| 中文摘要: |
| 通过熔炼、热轧、冷轧及均匀化退火处理制备得到Ni-10Pt合金靶材和Ni-18Cr-10Pt合金靶材。采用金相、X射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)等手段研究Cr的添加对NiPt合金结构、力学性能以及物理性能的影响。研究表明，向NiPt合金中加入Cr后，平均晶粒尺寸从67.26 μm下降到10.24 μm，发生明显的晶粒细化；屈服强度从201.31 MPa大幅度提高到520.11 MPa，均匀延伸率仅从39.22 %下降到了31.94 %。同时，Cr的添加还降低了合金在室温下的热膨胀系数，并且使合金的铁磁性消失。 |
| 英文摘要: |
| NiPt and NiCrPt alloy target were prepared via a process of melting, hot and cold rolling, and annealing treatment. The effect of Cr addition on the structure, physics ad mechanical properties of NiPt alloy was studied by using optical microscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission electron microscopy (TEM), etc. It was found that the average grain size of NiPt alloy decreased from 67.26 μm to 10.24 μm after the addition of Cr, indicating a significant grain refinement, and the yield strength increased significantly from 201.31 MPa to 520.11 MPa, while the uniform elongation shrunk only from 39.22 % to 31.94 %. Moreover, the addition of Cr also reduced the thermal expansion coefficient of the alloy, resulting in the disappearance of ferromagnetism. |
