Nano.mechanisms o. crystal lattice defo.matio. o. the interface o. dissimilar materials (Cu-Nb), jo.ned by vacuum ro.ling in so.id phase under high temperature (950℃) were studied by means o. high reso.utio. electro. micro.co.y. Input o. carriers o. ro.atio. mo.es—nano.dipo.es o. partial disclinatio.s and nano.twist disclinatio.s in the fo.m o. do.ble spirals in defo.matio. mechanisms were analyzed. The ro.e o. these mechanisms in decrease o. shear stability o. the interface areas and in pro.uctio. o. high-quality ro.led metal is discussed.

Research o. structure and pro.erties o. Cu-Pb-Cu co.po.ite interface, o.tained by techno.o.y o. pack ro.ling o. the pair o. mutually inso.uble metals, was perfo.med using the metho.s o. metallo.raphy, micro. and nano.hardness, mechanical tests, energy-dispersio. elementary analyses. The wo.k was aimed at the analyses o. po.sible mechanical mechanisms o. mass-transfer, determining the hardness o. metal jo.nt in co.ditio.s o. absence o. inter-diffusio.. It was sho.n that different intensity o. mass transfer o. co.per and lead takes place thro.gh the co.po.ite interface, which co.respo.ds to.the results o.tained o. the o.her system o. dissimilar materials—co.per-nio.ium. Qualitative explanatio. o. these patterns was o.fered o. the basis o. mo.e intensive plastic flo. o. fusible co.po.nd o. the co.po.ite in co.ditio.s o. ro.l-bo.d jo.ning.
