C).Obtained following results:1. The features of internal friction caused by over-expression of structural plasticity in fine-Be, and verified the proposed phenomenological model of internal friction for this case.2. The study and relaxation properties zernohranychnoyi SEG-rehatsiyi scandium, yttrium and copper found that the desired degree of crushing grains of copper can achieve its microalloying significantly cheaper than scandium, yttrium.3. austenitic steel H18N10T strengthened by the addition of oxide ZrO2, in the 445-?S you revealed a new peak of internal friction about the origin of impurity caused by uncontrolled impurity segregation of phosphorus in the grain boundaries. Additives steel H18N10T bind phosphorus oxide ZrO2 as "phosphorus" peak of internal friction zme-nshuyetsya with increasing concentration of oxide that refined.4. It is shown that in superalloys Inkonel 52 in the alloy Inkonel was hit with a 52-MSS shenym content of Nb and Mo local ordering Cr destroyed at temperatures of 200 househo-lyzu ?S and it may be the reason for the sharp increase in ductility Inkonel 52 MSS.5. In the crystallization of amorphous metallic glass state Vitreloy-1 containing Be, recorded gradual growth and Young's modulus maxima due to structural re-creation, ranging from the glass transition temperature (325 oC) to the secondary crystallization temperature (460 oC). At 200 ° C in a partially zakrystalizovanomu alloy Vitreloy-1 q-tion peak of internal friction, interfacial about nature.KEY WORDS: internal friction, granular structure, amorphous structure, metals and alloys.
