Cov hlau lead
Lead yog insoluble nyob rau hauv tooj dag thiab muab faib rau ntawm grain ciam teb nyob rau hauv lub xeev ntawm dawb hais. Raws li nws lub koom haum, txhuas txhuas muaj ob hom: α thiab (α + β). Vim muaj kev phom sij ntawm cov hlau lead, alpha-lead tooj dag muaj qhov kub tsis tshua muaj siab plasticity, yog li nws tsuas yog txias deformed lossis kub extruded. (α + β) Lead tooj dag muaj cov yas zoo ntawm qhov kub thiab txias thiab tuaj yeem ua rau forged.
Tin tooj dag
Ntxiv cov tin rau tooj dag tuaj yeem txhim kho cov cua sov ntawm cov hlau, tshwj xeeb tshaj yog muaj peev xwm tiv taus dej hiav txwv corrosion, yog li tin tooj dag hu ua "navy brass".
Tin tuaj yeem yaj mus rau hauv cov khoom siv tooj liab-raws li kev daws teeb meem thiab ua si ib qho kev daws teeb meem ntxiv zog. Tab sis nrog kev nce ntawm cov ntsiab lus tin, brittle r-theem (CuZnSn compound) yuav tshwm sim hauv cov hlau, uas tsis tsim nyog rau cov yas deformation ntawm cov hlau, yog li cov ntsiab lus tin ntawm tooj dag feem ntau nyob rau hauv thaj tsam ntawm 0.5% rau 1.5%.
Feem ntau siv tin brasses yog HSn70-1, HSn62-1, HSn60-1 thiab lwm yam. Cov qub yog alpha alloy, uas muaj cov yas siab thiab tuaj yeem ua tiav los ntawm kev txias thiab kub siab. Cov alloys ntawm ob qib tom qab muaj ib tug (α + β) ob-theem qauv, thiab ib tug me me ntawm r-theem yog feem ntau tam sim no, thiab lub plasticity ntawm chav tsev kub tsis siab, thiab nws tsuas yog deformed nyob rau hauv lub kub. xeev.
Manganese tooj dag
Manganese muaj ntau dua solubility hauv cov khoom tooj dag. Ntxiv 1% mus rau 4% ntawm manganese rau tooj dag tuaj yeem ua rau muaj zog thiab corrosion tsis kam ntawm cov hlau tsis txo nws cov yas.
Manganese tooj dag muaj cov qauv (α + β), thiab HMn58-2 feem ntau yog siv, thiab nws cov kev ua haujlwm siab nyob rau hauv qhov txias thiab kub yog qhov zoo heev.
Hlau tooj dag
Nyob rau hauv hlau tooj dag, hlau precipitates nrog hlau-nplua nuj theem hais, uas ua hauj lwm raws li siv lead ua nuclei rau refine cov siv lead ua nplej thiab tiv thaiv kev loj hlob ntawm recrystallized nplej, yog li txhim kho cov neeg kho tshuab zog thiab txheej txheem kev ua tau zoo ntawm cov hlau. Cov ntsiab lus hlau hauv hlau tooj dag feem ntau qis dua 1.5%, nws cov qauv yog (α + β), nws muaj zog thiab tawv, zoo plasticity ntawm qhov kub thiab txias, thiab tuaj yeem deformed nyob rau hauv txias txias. Qib siv feem ntau yog Hfe59-1-1.
Nickel tooj dag
Nickel thiab tooj liab tuaj yeem tsim cov kev daws teeb meem tas mus li, uas nthuav dav rau thaj tsam α-theem. Qhov sib ntxiv ntawm npib tsib xee rau tooj dag tuaj yeem txhim kho qhov corrosion kuj ntawm tooj dag nyob rau hauv qhov chaw thiab dej hiav txwv. Nickel kuj tseem tuaj yeem ua kom qhov kub thiab txias recrystallization ntawm tooj dag thiab txhawb kev tsim cov nplej zoo.
HNi65-5 npib tsib xee tooj dag muaj ib theem α qauv, uas muaj cov yas zoo nyob rau hauv chav tsev kub thiab tuaj yeem deformed nyob rau hauv kub kub. Txawm li cas los xij, cov ntsiab lus ntawm impurity txhuas yuav tsum tau tswj nruj me ntsis, los yog nws yuav ua rau lub cev kub ua haujlwm ntawm cov hlau.
