    摘要:

    研究了30W-Cu EFP藥型罩的制備及成形性能。采用普通鎢粉、銅粉和超細(xì)鎢銅復(fù)合粉制備兩種不同的棒材，然后測試棒材的鍛造性能，最后選用鍛造性能好的材料制備EFP藥型罩。研究表明：采用普通鎢粉、銅粉制備的材料具有較好的壓力加工性能；所制備的30W-Cu EFP藥型罩材料的致密度達(dá)98.2%理論密度，退火后材料的抗拉強(qiáng)度達(dá)到315 MPa，延伸率達(dá)15.3%

    Abstract:

    The preparation and formability of 30W-Cu EFP(explosively formed projectile) liner were studied. At first the two different 30W-Cu materials were prepared by tungsten powder, copper powder and ultrafine tungsten-copper composite powder, and then the two materials’ formability were tested. Finally the material which had good formability was used to prepare EFP liner. It was found that the 30W-Cu material prepared by common tungsten powder and copper powder had a good formability. 98.2% of the theoretical density of the density of the 30W-Cu EFP liner material was obtained. After annealing, the tensile strength of the material reached 315 MPa and elongation reached 15.3%
