Structural Studies and Convergence Scenario for a Shell Made of Mg–Zn–Zr Magnesium Alloy

The paper considers the deformation behavior of a cylindrical shell made of industrial wrought magnesium alloy MA-14 (Mg 93 wt %–Zn 5–6 wt %–Zr 0.3–0.9 wt %) loaded by a method of sliding detonation of a laid-on explosive uniformly placed on the outer surface of the shell. The convergence scenario of the magnesium alloy shell is analyzed on the basis of the X-ray data. The methods of optical and scanning electron microscopy are used to investigate the evolution of the structure at high-rate deformation. The hardness is measured along a radius and over the length of the shell.
