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%
