I-high-pressure alloy pipe deformation yokuqinisa isebenzisa indlela yokuguqulwa kokuqiniswa kwensimbi.Okwaziwa nangokuthi ukuqina kohlobo noma ukuqina komsebenzi.Amandla ezinto ezibonakalayo ku-macro (noma yonke) amandla okumelana nokuguquguquka (noma ukucindezeleka kokugeleza).Ukuqina yikhono lempahla yokumelana nokuguqulwa kwepulasitiki okwenziwe kwasendaweni (noma ngabe ubulukhuni obuncane, ubulukhuni be-Vickers, ubulukhuni be-Rockwell noma ubulukhuni be-Brinell).Zombili zinobudlelwano obuhambelanayo obufanayo ezimweni eziningi.Amandla ezinto ezibonakalayo, ukumelana okukhulu nokuguqulwa kwepulasitiki, ukuphakama kobulukhuni.Ngokuphambene, ukuphakama kokuqina kwempahla, impahla ingase ibe ngenxa yokwanda kwe-brittleness, amandla ayo awabonakali ngokugcwele kumanani anjalo wenkomba yamandla ayiphezulu.
Isikhathi eside ngaphansi kokwelashwa okushisa, kanye nokusetshenziswa kwempahla emazingeni okushisa ngaphansi kwezinga lokushisa le-recrystallization ye-high-pressure alloy pipe steel material (njenge-low-carbon low-alloy steel), ngokuvamile sebenzisa amakhaza (ukuguqulwa okubandayo) ukuthi ngokusebenzisa ukuqinisa deformation ukuthuthukisa amandla.Ngakho-ke, i-deformation eqinisa i-essence isesimweni sokushisa kabusha kwe-recrystallization yento ekuguquguqukeni okubandayo okulandelayo, ngezinga lokuguquguquka (ubunzima) liyakhuphuka, okuholela ekukhuleni okukhulu kokuhlakazeka (ama-crystal defects), ukuphakama kwe-dislocation ku-crystal kuphezulu. , Izinga elikhulu lokuthuthuka, okungukuthi ingcindezi ephezulu yokugeleza.Ngemuva kokugeleza kwe-deformation ukucindezeleka kwensimbi akufanele kulingane ngaphambi kokucindezeleka kokugeleza kwe-deformation kanye nokuguquguquka okukhulayo kuqinisa ukugeleza kwengcindezi.Ukusetshenziswa kokuqinisa ukuguquguquka ukuze kuzuzwe imikhiqizo yensimbi enamandla aphezulu, okuvamile insimbi yensimbi enekhabhoni ephezulu edonsa insimbi ebandayo kanye nensimbi ephansi ene-carbon low-alloy duplex steel steel cold-drawn steel wire.
Ngokukhula kwezinga lokuguquguquka, amandla ezinto ezibonakalayo nokuqina kuya phezulu nangaphezulu, kepha i-ductility yayo kanye nokuqina kwayo kuvame ukwehla futhi kunciphe, kuhlakazeke kakhulu, okudinga kanzima ukuthatha izinyathelo ezifanele zokuthuthukisa isimo.Ingaphakathi elingeniswa esigabeni sokuguqulwa kwesigaba se-martensitic ukupholisa ukuqina, ingqikithi yalo yomzimba, liphinde libe lokuqiniswa kwe-deformation, kodwa kulokhu hhayi kusukela ekuguqulweni kwangaphandle, kodwa inqubo yokuguqulwa kwe-martensitic kusuka ku-crystal High-density indawo ngokwayo i-shear eyenziwe ngephutha.
