Theoretical analysis for self-sharpening penetration of tungsten high-entropy alloy into steel target with elevated impact velocities

The “self-sharpening” effect has been observed experimentally in the penetration of tungsten high-entropy alloy (WHEA) into steel targets in previous study. From the microscopic observation of the residual WHEA long-rod projectile (LRP), the multiphase structure at micro-scale of WHEA is the key effects on self-sharpening penetration process. In order to describe the distinctive penetration behavior, the interaction between micro phases is...
