介绍了使用差示扫描量热法、透射电子显微镜 (TEM)、X 射线衍射、场离子显微镜、原子探针断层扫描 (APT) 和小角中子散射 (SANS) 对非晶 Cu47Ti34Zr11Ni8 结晶的研究结果。这些实验技术用于表征在玻璃化转变温度附近的不同温度下热处理的所制备的样品和样本。 APT 和 SANS 显示合金在晶相成核和生长之前分解成富铜和富钛区域。 TEM 显示主成核相具有面心立方结构。
The results of a study on the crystallization of amorphous Cu47Ti34Zr11Ni8 with the use of differential scanning calorimetry, transmission electron microscopy (TEM), x-ray diffraction, field ion microscopy, atom probe tomography (APT), and small-angle neutron scattering (SANS) are presented. These experimental techniques were used to characterize as-prepared samples and specimens heat treated at different temperatures around the glass transition temperature. APT and SANS show that the alloy decomposes into copper-enriched and titanium-enriched regions prior to nucleation and growth of a crystalline phase. TEM shows that the primary nucleating phase has a face centered cubic structure.
