Abstract
Single-phase aluminum diboride was obtained by thermal explosion of an aluminum-boron mixture mechanically activated in a planetary ball mill. It was established that the additional mechanical treatment of the products of thermal explosion made it possible to reduce the coherent scattering area size of AlB2 to nanometer values. The results of X-ray phase and electron microscopy of the mechanocomposites and products of thermal explosion are presented.
