foil were also observed. |
