Chrome zirconiumtooj liab yog ib yam ntawm cov khoom siv hlau, feem ntau yog siv rau hauv vuam ntawm machinery manufacturing kev lag luam. Chromium zirconium tooj liab tuaj yeem ntxiv dag zog rau hauv txoj kev hauv qab no.
1. Lub zog deformation
Lub mechanism ntawm txias deformation ntxiv dag zog rau chrome zirconium tooj liab yog tias dislocations tas li tsim thaum lub sij hawm deformation, qhov ceev ntawm dislocations nce, dislocations yog entangled nrog ib leeg, thiab nws yog ib qho nyuaj rau tsiv, uas ua rau lub deformation kuj thiab lub zog ua loj. Nyob rau tib lub sijhawm, qhov txo qis hauv conductivity vim cov duab tsis loj heev. Txoj kev ntxiv dag zog no feem ntau yog siv rau cov alloys ntawm cov yas zoo. Thaum ua hauj lwm hardening, cov hlau ua hauj lwm txias los yog yas deformation ntawm ib tug kub ntawm cov hlau recrystallization kub, yog li ua rau nws lub zog thiab hardness. Thaum cov hlau ua haujlwm txias yog rhuab mus rau qhov kub ntawm recrystallization, cov xim induced dislocation yog txo qis, yog li ntawd qhov tseeb feem ntau ntawm yav dhau los ntxiv dag zog poob lawm.
2. Cov kua nplaum ua kom muaj zog
Qhov tshwm sim uas chrome zirconium tooj liab tuaj yeem txhim kho lub zog thiab hardness ntawm cov hlau los ntawm kev ua kom cov ntsiab lus solute los ua cov kua nplaum yog hu ua cov tshuaj ntxiv dag zog. Cov khoom yaj yaj kub yuav plam feem ntau ntawm nws lub zog ntawm li 1/2 ntawm qhov kub thiab txias-tej theem kab kub.
3. Cov ciam teb ntxiv dag zog
Lub grain ciam teb ntxiv dag zog ntawm Cr, Zr thiab Cu yog qhov ntxiv dag zog ntawm cov ciam teb nplej tiv thaiv kev tsim ntawm kev txav mus los. Lwm cov xwm txheej zoo ib yam, qhov zoo dua cov nplej loj ntawm cov khoom siv hlau, ntau qhov ciam teb, qhov ntau dua qhov kub ntawm chav tsev.
4. Kev tiv thaiv nag lossis daus
Kev ua kom dej nag yog hais txog kev sib cais ntawm cov ntsiab lus solute rau hauv cov hlau matrix thiab tom qab ntawd khov sai heev los ua cov txheej txheem metastable saturated solid solutions: atomic segregation pawg lossis cov khoom ntawm cov tshuaj intermetallic yog tom qab ntawd tsim nyob rau hauv matrix thaum nag lossis daus kub kho.
Chrome zirconium tooj liab yog haum rau kev them nqi fittings ntawm fusion welders, tab sis feem ntau yog siv rau electroplating fittings.
