Guhindura mumiterere ya chromium zirconium umuringa nyuma yo kuvura ubushyuhe

Nyuma yo gukemura gusaza kuvura, imvura nziza yumukara ikwirakwizwa cyane kumupaka wingano zachromium zirconium umuringa, kandi imvura nyinshi yumukara nayo ikwirakwizwa mubinyampeke, hamwe nubunini bwa microne nkeya.Mugihe ubushyuhe bugabanutse, umurongo wegera kuruhande rwumuringa, kandi gukomera kwayo ni 0.03% gusa kuri 400 ° C.Muri iki gihe, ibice bigize umuringa zirconium bigwa mu gisubizo gikomeye.Kubwibyo, chromium ifite umubiri wububiko bushingiye ku mubiri, chromium ifite imiterere yegeranye yuzuye ya mpande esheshatu, hamwe n'umuringa ufite icyerekezo gishingiye ku maso bisa nkaho bitagaragara ku bushyuhe bw'icyumba, ariko umuringa na chromium ntibishobora gukora ibice, mu gihe umuringa na zirconium bishobora gukora ibyiciro bitandukanye.Chromium na zirconium birashobora kandi gukora ibice bitandukanye byuzuzanya.Nyuma yo kuvura ubushyuhe, matrix ya chromium zirconium y'umuringa ni umuringa, naho icyiciro cyimvura nicyo gihuza intermetallic ya Cr phase na chromium.
Imbaraga zingana, zitanga imbaraga nubukomezi bwa chromium-zirconium-umuringa nyuma yo kuvura ubushyuhe byiyongera, kandi kuramba nyuma yo kuvunika kugabanuka.Chromium-zirconium-umuringa ikora igisubizo kirenze urugero mugihe gikemutse, kandi icyiciro cya kabiri hamwe nu muringa bivanwa mubisubizo bikomeye mugihe cyo gusaza.Imvura, icyiciro gishya cyo gukwirakwiza gushimangira.Icyiciro cya kabiri kiratatanye kandi kigabanywa muri matrix kugirango habeho umubano mwiza na matrix.Hariho ibintu byinshi bidahuye kuri coherent interface, itera kugoreka lattice, byongera ingufu za elastique zingutu zicyiciro cya interineti kandi bikazamura imbaraga, ubukana nubworoherane bwa alloy..Amashanyarazi ya chromium zirconium y'umuringa nyuma yo kuvura ubushyuhe ararenze ayo mbere yo kuvura ubushyuhe.Ukurikije inyigisho yibisubizo bikomeye bigoye, icyiciro cya elegitoronike cyicyuma gishaje kigenzurwa cyane nubushake bukomeye bwa matrix ikomeye.Ku bushyuhe bwicyumba, ibishishwa byibintu bivangwa mumuringa ni bito cyane.Mugihe cyo gusaza, ibintu hafi ya byose bivanze bikomeza kugwa muri matrike ya Cu, kandi ibikubiye mubintu bya solute mubisubizo bikomeye bigenda bigabanuka buhoro buhoro kugeza igihe igisubizo gikomeye kijya kuri materique yumuringa, bityo bikazamura amashanyarazi.
