摘要: 基于激光驱动方式建立了一种面向金属粉末的冲击压缩特性研究技术。通过靶型优化设计和实验验证，在实现冲击波加载特性调控的同时，解决了粉末材料无固定几何形状对测量带来的技术困难；在靶结构中采用局部镀膜的方法，解决了粘胶对石英标准材料厚度测量的影响，保证了数据的真实性。利用三维X射线计算机断层成像技术表征实验用靶的装配质量，通过靶物理设计和改进装配方法获得了满足激光驱动金属粉末压缩特性研究的微型靶，实现了不同初始密度的研制。实验数据一致性较好，与独立计算的WEOS模拟结果吻合度高且能有效地区分不同初始密度下的数据趋势。该实验技术可拓展到其他粉末颗粒的冲击压缩特性研究中。Abstract: In order to broaden the pressure range of the research on the physical parameters of powder materials, a high-pressure physical property research technology for metal powders was established based on laser driving method. Through target optimization design and experimental verification, while achieving the regulation of shock wave loading characteristics, the technical difficulties caused by the lack of fixed geometric shapes in powder materials for measurement have been solved; The use of local coating method in the target structure solves the influence of adhesive on the thickness measurement of quartz standard material, ensuring the authenticity of the data. By utilizing three-dimensional X-Ray computed tomography imaging technology to characterize the assembly quality of experimental targets, micro targets that meet the requirements of laser driven metal powder high-pressure physical property diagnosis were obtained through improved assembly methods, and the development of targets with different initial densities was also achieved. While ensuring the accuracy of the data, the pressure range of the powder material is extended to more than 1 TPa. The experimental results show good data consistency, which is consistent with the independently calculated WEOS simulation results and can effectively distinguish the data trends under different initial densities. This experimental technique can be extended to the study of high-pressure physical properties of other powder particles.
