Abstract: A W-Mo-Ti system flier-plate material with graded wave impedance, which can realise quasi-isentropic compression and has important application in dynamic high-pressure technology, was prepared. The impedance distribution of the flier-plate was designed via numerical simulation. Then, W-Mo and Mo-Ti composites with gradually-changed compositions were stacked and sintered at 1473K-30MPa-10min to prepare the W-Mo-Ti system flier-plate material. The wave impedance of the flier-plate changed quasi-continuously along the thickness direction in a parabolic distribution form. By using the W-Mo-Ti flier-plate, a quasi-isentropic compression wave with a slowly-rising front was obtained.
