Ubukonje bukonje bwa Tube
Porogaramu nyamukuru: Imodoka, ipikipiki, ibikoresho bya firigo, ibice bya hydraulic, ibyuma, silinderi ya pneumatike, nabandi bakiriya bafite ibisabwa cyane kugirango imiyoboro yicyuma ibe nziza, ubworoherane, isuku, nibikoresho bya mashini.
1, Ikintu nyamukuru kiranga umuyoboro usanzwe udafite icyuma ni uko idafite icyuma gisudira kandi gishobora kwihanganira umuvuduko mwinshi.Ibicuruzwa birashobora kuba bibi cyane nkibishishwa cyangwa ibice bikonje bikonje.
2, Umuyoboro ukonje ushushanyije neza ni umwobo w'imbere, kandi ubunini bw'urukuta rw'inyuma bufite kwihanganira gukabije no gukomera, kandi ubusobanuro buri hejuru cyane.
Ubukonje bukonje (cyangwa ubushyuhe bwo hasi bwubushyuhe bwo hasi) bwubukonje buzengurutswe neza neza umuyoboro wicyuma ugaragazwa nubukonje-ubukonje bwubushyuhe Tc.Icyuma cyiza cyane (0.01% C) gifite Tc ya 100C, kandi cyanditse rwose munsi yubushyuhe.Ibyinshi mubintu bivangavanze mubukonje buzengurutswe neza nicyuma cyumucyo cyicyuma cyizamura ubukonje-buke bwinzibacyuho yubushyuhe bwimbeho ikonje kandi ikongerera ubukonje bukabije.Iyo kuvunika kwimyanya iri hejuru yubushyuhe bwicyumba, kuvunika kwubukonje buzengurutswe neza nicyuma cyoroshye nicyuma cyoroshye, kandi iyo cyacitse intege mubushyuhe buke, ni ukuvunika.
Impamvu ziterwa n'ubushyuhe buke bwo gukonjesha gukonje neza neza umuyoboro w'icyuma ni:
.
(2) Dislocations nyinshi zacometse zikora microcrack kumupaka wingano.
.
Ibintu byongera ubukonje bwubukonje bwimbeho ikonje neza ni:
(1) Igisubizo gikomeye gishimangira ikintu.Fosifore yongerera ubukana-buke ubushyuhe bwinzibacyuho ikomeye;hari na molybdenum, titanium na vanadium;iyo ibirimo ari bike, bigira ingaruka nke, ariko iyo ibirimo ari byinshi, ibintu byongera ubukana-buke bwinzibacyuho ni silikoni, chromium n'umuringa;gabanya ubukana-brittleness Ubushyuhe bwo guhinduka ni nikel, naho ubukana-buvunagura ubushyuhe ni manganese.
(2) Ibintu bigize icyiciro cya kabiri.Ikintu cyingenzi kubintu bikonje byubukonje bwimbeho ikonje neza nicyuma cya kabiri ni karubone.Hamwe no kwiyongera kwa karubone mu mbeho ikonje ikonje neza, ibyuma bya pearlite mu mbeho ikonje neza neza imiyoboro yicyuma yiyongera, hamwe no kwiyongera kwa 1% yubunini bwa pearlite.Ubushyuhe bukabije bwo kugabanuka bwiyongereyeho 2,2 ° C ugereranije.Igishushanyo cya 2 cyerekana ingaruka zibirimo bya karubone muri ferrite-pearlite ibyuma kuri brittleness.Kwiyongera kwa microalloying ibintu nka titanium, niobium na vanadium bizakora nitride itatanye cyangwa karubone, bigatuma ubushyuhe bukabije bwinzibacyuho yubukonje bukabije bwimiyoboro ikonje izamuka.
(3) Ingano y'ibinyampeke igira ingaruka ku bushyuhe-bworoshye ubushyuhe bwinzibacyuho.Nkuko ibinyampeke bigenda byiyongera, ubukana-bugabanutse ubushyuhe bwiyongera.Gutunganya ibinyampeke bigabanya ubukonje bukabije bwubukonje bwimbeho ikonje neza, nuburyo bukoreshwa cyane.
