| 摘 要： | 氢化锂（LiH）是重要的热核材料，其状态方程参数是惯性约束聚变研究的重要内容。本工作采用真空热压技术制备氢化锂薄膜，在真空度小于5.0×10-4 Pa，温度450 ℃，升温速率10 ℃/min，采取分段加压、退火，获得了厚度小于100 μm、厚度一致性约98%的氢化锂薄膜，表面粗糙度小于100 nm，热压后密度增加，达到0.780 g/cm3。X射线衍射分析结果表明：薄膜的主要成分为氢化锂，薄膜存在择优取向、内应力、晶粒细化等特征。

| Abstract: | Welding with impacting rotation compression was applied to control the TC4 thin plate buckling for the weld uneven heating. Influences of the welding on the weldment microstructure and joint properties were studied. Metallographic observation, Vickers hardness measurement and tensile tests of the joints were carried out. The result shows that based on the controlling of the buckling phenomena of TC4 thin plate weldment, the welding with impacting rotation compression decreases the hardness of the compressed part, the strain hardening does not occur, and the microstructures before and after impacting rotation compression are similar. |
