Fabrication of W-Mo-Ti system flier-plate with graded impedance for generating quasi-isentropic compression

A fully dense W-Mo-Ti system flier-plate with graded impedance in its thickness direction was successfully fabricated by the method of powder metallurgy. The result of the impact experiment on a light gas gun showed that dynamic quasi-isentropic compression has been created.     

W-Mo-Ti 体系波阻抗梯度飞片的制备与准等熵压缩特性

采用粉末冶金方法,制备出整体致密、波阻抗沿厚度方向呈特定分布的Ｗ－Ｍｏ－Ｔｉ体系梯度飞片。在一级轻气炮上进行的击靶实验结果表明,利用该梯度飞片可以实现对靶材料的准等熵压缩。
