Cov hlau lead
Cov hmoov txhuas tsis yog yaj hauv tooj dag, thiab muab faib rau ntawm cov ciam teb hauv lub xeev dawb plasmas. Raws li nws lub koom haum, muaj ob hom hlau lead: thiab ( + ). txhuas tooj dag muaj tsawg plasticity ntawm qhov kub thiab txias vim muaj kev phom sij ntawm cov hlau lead, yog li nws tsuas yog txias deformed lossis kub extruded. ( + ) txhuas tooj dag muaj cov yas zoo ntawm qhov kub thiab txias tuaj yeem ua rau forged.
Tin tooj dag
Ntxiv tin rau hauv tooj dag, tuaj yeem txhim kho cov cua sov ntawm cov hlau, tshwj xeeb tshaj yog txhawm rau txhim kho lub peev xwm tiv thaiv corrosion ntawm seawater, yog li tin tooj dag muaj "naval tooj dag".
Tin tuaj yeem yaj mus rau hauv cov khoom siv tooj liab, cov tshuaj muaj zog ntxiv zog. Tab sis nrog kev nce ntawm cov ntsiab lus tin, cov hlau yuav tshwm sim r theem (CuZnSn tebchaw), tsis zoo rau cov yas deformation ntawm cov hlau, yog li cov ntsiab lus tin ntawm tooj dag feem ntau yog nyob rau hauv ntau ntawm 0. 5% mus rau 1.5%.
Feem ntau siv cov tooj dag yog HSn70-1, HSn62-1, HSn60-1 thiab lwm yam. Lub qub yog alpha alloy nrog high plasticity thiab tuaj yeem ua txias thiab kub siab machined. Ob qib tom kawg ntawm cov alloys muaj (+) ob-theem lub koom haum, thiab feem ntau me me ntawm r theem, chav tsev kub plasticity tsis siab, tuaj yeem tsuas yog deformed hauv lub xeev kub.
Manganese tooj dag
Manganese muaj ib tug loj solubility nyob rau hauv cov khoom tooj dag. Qhov sib ntxiv ntawm 1% mus rau 4% ntawm manganese hauv tooj dag tuaj yeem txhim kho lub zog thiab corrosion tsis kam ntawm cov hlau tsis txo nws cov yas.
Manganese tooj dag muaj (+) lub koom haum, feem ntau siv HMn58-2, txias thiab kub lub xeev siab ua haujlwm tau zoo heev.
Hlau tooj dag
Hlau tooj dag, hlau rau nag lossis daus ntawm hlau-nplua nuj theem hais, raws li cov nucleus thiab grain refinement, thiab muaj peev xwm tiv thaiv recrystallization grain loj hlob, yog li txhim kho cov neeg kho tshuab zog thiab txheej txheem kev ua tau zoo ntawm cov hlau. Hlau tooj dag nyob rau hauv cov ntsiab lus hlau feem ntau yog qis dua 1.5%, nws lub koom haum yog (+), muaj zog thiab tawv, siab kub plasticity zoo heev, kuj tuaj yeem deformed hauv lub xeev txias. Qib siv feem ntau yog Hfe59-1-1.
Nickel tooj dag
Nickel thiab tooj liab tuaj yeem tsim cov kev daws teeb meem txuas ntxiv, nthuav dav thaj tsam alpha theem. Ntxiv 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 ntawm cov tooj dag, ua kom cov nplej zoo dua.
HNi 65-5 npib tsib xee tooj dag muaj ib-theem-kev koom tes, chav tsev kub muaj cov yas zoo, kuj tuaj yeem deformed nyob rau hauv lub xeev kub, tab sis cov ntsiab lus ntawm impurity lead yuav tsum nruj me ntsis tswj, txwv tsis pub nws yuav hnyav deteriorate lub alloy kub. kev ua haujlwm.
