状态方程靶用钼薄膜精密轧制工艺研究

Precision Rolling Technique of Molybdenum Foil for Equation of State

  • 摘要: 材料的高压状态方程实验是惯性约束聚变研究的重要内容,冲击绝热线测量是确定材料高压状态方程和其它动高压性质的基础。本工作主要研究了钼薄膜标准材料的精密轧制工艺,制定了合理的轧制工作曲线,并进行了验证。对轧制出的钼薄膜样品进行了必要的分析测试和表征,结果表明:轧制出的钼薄膜的厚度一致性可达到99%,表面粗糙度Rq小于50 nm,峰谷极差小于200 nm,能够满足目前状态方程实验的需求。

     

    Abstract: The high pressure equations of state (EOS) of materials are important issues in research of inertial confinement fusion (ICF). The shock hugoniot curve of materials is the foundation to determine high pressure equations of state and other high dynamic pressure properties of materials. Precision rolling techniques of molybdenum film standard materials were described with reasonable working curve made and verified. Measured data of the rolled molybdenum film show that the film has high thickness uniformity better than 99% with surface squared mean roughness less than 50 nm and peak-to-vale less than 200 nm which can fulfill the request of EOS experiment up to date.
