Gr12 titanium alloy yog cov hlau uas muaj titanium ua cov khoom siv hauv paus thiab lwm yam khoom, nrog rau qhov zoo ntawm qhov tsis tshua muaj siab, muaj zog tshwj xeeb, zoo corrosion kuj, zoo kub thiab kub tsis kam, tsis muaj hlau nplaum, zoo cuam tshuam, vuam zoo. kev ua tau zoo, thiab lwm yam, uas yog siv dav hauv kev lag luam tshuaj lom neeg, aerospace, hluav taws xob fais fab, kev ua kis las thiab kev ua si, kev xa khoom, marine engineering, tshuaj thiab metallurgy. Nyob rau hauv lub tshav pob ntawm nkoj thiab dej hiav txwv engineering, raws li lub Cheebtsam los tiv thaiv kev ntsuam xyuas ntawm loj marine ib puag ncig, nws zus tau tej cov hull Cheebtsam ntawm cov khoom yuav tsum muaj zoo corrosion kuj, tshav kub tsis kam thiab kub tsis kam thiab cuam tshuam tsis kam, thaum nws vuam kev kawm yuav tsum. ua tau zoo, thiab titanium alloy cov ntaub ntawv nyob rau hauv qhov zoo saum toj no tib lub sij hawm, nws qhov ntom yog me me, dua li lub zog ntawm cov yam ntxwv ntawm lub zog, tab sis kuj zoo heev txhim khu kev ua haujlwm ntawm cov khoom siv.
Daim ntawv thov ntawm titanium alloy nyob rau hauv nkoj tau txhim kho lub neej kev pab cuam ntawm ships nyob rau hauv lub marine ib puag ncig thiab kev ua tau zoo ntawm cov khoom. Yog li ntawd, titanium thiab titanium alloys yog hu ua "hlau yav tom ntej", "thib peb hlau", "marine hlau" thiab hais txog. Vim muaj kev ua tau zoo ntawm titanium alloy thiab nws daim ntawv thov tseem ceeb hauv kev ua haujlwm ntawm marine engineering thiab tub rog, Russia, Tebchaws Meskas, Tuam Tshoj, Fabkis, Nyiv thiab lwm lub tebchaws tau txuas nrog qhov tseem ceeb rau kev tshawb fawb thiab kev tsim cov titanium alloy.
Ua ntej, kev tshawb fawb kev nce qib ntawm titanium alloy rau naval nkoj
Kev tshawb fawb ntawm titanium alloy rau cov nkoj yog feem ntau yog nyob rau hauv Russia, Tebchaws Asmeskas, Tuam Tshoj thiab lwm lub tebchaws, tom qab ntau xyoo ntawm kev tshawb fawb thiab kev loj hlob, tau tsim cov txheej txheem ntawm titanium alloy rau cov nkoj kom tau raws li cov kev xav tau ntawm kev loj hlob ntawm lawv lub teb chaws thiab yam ntxwv.
1. Russia
Russia yog lub tebchaws ntxov tshaj plaws hauv ntiaj teb los pib tshawb fawb titanium alloy rau cov nkoj, thiab muaj kev ua haujlwm ntev hauv titanium alloy. Tom qab xyoo ntawm kev sib sau, Russia tau tsim 490MPa, 585MPa, 686MPa, 785MPa thiab lwm yam zog qib ntawm marine titanium alloys, xws li titanium (Ti) -0.3 molybdenum (Mo) -0.8 nickel ( Ni), Ti-3 aluminium (Al) -2.5 vanadium (V), Ti-6Al-2 niobium (Nb) -1 tantalum (Ta) -0.8Mo thiab lwm yam. Cov qib Lavxias tseem ceeb ntawm marine titanium alloys yog PT-3V, 40, 17, PT-7M, PT-1M, 3M, 5V, TL-3, TL{ {25}}, PT-7MW thiab lwm yam. Ntau pawg ntawm titanium alloys muaj ntau hom kev siv, xws li PT-3V yog siv rau vuam, thaum PT-7M feem ntau yog siv rau cov kav dej. Xyoo ntawm R & D xyaum tau ua rau Russia ua tus thawj coj thoob ntiaj teb hauv kev tshawb fawb thiab kev siv titanium alloys rau nkoj.
Russia lub marine titanium alloy system yog tsim raws li kev siv titanium alloys ntawm cov nkoj, feem ntau muab faib ua titanium alloys rau hulls, titanium alloys rau nkoj machinery, titanium alloys rau nkoj fais fab engineering, thiab hais txog. Raws li tau hais los saum no, PT-1M belongs rau titanium alloy rau lub nkoj, 3M belongs rau titanium alloy rau nkoj machinery, thiab titanium alloy 40 belongs rau titanium alloy rau nkoj fais fab engineering. Txawm li cas los xij, muaj qee qhov teeb meem nrog cov txheej txheem kev faib tawm no, titanium alloy tuaj yeem siv rau cov khoom raws li ntau yam kev faib tawm, thiab muaj cov ntawv sib tw.
