Modification of sintered iron properties by Y₂O₃ nanoparticles

Autor: Cherednyk, M.I., Popov, O.Yu., Chornobuk, S.V., Totsky, I.M., Semenko, M.P., Boshko, O.I., Tkachuk, V.Ja., Slobodianyk, Y.V., Naumenko, S.M., Makara, V.A.

Influence of Y₂O₃ nanoparticles on sintered iron structure and microhardness is investigated. Ferrite grain growth is shown to be slowed down by the clusters which cause altering the grain shape from needle-like to equiaxial (with lower specific

Effect of magnetic field on microhardness of germanium

Autor: Makara, V.A., Steblenko, L.P., Kuryliuk, A.M., Naumenko, S.M., Kolchenko, Iu.L., Kravchenko, V.M.

Microhardness variations in germanium crystals caused by a weak constant magnetic field have been studied. It is fount that the magnetomechanical effect, that is relative change in microhardness, becomes relaxed in time. The results obtained indicate

Silicon crystal strength reduction due to magnetoresonance

Autor: Makara, V.A., Pogorilyi, A.M., Steblenko, L.P., Kuryliuk, A.M., Naumenko, S.M., Kobzar, Yu.L., Kravets, A.F., Podyalovsky, D.I., Matveeva, O.V.

The magnetoresonance influence as well as the micrawave superhigh-frequency (SHF) magnetic field effect on the microhardness of silicon crystals has been studied. It is established that the action of SHF field results in decreasing microhardness, whi

Effect of weak magnetic field on structural arrangement of extrinsic oxygen atoms and mechanical properties of silicon monocrystals

Autor: Makara, V.A., Steblenko, L.P., Kolchenko, Yu.L., Naumenko, S.M., Lisovsky, I.P., Mazunov, D.O., Mokliak, Yu.Yu.

IR spectroscopy study is indicative of the change in the relative concentration of interstitial oxygen in silicon monocrystals after their treatment by using the magnetic field. This is an evidence of a considerable effect of magnetic field on the de

Relation between structure inhomogeneities and relaxation processes in excited silicon crystals

Autor: Makara, V.A., Kolomiets, A.M., Kolchenko, Yu.L., Naumenko, S.M., Rudenko, O.V., Steblenko, L.P.

The part played by electric current pulses in formation of residual electroplastic effect and the "electric memory" effect in dislocation-containing silicon crystals has been investigated. The character of the observed effects has been found to be de
