Kuvura ubushyuhe budakwiye imiyoboro idafite ibyuma irashobora gutera byoroshye urukurikirane rwibibazo byumusaruro, bigatuma ubwiza bwibicuruzwa byangirika cyane bigahinduka ibisigazwa.Kwirinda amakosa asanzwe mugihe cyo kuvura ubushyuhe bivuze kuzigama amafaranga.Ni ibihe bibazo twakagombye kwibandaho mu gukumira mugihe cyo gutunganya ubushyuhe?Reka turebe ibibazo bikunze kugaragara mugutunganya ubushyuhe bwimiyoboro idafite ibyuma:
Structure Imiyoboro y'ibyuma itujuje ibyangombwa n'imikorere: ibintu bitatu biterwa no gufata ubushyuhe budakwiye (T, t, uburyo bwo gukonjesha).
Imiterere ya Wei: Ibinyampeke bito A byakozwe nicyuma mugihe cy'ubushyuhe bwo hejuru ubushyuhe bugizwe nuburyo flake F ikwirakwizwa kuri P iyo ikonje.Nuburyo bushyushye kandi bubabaza imikorere rusange yicyuma.By'umwihariko, ubushyuhe busanzwe bwibyuma buragabanuka kandi ubwinshi bwiyongera.
Imiterere ya W yoroheje irashobora gukurwaho mubisanzwe mubushyuhe bukwiye, mugihe imiterere ya W iremereye irashobora gukurwaho nubusanzwe busanzwe.Ubushyuhe bwa kabiri busanzwe buri hejuru, naho ubushyuhe bwa kabiri busanzwe buri hasi.Ibinyampeke.
Igishushanyo mbonera cya FC ni ishingiro ryingenzi ryo gutegura ubushyuhe bwo kuvura ubushyuhe bwicyuma.Niyo shingiro ryo kwiga ibihimbano, imiterere ya metallografiya, hamwe nimiterere ya kristu ya FC kuringaniza, igishushanyo mbonera cyubushyuhe bwa supercooling A (igishushanyo cya TTT) hamwe no guhora gukonjesha guhindagurika kwa supercooling A. Imbonerahamwe (CCT imbonerahamwe) ni ishingiro ryingenzi yo gukora ubushyuhe bukonje bwo kuvura ubushyuhe.
Ibipimo by'umuyoboro w'icyuma ntujuje ibisabwa: diameter yo hanze, ovality, na curvature ntibishobora kwihanganira.
Impinduka mumurambararo winyuma wumuyoboro wibyuma akenshi bibaho mugihe cyo kuzimya, kandi diameter yinyuma yumuyoboro wibyuma iriyongera kubera ihinduka ryijwi (biterwa nimpinduka zubatswe).Ingano yubunini ikunze kongerwaho nyuma yubushyuhe.
Imihindagurikire yicyuma cya ovality: Impera yimiyoboro yicyuma ahanini ni diameter nini ya diameter yoroheje.
Umuyoboro w'icyuma wunamye: uterwa no gushyuha no gukonjesha imiyoboro y'ibyuma, birashobora gukemurwa no kugorora.Ku miyoboro y'ibyuma ifite ibisabwa byihariye, hagomba gukoreshwa inzira igororotse (hafi 550 ° C).
RaIbice hejuru yimiyoboro yicyuma: biterwa no gushyuha cyane cyangwa umuvuduko ukonje hamwe nubushyuhe bukabije bwumuriro.
Kugabanya ibice byo gutunganya ubushyuhe mu miyoboro yicyuma, kuruhande rumwe, sisitemu yo gushyushya hamwe na sisitemu yo gukonjesha umuyoboro wibyuma bigomba gutegurwa ukurikije ubwoko bwibyuma, kandi hagomba gutoranywa uburyo bukwiye bwo kuzimya;kurundi ruhande, umuyoboro wicyuma uzimye ugomba guhindurwa cyangwa gufatirwa vuba bishoboka kugirango ukureho imihangayiko.
Gushushanya cyangwa kwangirika gukabije hejuru yumuyoboro wibyuma: biterwa no kunyerera ugereranije hagati yicyuma nicyuma cyakazi, ibikoresho, hamwe nizunguruka.
PUmuyoboro w'icyuma urimo okiside, karubone, ubushyuhe bwinshi, cyangwa burashya.Byatewe na T ↑, t ↑.
Ox Okiside yubuso bwumuriro wibyuma ukoreshwa na gaze ikingira: Itanura ryo gushyushya ntirifunze neza kandi umwuka winjira mu itanura.Ibigize gaze yitanura ntibihinduka.Birakenewe gushimangira kugenzura ubuziranenge bwibintu byose byo gushyushya umuyoboro ubusa (umuyoboro wibyuma).
