The structure of a metal matrix composite based on aluminum containing 6, 17 and 24 wt % Al2 O3 was studied by atomic force microscopy. The composite was prepared by the method of magneticpulse compaction from aluminum nanopowder obtained by the electric wire explosion method. The samples compacted at 400 ◦ C have more clearly expressed grain boundaries than those obtained at room temperature. The structure of a composite subjected to dynamic plastic deformation is studied.

The paper considers the influence of a transition amorphous layer at the interface between the higher manganese silicide (HMS) Mn 4 Si 7 and silicon doped with manganese (Si ) on the photoelectric properties of heterostructures. The role of the initial structural defects in the near-surface layers of the single-crystal silicon on the penetration of manganese atoms into Si upon doping from the gas phase is shown.It has been established that at high temperatures (T>1050 ◦ C) Mn atoms deposited on the silicon surface group together (due to surface diffusion), forming droplets of liquid manganese, which dissolve the near-surface …
