Abstract
Results of a study of a material prepared by impregnating boron carbide with aluminum are reported. A shortcoming of this composite material is that it tends to degrade (at a different rate depending on the conditions) into a powder. Introduction of boron and magnesium diboride enhances the material stability; however, specimens high in aluminum carbide are the most prone to degradation. It is assumed that the process of degradation involves hydrolysis of residual (free) aluminum in the presence of aluminum carbide.
