Impamvu zo kugabanuka k'ubushyuhe buke bw'imiyoboro ikonje

Ubukonje bukonje (cyangwa ubushyuhe buke bwo kwishyiriraho)imbeho ikonjemugihe cyo gukoreshwa kigaragazwa nubukomezi brittleness ubushyuhe bwinzibacyuho Tc.Tc y'icyuma gifite isuku nyinshi (0.01% C) iri kuri -100C, kandi munsi yubushyuhe, iba imeze nabi.Ibintu byinshi bivangavanze mubukonje buzengurutswe neza ibyuma byicyuma byongera ubukana bwubukonje bwubushyuhe bwinzibacyuho yubukonje bukabije bwimiyoboro yicyuma, byongera ubukonje bwubukonje.Iyo kuvunika kwangirika kugaragara hejuru yubushyuhe bwicyumba, kuvunika hejuru yubukonje buzengurutswe neza nicyuma cyicyuma nicyuma kijimye, mugihe iyo kuvunika gucitse bibaye mubushyuhe buke, ni ukuvunika.

Impamvu yubushyuhe buke bwo gukonjesha imbeho ikonje ni:

.

(2) Dislocations nyinshi zegeranye zikora microcrack kumupaka wingano.

.010% 26gt, hamwe na microcrack imeze nk'umugozi ushobora gutobora indege ya clavage.

Ibintu bigira ingaruka ku bukonje bwubukonje bwimbeho bukonje burimo:

(1) Igisubizo gikomeye gishimangira ibintu.Fosifore yongerera ubukana ubushyuhe bwinzibacyuho cyane;Hariho na molybdenum, titanium, na vanadium;Iyo ibirimo ari bike, ingaruka ntizihambaye, mugihe iyo ibirimo ari byinshi, ibintu byongera ubukana bwubushyuhe bwinzibacyuho harimo silikoni, chromium, numuringa.Ibintu bigabanya ubukana bwubushyuhe bwinzibacyuho harimo nikel, nibintu bigabanuka mbere hanyuma bikongerera ubukana ubukana bwubushyuhe bwinzibacyuho harimo manganese.

(2) Ibintu bigize icyiciro cya kabiri.Ikintu cyingenzi muburyo bwo kongera ubukonje bwubukonje bwimbeho ikonje neza hamwe nicyiciro cya kabiri ni karubone.Mugihe ibyuka bya karubone mubukonje buzengurutse neza ibyuma byicyuma byiyongera, ibintu bya pearlite mubukonje buzengurutse neza ibyuma byicyuma byiyongera.Ugereranije, kuri buri 1% kwiyongera kwijwi rya pearlite, ubukana bwubukonje bwubushyuhe bwiyongera kuri 2,2 ℃ ugereranije.

(3) Ingaruka yibirimo bya karubone kuburiganya bwa ferritic pearlite.Kwiyongera kubintu bya microalloying nka titanium, niobium, na vanadium bigizwe na nitride cyangwa karubonitide, bigatuma kwiyongera k'ubushyuhe bukabije bwinzibacyuho yubukonje bukabije bwimiyoboro ikonje.

.Gutunganya ingano ingano bigabanya ubukonje bwubukonje mu mbeho ikonje neza neza imiyoboro yicyuma, nuburyo bukoreshwa cyane.
