Mekhanicheskoe Legirovanie V Sistemakh "Zhelezo-khrom-metall-azot": Issledovanie Fazoobrazovaniya V Sistemakh Fe-cr-ni-n I Fe-cr-mn-n Pri ... Termoobrabotke Pavel Nikiforov Russian edition

Vysokokhromistye austenitnye stali i splavy na osnovezheleza ispol'zuyutsya kak korrozionnostoykie,kriogennye, zharoprochnye i malomagnitnye materialy. Krome togo, austenitnye stali s vysokim soderzhaniemmargantsa predstavlyayut interes kak materialypovyshennoy prochnosti. Odnim iz naibolee perspektivnykh austenitoobrazuyushchikhelementov yavlyaetsya azot, odnako vvedenie v splavbol'shikh kolichestv azota obychno sopryazheno s ryadomproblem. V to zhe vremya izvestno, chto tekhnologiyamekhanicheskogo legirovaniya pozvolyaet poluchat'sverkhravnovesnye tverdye rastvory, a takzhe okazyvaetintensivnoe vliyanie na strukturu materiala. V svyazi setim, dannaya rabota posvyashchena polucheniyumekhanolegirovannykh poroshkov sistem Fe-Cr-Ni-N iFe-Cr-Mn-N, issledovaniyu ikh fazovogo sostava,polucheniyu kompaktnykh obraztsov iz poluchennykh poroshkovi issledovaniyu mikrostruktury i raspredeleniyaelementov v poluchennykh obraztsakh. Dlya nauchnykh sotrudnikov, rabotayushchikh v oblastyakhporoshkovoy metallurgii, mekhanicheskogo legirovaniya iaustenitnykh staley, a takzhe dlya aspirantov istudentov sootvetstvuyushchikh spetsial'nostey.
