Single-phase aluminum diboride was obtained by thermal explosion of an aluminum–boron mixture mechanically activated in a planetary ball mill. The additional mechanical treatment of the products of thermal explosion was found to reduce the coherent scattering area size of AlB

to nanometer values. The results of x-ray phase and electron microscopy of the mechanocomposites and products of thermal explosion are presented.
