Influence of Temperature Rise in Penetration of W_f/Zr-Based Amorphous Matrix Composite Projectile on Target Material

Abstract:

W_f/Zr-based amorphous matrix composite is supposed as a potential penetrator material of armor-piercing projectile because it has both advanced piercing performance and environmentally friendly property, and it becomes the hot spot of science study and engineering application. To get a deeper understand of the penetration mechanism and the influence of temperature rise on structure of target, target which is penetrated by penetrator made of W_f/Zr-based amorphous matrix composite is studied by SEM and micro-hardness tester. Oxidation of back of target is severe, and Martensite transformation happens around the crater. From the crater surface to the interior of the steel target, the section can be divided into 3 layers: the Martensite layer, the deformed fine grain layer and the normal matrix. Martensite transformation indicates the target steel around crater is heated and softened in penetration, so this phenomenon is beneficial to penetrate and get a deeper understand of the penetration mechanism.
