Abstract
An explosively formed penetrator (EFP) is a kind of kinetic energy warhead that contains a metal linear structure. After exploding, the linear structure in the EFP is deformed and hits the target as a form of aero-stable long-rod penetrator. To achieve high penetration performance, Ta is commonly used as the.....

DOI: https://doi.org/10.3365/KJMM.2018.56.5.360

Abstract
This study attempted to utilizing the kinetic spray process to manufacture tantalum coating layer and investigated the effect of carrier gas on the microstructure and macroscopic properties of the coating layer. The initial powder feed stock was a massive powder with an average particle size of 24.35 μm and 99.99%..... More
