Kugabanuka (bizwi kandi nk'ibice cyangwa ibice) nikibazo gisanzwe kandi kigira ingaruka mubikorwa byo guhimba. Kugabanuka ntibigabanya gusa imbaraga nigihe kirekire cyibigize impimbano ahubwo binongera ibiciro byumusaruro. Kugirango hamenyekane ubuziranenge bwibice byahimbwe, ni ngombwa kumva impamvu zitera kugabanuka, ingamba zo gukumira, nuburyo bwiza bwo kuyobora.
Impamvu zo Kugabanuka
Kugabanuka kugabanuka mubisanzwe bifitanye isano nibi bikurikira:
- Inhomogeneité yibikoresho: Ibigize imiti idahwitse cyangwa inenge zimbere mubikoresho fatizo bishobora gutera kugabanuka mugihe cyo guhimba.
- Kugenzura Ubushyuhe budakwiye: Kugenzura ubushyuhe budahagije mugihe cyo guhimba, cyane cyane igipimo cyo gushyushya no gukonjesha kutaringaniye, birashobora gutuma umuntu ahangayikishwa cyane nibikoresho, bikaviramo kugabanuka.
- Gutunganya Ibibazo bya Tekinike: Gushiraho nabi ibipimo byo gutunganya (nkumuvuduko wo guhindura ibintu hamwe nigitutu) mugihe cyo guhimba nabyo bishobora gutera kugabanuka.
- Ibikoresho no Gupfa Ibibazo: Ibikoresho byateguwe nabi cyangwa byambarwa cyane kandi bipfa birashobora gutera igabanywa ridahwitse kuruhande rwimpimbano, biganisha ku kugabanuka.
Uburyo bwo kwirinda kugabanuka
Nubwo kugabanuka bidashobora kwirindwa rwose mugikorwa cyo guhimba, uburyo bukurikira burashobora kugabanya cyane ibibaho:
Guhitamo Ibikoresho no Kuvura: Guhitamo ibikoresho byujuje ubuziranenge, bihurijwe hamwe kandi ugakora imyiteguro ikwiye (nka annealing na homogenisation) mbere yo guhimba bishobora kugabanya inenge zimbere.
Gutezimbere Ubushyuhe: Kugenzura cyane igipimo cyo gushyushya no gukonjesha mugihe cyo kwibeshya kugirango habeho no gukwirakwiza ubushyuhe no kugabanya imihangayiko yimbere. Ubuhanga nko gushyushya ibyiciro no gukonjesha buhoro birashobora kugabanya ubushyuhe bwa gradients.
Kunoza tekinike yo gutunganya: Gushiraho muburyo bwiza ibipimo byo gutunganya, nkumuvuduko wo guhindura umuvuduko nigitutu, kugirango wirinde guhindagurika gukabije no guhangayikishwa cyane. Kwigana kwinshi nubushakashatsi bwubushakashatsi burashobora gufasha guhuza ibipimo.
Igikoresho gishyize mu gaciro no gupfa Igishushanyo: Gutegura ibikoresho kandi bipfa kugirango habeho no kugabanura imihangayiko mugihe cyo guhimba. Kugenzura buri gihe no gusimbuza impfu zambaye cyane birashobora gukomeza gutunganya neza.
Uburyo bwo gucunga Shrinkage
Iyo kugabanuka bimaze kuba, uburyo bwo gucunga igihe kandi bunoze burashobora kugabanya ingaruka zabyo kubwiza bwibihimbano:
Kuvura Ubushyuhe: Gukoresha uburyo bwo kuvura ubushyuhe nka annealing hamwe nibisanzwe kugirango ukureho imihangayiko y'imbere iterwa no kugabanuka no kunoza ubukana n'imbaraga z'igice cyahimbwe.
Uburyo bwo gusana: Kubice bito byo kugabanuka, tekinoroji yo gusana nko gusudira no kongeramo ibikoresho irashobora gukoreshwa. Nyamara, ubu buryo busaba ubuhanga buhanitse bwo gukora kandi burashobora kugira ingaruka mubikorwa rusange byigice cyahimbwe.
Kugenzura Ubuziranenge no Kugenzura: Gukoresha uburyo bwo kwipimisha budasenya nko gupima ultrasonic na X-ray kugenzura kugirango umenye kandi ukureho ibice byahimbwe bigabanuka cyane, byemeze neza ibicuruzwa byanyuma.
IV. Umwanzuro
Kugabanuka mubikorwa byo guhimba ntibishobora kwirindwa rwose, ariko binyuze muguhitamo ibikoresho bifatika, kugenzura neza ubushyuhe, tekinoroji yo gutunganya neza, hamwe nibikoresho byateguwe neza hanyuma bipfa, ibibaho birashobora kugabanuka cyane. Byongeye kandi, kuvura ubushyuhe, tekinike yo gusana, hamwe nubugenzuzi bufite ireme birashobora gucunga neza kugabanuka kwariho, kwemeza ubwiza nigikorwa cyibice byahimbwe. Gukemura no gucunga ibibazo byo kugabanuka mubikorwa byo guhimba nibyingenzi kugirango hamenyekane ubuziranenge bwibicuruzwa, kuzamura umusaruro, no kugabanya ibiciro. Kunywa (bizwi kandi ko ari ibice cyangwa ibice) nikibazo gisanzwe kandi kigira ingaruka mubikorwa byo guhimba. Kugabanuka ntibigabanya gusa imbaraga nigihe kirekire cyibigize impimbano ahubwo binongera ibiciro byumusaruro. Kugirango hamenyekane ubuziranenge bwibice byahimbwe, ni ngombwa kumva impamvu zitera kugabanuka, ingamba zo gukumira, nuburyo bwiza bwo kuyobora.
