Titanium Alloy: Cov yam ntxwv, kev cov nyom cov nyom thiab yav tom ntej

Titanium alloy, cov khoom siv muaj lub zog siab, cov kws kho mob corrosion, ib txwm muaj kev xaiv dav hlau thiab cav tsim. Txawm li cas los xij, nws cov kev txom nyem Machinity tau ntev tau ntev tau qhov tseem ceeb txwv nws cov ntawv thov thoob plaws. Txawm li cas los xij, nrog kev nce qib nruam ntawm kev ua cov thev naus laus zis, daim ntawv thov teb ntawm titanium alloy tau muab dav hauv kev tsim cov khoom siv dav hlau ntawm cov dav hlau thiab cov qauv txheej txheem thav duab. Tom ntej no, peb yuav tshawb txog cov yam ntxwv tshwj xeeb ntawm cov alloys titanium thiab lawv cov khoom siv cuam tshuam ntsig txog lawv.

Cov yam ntxwv ntawm Titanium thiab titanium alloys
Titanium thiab titanium alloys qhia ntau yam ntxwv zoo, feem ntau yog suav nrog:

Lub zog siab thiab hardness: lub tensile lub zog ntawm titanium alloy yog ntau li 60% ntawm cov hlau, yog li nws muaj lub zog loj. Lub hardness ntawm annealed titanium alloy ncav cuag HRC 32-38, qhia nws lub hardness kom zoo dua.

Qes me Elastic Modulus: Elastic Modulus ntawm Annealed titanium alloy yog 1.078 × 10-1.176 × 1076 × 10mpa, uas yog li ib nrab ntawm cov hlau thiab stainless hlau. Cov yeeb yam no ua rau nws nyuaj dua thaum raug cuam tshuam.

Zoo heev thiab tsis tshua muaj kub ua tau kev ua tau zoo: titanium alloy tuaj yeem tswj hwm cov neeg kho cua sov zoo tshaj qhov ntawm txhuas ntau, thiab nws txoj haujlwm ntsuas kub yog dav. Kev ua haujlwm kub ntawm cov tshiab tshav kub-resistant titanium alloy tuaj yeem ncav cuag 550-600 degree. Hauv qhov chaw kub tsawg, lub zog ntawm titanium alloy yog txhim kho thaum tswj kev ua kom zoo, piv txwv li, nws tseem tuaj yeem tswj hwm kom nruj heev ntawm -253 degree.

Zoo heev corrosion: titanium tuaj yeem tsim cov yeeb yaj kiab tensanium oxide hauv cov huab cua hauv qab 550, nitric acid thiab sulfuric acid, thiab muaj zog alkali.

‡ Kev ua tau zoo ntawm titanium thiab titanium alloys
Thaum ua cov titanium alloys, nws cov yam ntxwv thiab cov yam ntxwv thaum txiav yuav tsum tau txiav txim siab. Nws raug nquahu kom siv cov cuab yeej carbide, xws li tungsten-cobalt a latural, vim hais tias ntawm nws qis tshuaj lom neeg nrog titanium alloy, zoo thermal conductivity thiab muaj zog siab. Rau kev sib quas ntus txiav ntawm kev nrawm nrawm, ultra-nplua-grain-grained carbide nrog cuam tshuam kev cuam tshuam tuaj yeem xaiv; Thaum High-ceev steel nrog kev ua tau zoo heev yog tsim nyog rau kev tsim thiab cov cuab yeej nyuaj.

▲ Cov txheej txheem txiav
Siv ib qho me me rake lub kaum sab xis thiab lub nraub qaum loj dua, uas tuaj yeem ua rau muaj kev sib tiv tauj ntawm lub ntsej muag thiab lub ntsej muag ua ntej ntawm kev ua haujlwm ntawm lub ntsej muag. Qhov dav ntawm cov ady ady ady ady adopts ARCC hloov pauv los txhim kho lub zog thiab tiv thaiv kom kub thiab chipping ntawm cov fab ntse. Nyob rau tib lub sijhawm, nws yog qhov tseem ceeb heev kom ua kom cov hniav ntse los xyuas kom cov leeg tshem tawm thiab tsis txhob chipping tshwm sim los ntawm cov chips. Thaum lub sij hawm txiav cov txheej txheem, ib txoj kev txiav qis dua yuav tsum tau xaiv los tiv thaiv qhov kev txiav ntawm qhov kub siab dhau. Tus nqi pub tau yuav tsum muaj qog. Ntau dhau yuav ua rau cov cuab yeej hlawv, thaum tsis tshua muaj zog yuav ua rau kev coj nruj vim yog cov hniav ua haujlwm hauv cov tawv tawv. Qhov kev txiav yuav tau teeb loj dua yog li ntawd cov lus ua haujlwm hauv qab no cov khoom tawv tawv, uas pab txhawm rau txhim kho lub durability txheej ntawm cov cuab yeej. Tsis tas li ntawd, lub txias txias yuav tsum tau siv txias rau cua txias thaum ua.

An Sib tsoo
Thaum txiav titanium alloy, vim tias qhov loj tiv thaiv kev txiav, cov txheej txheem system yuav tsum muaj qhov ruaj khov. Nyob rau tib lub sijhawm, txij li titanium alloy yog qhov yooj yim rau deform, lub zog clamping yuav tsum tsis txhob muaj ntau dhau ntawm kev ua tiav thaum tsim nyog.

