Opis:: In the paper, the changes in some mechanical properties and wear behavior of CuSn10 sintered bronze and MMCs based on this bronze reinforced with composite ultrafine aluminide powders FeAl/15 % Al2O3, NiAl/15 % Al2O3 and Ti-46Al-8Cr are described. It was observed that the presence of aluminides in the MMCs leads to an increase in the hardness, but the flexural strength may increase or decrease depending on the type of aluminide. The presence of aluminides in the MMC reduces the wear rate considerably. It is decreased in the direction of FeAl/15 % Al2O3 → NiAl/15 % Al2O3 → Ti-46Al-8Cr aluminides and for the best MMC composition the advantage is about 20 times. In the MMCs wear process, micro-craters are formed on the contact surface and it is the principal reason of a decrease in the wear rate.

Opis:: Peculiarities of phase composition and morphology in nanostructured (Fe$\text{}_{70}$Al$\text{}_{30}$)$\text{}_{1-x}$(Al$\text{}_{2}$O$\text{}_{3}$)$\text{}_{x}$ (x=64-80 wt.%) powder alloys prepared by self-propagated high temperature synthesis have been studied by $\text{}^{57}$Fe transmission Mössbauer spectroscopy, scanning electron microscopy, and X-ray diffraction. It has been established that phase composition of alloys has not been affected by Al$\text{}_{2}$O$\text{}_{3}$ contribution. Contrary, atomic arrangement in B2 FeAl phase depends on the volume fraction of Al$\text{}_{2}$O$\text{}_{3}$ resulting in the migration of Al atoms from B2 FeAl lattice.
