BT20 Titanium phaj

BT20 titanium phaj yog ib qho ntawm cov titanium daim hlau ua los ntawm peb lub tuam txhab. Peb tseem tuaj yeem ua thiab kho lwm yam ntau yam titanium alloy semi-tiav thiab tiav cov ntaub ntawv thiab cov khoom lag luam rau koj. BT20 yog ib qho ze ntawm - - hom titanium alloy, thiab kev daws teeb meem ntxiv dag zog los ntawm -stabilizing lub ntsiab Al yog lub ntsiab txhawb zog ntawm cov hlau no. Cov ntsiab lus nruab nrab Zr thiab -stable ntsiab Mo thiab V tau ntxiv rau cov hlau los txhim kho kev ua haujlwm. Qhov sib npaug Al sib npaug ntawm cov hlau yog 6.58%, uas yog nyob ze ntawm - - hom titanium alloy nrog siab Al sib npaug, yog li nws tsis tsuas yog muaj lub zog kub zoo thiab weldability ntawm hom titanium alloy, tab sis kuj muaj ib qho txheej txheem plasticity ze rau ntawm ib qho - - hom titanium alloy. . Lub alloy muaj nruab nrab ntawm chav tsev kub thiab kub siab zog, zoo thermal stability thiab weldability.

1. BT20 titanium muaj lub zog siab, uas yog vim muaj lub zog zoo heev thiab lub zog tensile ntawm titanium alloy, uas ua rau nws muaj kev ua siab ntev thiab lub zog nyob rau hauv high-strength thiab high-temperature ib puag ncig. Yog li ntawd, nws tau dhau los ua cov khoom ntawm kev xaiv rau kev tsim khoom siv high-end xws li aircraft, missiles, thiab nkoj.

2. BT20 muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem hloov kho raws li qhov yuav tsum tau muaj ntawm qhov chaw sib txawv. Nws tuaj yeem siv rau lub sijhawm ntev yam tsis muaj corroded nyob rau hauv hnyav ib puag ncig xws li dej hiav txwv, muaj zog acid, thiab muaj zog alkali, thiaj li yuav xyuas kom meej tias cov cuab yeej tswj kev ua haujlwm zoo thiab kev ua haujlwm tau ntev. Yog li ntawd, nws yog dav siv nyob rau hauv kev lag luam xws li tshuaj lom neeg kev lag luam, marine thiab roj extraction.

3. BT20 titanium muaj cov yas zoo thiab tuaj yeem ua tiav los ntawm ntau txoj hauv kev xws li kev ua haujlwm kub thiab kev ua haujlwm txias. Vim yog lub plasticity ntawm titanium alloy, nws tuaj yeem ua tiav rau hauv ntau yam duab, xws li daim hlau, cov kav dej, thiab lwm yam, uas yog qhov tsim nyog rau kev tsim cov khoom siv kho mob, cov khoom ua si thiab lwm yam.

Lub hardness HB (d) ntawm hom no tom qab annealing yog 3.3 ~ 3.6, lub zog tensile yog 900MPa ~ 1130MPa, lub zog tensile ntawm 500 degree yog 570MPa, thiab tuaj yeem khaws cia ntawm 470MPa rau 50h tsis tu ncua, thiab cov khoom siv ceev yog me me thiab lub zog tshwj xeeb yog siab. , Zoo heev corrosion thiab oxidation kuj. Cov uas ua tau raws li cov khoom saum toj no tuaj yeem xaiv tau.

BT20 alloy titanium tuaj yeem tsim los ntawm ntau yam kev sib tsoo thiab kev ua haujlwm xws li lub tshuab nqus tsev arc remelting (VAR), plasma arc melting (PAM), electron beam melting (EBM) thiab hmoov metallurgy (PM). VAR yog txoj kev siv ntau tshaj plaws rau kev tsim BT20 titanium phaj, uas yog lub npe hu rau kev tsim cov ntaub ntawv uas muaj purity siab, tsis muaj kuab paug thiab zoo heev mechanical zog.

BT20 titanium phaj feem ntau dhau los ntawm kev kho cua sov, nrog rau kev sib tsoo, kev kho tshuaj thiab kev laus.

1. Cov txheej txheem annealing yog siv los txo cov kev ntxhov siab hauv cov khoom uas yuav tau tsim thaum lub sij hawm ua. Qhov no yog ua tiav los ntawm cua sov cov khoom mus rau qhov kub thiab txias rau qee lub sijhawm, thiab tom qab ntawd maj mam txias cov khoom mus rau chav sov.

2. Cov txheej txheem kev daws teeb meem suav nrog cov khoom siv cua sov kom siab rau lub sijhawm kom yaj cov theem ob uas tau tsim thaum lub sijhawm ua haujlwm. Cov khoom yog ces txias rau chav tsev kub ntawm tus nqi tswj.

3. Cov kauj ruam kawg hauv kev kho cua sov yog kev laus, uas suav nrog cov khoom siv cua sov rau ib lub sijhawm tshwj xeeb los txhawb cov nag lossis daus ntawm theem nrab thiab ua tiav cov khoom siv kho mob uas xav tau.

BT20 titanium alloy tau siv dav hauv kev tsim khoom ntawm cov khoom siv thauj khoom ntawm cov dav hlau thiab cov cav, tshwj xeeb tshaj yog welded load-bearing structural qhov chaw. Cov qib no yog siv los tsim cov khoom uas tsis yog tus qauv uas yuav tsum muaj qhov kub thiab txias, xws li cov txiv ntoo uas tsis yog cov qauv paj, ntsaws, cov tsho hauv qab, cov pob qij txha, cov phaj siab, nuv pins, ntsia hlau ntsaws, ntsaws, cov yeeb nkab txuas, lub luj tshib, thiab lwm yam.

BT20 alloy nyob rau hauv peb lub tuam txhab muaj xws li nyias phaj, tuab phaj, dov bar, forged bar, tuag forging, forging, extruded profile, welded nplhaib daim, ib lub nplhaib dov daim thiab casting.