Tsis tas li ntawd, Titanium Alloy ntsib ib txoj kev sib tw hauv kev sib tsoo. Nws cov tshuaj lom neeg yog nquag, thiab nws yog ib qho yooj yim los ua affinity thiab ua rau cov abrasives ntawm qhov kub, uas yuav ua rau muaj kev sib tsoo thiab ua kom muaj kev sib tsoo. Nyob rau tib lub sijhawm, sib tsoo cov ris tsho yuav tseem nce thaj chaw sib tsoo thiab ua rau qhov kub thiab txias, cuam tshuam rau qhov sib tsoo kom loj hlob, ua rau muaj kev sib tsoo thiab hlawv hluav taws xob. Ib qho ntxiv, lub zog siab thiab tawv ntawm titanium alloy kuj tseem ua rau nws nyuaj rau kev sib tsoo cov txheej txheem, nce kev sib tsoo thiab nce kev sib tsoo fais fab noj. Tsis tas li ntawd, qhov tsawg thermal conductivity thiab cov cua sov tsawg ntawm titanium alloy ua rau kev sib tsoo hauv qhov kub thiab kub ua rau muaj qhov kub thiab txias ntxiv rau qhov kub thiab txias ntawm qhov chaw sib tsoo.
▲ Extrusion Ua
Thaum cov extruding titanium thiab titanium alloys, nws yog qhov tsim nyog yuav kom ntseeg tau qhov kub extrusion yog siab txaus kom tiv thaiv qhov kub los tiv thaiv sai sai. Nyob rau tib lub sijhawm, lub sijhawm hu tau nruab nrab ntawm cov high-kub billet thiab kev tuag yuav tsum tau kom luv npaum li ntau tau, yog li nws raug pom zoo kom siv cov khoom siv kub tshiab-resistant. Thaum xa cov billet, qhov nrawm los ntawm cov cua sov hluav taws xob mus rau extrusion barrel tseem yuav tsum tau yoo mov txaus. Ib qho ntxiv, txij li cov hlau yuav paug tau los ntawm cov roj hauv cua sov thiab kev siv tshuaj tiv thaiv, tsim nyog tiv thaiv, tsim nyog tiv thaiv kev ntsuas yuav tsum tau ua.

Thaum lub sij hawm ua cov txheej txheem Extrusion, nws yog qhov tseem ceeb los xaiv cov kua nplaumant tsim kom tiv thaiv kev tuag. Piv txwv li, cov hau kev xws li lub tsho extrusion thiab iav covreation extrusion tuaj yeem siv. Nws yuav tsum tau sau tseg tias qhov deformation thermal nyhuv ntawm titanium alloys loj thiab cov kev saib xyuas kev saib xyuas tsis zoo, yog li tiv thaiv kev tiv thaiv dhau thaum lub sijhawm excusion deformation.
Forging thiab Casting
Ntawm qhov tod tes, titanium alloys muaj kev nkag siab heev rau kev zam txim cov txheej txheem. Kev hloov pauv ntawm kev tsis txaus siab rau qhov kub, deformation npaum li cas, deformation ceev thiab txias nrawm yuav cuam tshuam rau micrascium alloys. Txhawm rau kom tswj tau zoo dua microstructure thiab cov khoom ntawm kev lom zem, paub ntau yam kev ua kom tau siv dav dav thiab muaj kev kub ntxhov hauv kev ua lag luam titanium ntau nyob rau hauv xyoo tas los no.

Vim yog cov tshuaj lom neeg muaj ntau yam ntawm titanium thiab titanium alloys, lawv muaj feem ntau yog lwm cov neeg nyob hauv huab cua, thiab tseem siv nrog cov khoom siv refractory feem ntau siv hauv cov txheej txheem casting. Yog li no, lub casting ntawm titanium alloys, tshwj xeeb tshaj yog peev txheej, yog ntau nyuaj dua peev Casting ntawm Aluminium thiab Hlau. Nyob rau hauv thaum ntxov hnub ntawm titanium casting, txij li kev txhim kho tshuab Casting, xws li Ti6al4V thiab Ti5Al2.5SN, tau tsuas yog siv raws li casing alloy cov ntaub ntawv. Cov alloys tseem siv dav niaj hnub no. Txawm li cas los xij, nrog kev nce qib ntawm Titanium Casting Technology thiab kev txhim kho ntawm cov kev xav tau ntawm cov txheej txheem, tshwj xeeb tshaj yog cov kev ua kom ruaj khov, tshwj xeeb tshaj plaws ntawm cov txheej txheem ua kom muaj zog, tshwj xeeb tshaj yog cov khoom siv ua pov thawj

Hauv cov ntsiab lus, txawm hais tias titanium alloys tau siv dav hauv ib lub teb thiab lwm thaj teb vim lawv cov nqi ua tau zoo, lawv cov nqi ua haujlwm tseem txwv lawv daim ntawv thov. Nrog rau kev sib tawg ntawm titanium smanium smanium smelting thev naus laus zis thiab kev siv cov peev xwm ntawm titanium hauv kev lag luam pej xeem yuav raug tso tawm ntxiv. Tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm shrbuilding, tsheb tsim, kev lag luam tshuaj, hluav taws xob, kev lag luam ntawm titanium yuav pab txhawb nqa hauv kev loj hlob sai. Nyob rau tib lub sijhawm, qhov no tseem yuav txhawb kev lag luam txuas ntxiv ntawm titanium kev lag luam thiab titanium ua tshuab.

Peb tuaj yeem muab cov khoom lag luam zoo, kev ua haujlwm zoo thiab cov neeg sib tw. Peb tau cog lus los ua cov khoom tooj liab zoo xws li tooj liab cov roj, cov xaim tooj liab, tooj liab, tooj liab pob thiab lwm yam khoom me.