2. Tebchaws Meskas
US nkoj nrog titanium alloy yog nyob rau hauv aerospace titanium alloy nyob rau hauv lub hauv paus ntawm thaum pib ntawm lub xyoo 1950, lub US Navy pib paub tias titanium thiab titanium alloy cov ntaub ntawv siv tau nyob rau hauv ships, thiab pib sim mus kawm thiab xaiv titanium alloys. haum rau thaj chaw marine. Xyoo 1963, US titanium thiab titanium alloy cov ntaub ntawv siv hauv nkoj los ua cov kev tshawb fawb loj thiab kev loj hlob thiab ua tiav kev vam meej, xws li US "Alvin" sib sib zog nqus submersible plhaub npaj rau kev siv cov khoom siv titanium alloy kom nce qhov tob ntawm kev dhia dej los ntawm thawj 1868m rau 3658m. "Alvin" sib sib zog nqus submarine plhaub npaj ntawm kev siv titanium alloy cov ntaub ntawv, qhov tob tob ntawm qhov qub 1868m mus rau 3658m.
Tam sim no, Tebchaws Asmeskas, daim ntawv thov tseem ceeb ntawm titanium alloys suav nrog cov ntshiab titanium, Ti-3Al-2.5V, Ti-6Al-4V, Ti{{5 }}Al-4VELI,
Ti-5Al-1Zr-1Sn-1V-0.8Mo-0.1Si, Ti-6Al{{9 }}Nb-1Ta-0.8Mo, Ti-3Al-8V-6Cr-4Zr-4Mo thiab li ntawd ntawm. Tebchaws Asmeskas yuav tau siv ntau cov titanium alloys raws li qib ASTMB265, suav nrog Gr.1, Gr.2, Gr.3, Gr.5, Gr.9, Gr.12, Gr.20, Gr.32. Gr.1, Gr.2, Gr.3 muaj pes tsawg leeg ntawm industrially ntshiab titanium qib 1, 2, thiab 3, Gr.5 muaj pes tsawg leeg ntawm Ti-6Al-4V, Gr.9 muaj pes tsawg leeg ntawm Ti{ {37}}Al -2.5V, Gr.12 muaj pes tsawg leeg yog Ti-0.3Mo-0.8Ni, Gr.20 muaj pes tsawg leeg yog Ti-3Al{{47} }V-6Cr-4Zr-4Mo, Gr.32 muaj pes tsawg leeg yog Ti-5Al-1Zr-1Sn-1 V-0.8Mo-0.1Si. Cov qib sib txawv ntawm titanium thiab titanium alloys muaj cov khoom sib txawv. Ntshiab titanium yog pheej yig dua los npaj, tab sis tsis muaj zog li titanium alloys. Titanium alloys feem ntau yog siv rau hauv kev npaj cov nkoj 'cov khoom siv, fasteners, pipelines, twj, li qub, thiab lwm yam. Ti-5Al-1Zr-1Sn-1V{ {64}}.8Mo-0.1Si muaj cov pob txha zoo toughness thiab tsis kam rau kev nyuaj siab corrosion, thiab nws cov weldability, cuam tshuam tsis kam thiab lwm yam khoom zoo dua li lwm cov qib ntawm titanium alloys, thiab feem ntau siv rau hauv kev npaj. ntawm structural qhov chaw thiab fasteners.
3. Suav teb
Nyob rau xyoo 1960, Tuam Tshoj pib tsim cov titanium alloy rau kev siv dej hiav txwv. Tom qab ntau xyoo ntawm txoj kev loj hlob, Tuam Tshoj titanium alloy R & D thiab daim ntawv thov qib tau zoo heev, tuaj yeem ua tau raws li kev tsim kho ntawm cov nkoj hauv ntau qhov sib txawv thiab qib sib txawv ntawm cov kev xav tau ntawm cov khoom loj ntawm cov phaj, phaj, forgings, raj, hlau, nplhaib. castings thiab lwm yam khoom sib txawv. Tuam Tshoj tau koom nrog kev tshawb fawb ywj pheej thiab kev tsim kho ntawm titanium alloy rau cov nkoj nrog cov koom haum sawv cev yog Northwest Nonferrous Metals Research Institute, Shanghai Iron thiab Steel Research Institute thiab Baoji Titanium Industry Co. Northwest Research Institute of Nonferrous Metals R & D cov txiaj ntsig yog Ti- Boron (B) 19, alloy muaj pes tsawg leeg ntawm Ti-V-Chromium (Cr) - Mo - Zirconium (Zr) - Al; Ti75 alloy, muaj pes tsawg leeg ntawm Ti-3Al-2Mo-2Zr; Ti91 alloy, muaj pes tsawg leeg ntawm Ti-Al-hlau (Fe). Lub koom haum tshawb fawb Shanghai Hlau thiab hlau yog sawv cev los ntawm Ti80, nrog rau cov muaj pes tsawg leeg
Ti{{0}}.0Al-2.5Nb-2.2Zr-1.2Mo, yield zog ntawm 900MPa, yog ze li ntawm-type high-strength titanium alloy, corrosion tsis kam. Baoji Titanium Industry Co., Ltd. muaj ib tug neeg sawv cev titanium alloy rau Ti631, nws muaj pes tsawg leeg yog Ti-6Al-3Nb-1Mo, yog 785MPa qib titanium alloy rau nkoj.
Tam sim no, Tuam Tshoj tau tsim ib tug marine titanium alloy system nrog lub teb chaws yam ntxwv, ib tug ntau yam ntawm yield zog, lub siab tshaj plaws yield zog ntawm 1150 MPa. Nyob rau hauv Tuam Tshoj lub marine titanium alloy system, raws li lub zog tawm los ntawm cov alloy yog muab faib ua low-strength titanium alloy, nruab nrab-lub zog titanium alloy kub thiab high-strength titanium alloy.
