Kev Tsim Kho Thiab Kev Siv Hauv Tsev Kho Mob Titanium Alloys Thiab Tshiab Titanium Alloy Cov Khoom

Vim txoj kev loj hlob ntawm aerospace technology, kev tshawb fawb thiab kev loj hlob ntawm titanium alloys tau muaj zog heev txheeb ze rau titanium daim txhuam cev. Kev kawm tau zoo tau ua los ntawm kev tshawb fawb yooj yim mus rau kev tshawb fawb txog cov cuab yeej cuab tam rau kev tshawb fawb siv. Kev tshawb fawb ntawm interstitial atoms cuam tshuam rau lub zog thiab bulk modulus ntawm titanium, kev tshawb fawb tseem ceeb. Kev vam meej tau ua tiav nyob rau hauv cov ntsiab lus simulation kev tshawb fawb ntawm tus cwj pwm interfacial ntawm cov khoom sib xyaw, kom ntxiv dag zog rau cov hlau, thiab kev tshawb fawb ntawm atom-vacancy kev sib cuam tshuam hauv alloys.

Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv titanium rau cov ntawv thov hauv ntau qhov chaw, tseem muaj ntau chav rau kev tsim ua haujlwm ntawm cov ntaub ntawv alloy los ua lub luag haujlwm tseem ceeb. Siv rau aerospace teb ntawm BT37 alloy, NIN CT20 alloy, NIN Ti-600 alloy, Ti-60 alloy, IT15D alloy, NIN Ti-40 alloy, NIN Ti-26 alloy , NIN TP-650 alloy muaj peev xwm ua tau raws li xyoo tas los no, qhov sib txawv ntawm cov ntaub ntawv ntawm kev siv cov kev xav tau ntawm kev tshawb fawb hauv tsev thiab txawv teb chaws ntawm cov qib tshiab ntawm cov ntaub ntawv alloy yog tus sawv cev. Qee qhov tseem tuaj yeem txo tus nqi thiab qhov zoo, qhov kub thiab txias titanium alloys (xws li Ti53311S) kev tshawb fawb kuj tseem yog qhov hotspot) siv nyob rau hauv kev lag luam shipbuilding Timetal511 alloy NIN TiB19 alloy thiab NIN Ti-91 alloy rau Ti{{ 13}}ZrlONb alloy thiab Ti-29Nb-13Ta-4.6Zr, xws li cov nkoj loj nyob rau hauv cov nqe lus ntawm toughness, corrosion kuj thiab acoustic transmittance, thiab lwm yam. Muaj ib qho tseem ceeb Kev txhim kho Tsinghua University nyob rau xyoo tas los no los tsim cov khoom siv pob txha yog ib tus neeg sawv cev ntawm daim ntawv thov hauv kev ua liaj ua teb lom neeg, dav siv hauv pej xeem kev sib tw ntawm cov koom haum golf siv cov titanium alloy hu ua KSTil9, yog cov tuam txhab tsim khoom nquag txhawb cov khoom siv titanium alloy. Txoj kev loj hlob ntawm aircraft carriers thiab kev loj hlob ntawm marine kev lag luam. zrNbTaPd thiab Sn feem ntau yog siv los ua titanium alloy cov ntsiab lus los txhim kho cov khoom siv kho tshuab thiab biocompatibility, yog li txo cov nqi thiab txhim kho zoo.

Kev tshawb fawb ntawm daim ntawv thov ntawm titanium rods thiab alloys hauv kev tsim kho, tsheb, marine engineering, kev kho mob thiab kev ua kis las yog pib nce. Nyob rau hauv xyoo tas los no, titanium tau nyiam heev vim nws muaj koob meej, tshwj xeeb tshaj yog nyob rau hauv lub tshav pob ntawm desalination. Kev kho mob titanium alloy 1C 20Ti 6A17Nb cov khoom tau raug siv hauv kev kho mob.
