Kab lus no tsom mus rau cov khoom nkag thiab cov thermal expansion zog ntawm Qib 7 titanium alloy. Los ntawm cov ncauj lus kom ntxaws cov ntaub ntawv sim thiab ntsuas ntsuas, nws lub hom phiaj los muab kev txhawb zog rau kev tshawb fawb thiab kev siv engineering hauv cov haujlwm muaj feem xyuam.
1. Txheej txheem cej luam ntawm cov yam ntxwv ntawm qib 7 titanium alloy
Qib 7 titanium alloy (Ti-0.2Pd) yog ib tug neeg sawv cev ntawm - titanium alloy. Qhov sib ntxiv ntawm txhuas nyob rau hauv nws muaj pes tsawg leeg ho txhim khu lub zog thiab oxidation tsis kam ntawm cov hlau, thaum ntxiv ntawm vanadium ntxiv txhim kho cov yas thiab thermal stability. . Cov yam ntxwv no ua rau Qib 7 titanium alloy ua tau zoo nyob rau hauv kev xav tau ib puag ncig, sib txuas cov zog tshwj xeeb, zoo heev corrosion kuj thiab zoo biocompatibility.
2. In-depth tsom xam ntawm creep kev ua tau zoo
Creep, raws li cov yas deformation mus tas li ntawm cov ntaub ntawv uas tshwm sim dhau sijhawm nyob rau hauv qhov kub thiab txias tsis tu ncua, yog qhov tseem ceeb rau kev siv qib 7 titanium alloy nyob rau hauv high-temperature ib puag ncig xws li aerospace thiab aerospace. Qhov kev sim tau nthuav tawm qhov cuam tshuam ntawm qhov kub thiab txias, kev ntxhov siab thiab lub sijhawm ntawm cov khoom nkag ntawm qib 7 titanium alloy los ntawm kev ntsuas kub siab tensile. Kev tshawb fawb qhia tau hais tias thaum kub nce thiab kev ntxhov siab nce, qhov nkag mus nrawm nrawm, thiab cov txheej txheem nkag tuaj yeem muab faib ua peb theem: pib, khov kho thiab nrawm. Los ntawm kev kho cov nplej, ntxiv cov ntsiab lus alloy tshwj xeeb thiab ua kom zoo rau cov txheej txheem kho cua sov, kev nkag siab ntawm qib 7 titanium alloy tuaj yeem txhim kho tau zoo.
3. Kev txhais lus ntawm thermal expansion kev ua tau zoo
Thermal expansion yog ib qho phenomenon uas lub ntim los yog ntev ntawm cov khoom hloov thaum kub hloov. Nws cov coefficient yog qhov taw qhia tseem ceeb ntawm thermal stability ntawm cov khoom. Lub high-precision thermal dilatometer tau siv los ntsuas Qib 7 titanium alloy, thiab nws tau pom tias nws cov kab nthuav dav coefficient nce nrog kub thiab cuam tshuam loj heev los ntawm microstructure thiab alloy muaj pes tsawg leeg. Los ntawm kev kho cov alloy muaj pes tsawg leeg thiab optimizing lub microstructure, xws li grain refinement, thermal expansion cwj pwm ntawm Qib 7 titanium alloy yuav tau zoo tswj kom haum raws li cov kev cai nyob rau hauv txawv kub tej yam kev mob.
4. Kev ua tau zoo ntawm kev ua haujlwm thiab kev cia siab rau kev thov
Kev tsom xam tag nrho ntawm cov creep thiab thermal expansion zog ntawm Qib 7 titanium alloy qhia tau hais tias nws tshwj xeeb zoo nyob rau hauv lub tshav pob ntawm high-temperature cov ntaub ntawv. Nyob rau hauv lub neej yav tom ntej, txhawm rau txhim kho nws cov kev ua tau zoo, kev sib raug zoo ntawm microstructure thiab macroscopic zog yuav tsum tau kawm nyob rau hauv qhov tob, thiab ntau sophisticated alloy tsim thiab kev kho cua sov txheej txheem yuav tsum tau tshawb nrhiav. Nyob rau tib lub sijhawm, nrog kev xav tau ntau ntxiv rau cov ntaub ntawv ua tau zoo hauv aerospace, tshuaj lom neeg kev lag luam, marine engineering thiab lwm yam kev lag luam, daim ntawv thov kev cia siab ntawm Qib 7 titanium alloy yuav dav dua.
Nyob rau hauv luv luv, Qib 7 titanium alloy qhia tau hais tias muaj zog kev sib tw nyob rau hauv ntau engineering teb nrog nws zoo heev creep zog thiab nruab nrab thermal expansion zog. Los ntawm kev ua tau zoo tas mus li kev ua tau zoo thiab thev naus laus zis tshiab, Qib 7 titanium alloy yuav muaj tseeb txhaj tshuaj tshiab rau hauv txoj kev loj hlob ntawm kev lag luam.
