Effect of spherical converging stress waves on aluminium and quartz powdermixture

Elemental powders of aluminium and quartz were undergone the loading by sph erical converging stress waves. The layer-by-layer analysis of the structur e and phase composition of the recovered compact was performed using X-ray diffraction, optical and scanning electron microscopy. The occurrence of se veral concentric zones containing the products of different chemical reacti ons along with the initial components was revealed. Pure Si, Al2O3 compound , and Al-Si alloy are the basic products of the chemical reactions.
