EFFECT OF OXIDE LAYER THICKNESS OVER Al AND Al ALLOY POWDERS ON QUALITY OF THEIR EXPLOSIVE COMPACTS

摘要

Observations of microstructure of explosive compacts made of Al or Al-Li alloy powdersby atomization with water,nitrogen or ultrasoic Ar gas were carried out under optical andscanning electron microscopes.The rsults indicate that super quality explosive compactcan only be obtained by powders of which the thickness of the oxide layer is less than30 nm.
