Kev txhim kho ntawm aero-engine kev ua tau zoo yog ze rau kev sib koom tes ntawm kev siv tshiabhigh-temperature titanium alloysthiab advanced structural tsim. Txij li thaum xyoo 1990, Tuam Tshoj tau nrawm cov txheej txheem tshawb fawb ntawm cov ntaub ntawv kub kub titanium tshiab thiab tsim cov ntaub ntawv tshiab xws li 550 degree high-temperature titanium, 600 degree high-temperature titanium, burn-resistant titanium alloy, thiab Ti-Al Intermetallic Alloys. .
Nyob rau hauv cov nqe lus ntawm high-temperature titanium alloys, thawj tiam ntawm 550 degree TA12 thiab 600 degree Ti60 muaj tsawg lub ntiaj teb Nd ntawm nws tus kheej tsim nyob rau hauv Tuam Tshoj muaj zoo heev thermal zog zog, Txawm li cas los, vim tsis muaj kev tshawb fawb reserves nyob rau hauv vuam technology thiab cov yooj yim segregation. ntawm lub ntiaj teb tsis tshua muaj theem ntawm cov qoob loo ciam teb hauv cheeb tsam weld, uas yog ib qho yooj yim ua rau nkig tawg ntawm kev sib koom tes, cov teeb meem no tsis tau daws tau zoo thiab tsis tau siv rau hauv aero-engine.
Raws li cov electron concentration txoj kev xav, nyob rau hauv qhov tsim nyog siv 2 theem ntxiv dag zog thiab silicide precipitated theem ntxiv dag zog rau tib lub sij hawm, Nb thiab Ta ntsiab tau ntxiv rau lub Ti-Al-Sn-Zr-Mo-Si alloy system mus ntxiv txhim kho lub cov nyhuv ntawm cov khoom sib xyaw ua ke ntawm cov khoom sib xyaw ua kom muaj zog. Qhov thib ob tiam ntawm 550 degree TA32 thiab 600 degree TA29 thiab TA33 nrog zoo thermal zog, forging, thiab vuam zog tau tsim.TA29 thiab TA33 titanium alloys muaj me ntsis txawv nyob rau hauv muaj pes tsawg leeg, thaum qhov sib txawv nyob rau hauv kev ua tau zoo theem mas nyob ntawm tus txheej txheem tswj yam.
Raws li qhov thib ob tiam ntawm 600 degreehigh-temperature titanium alloy, 650 degree Ti65 tau tsim ntxiv los ntawm kev ntxiv W lub ntsiab lus thiab nce cov ntsiab lus ntawm TA lub caij, kom lub sijhawm ntev kev pabcuam kub ntawm cov tshuaj ntxiv dag zog.high-temperature titanium alloyyuav tsum tau tawg los ntawm cov tsoos 600 degree thermal barrier kub. Nyob rau hauv cov nqe lus ntawm kev tshawb fawb ntawm nplaim retardant titanium alloys, ob lub kub resistant ti-v-cr series nplaim retardant titanium alloys tau tsim, uas yog TB12 nplaim retardant titanium alloy (Ti40) ntev siv ntawm 500 degree thiab tf550 nplaim retardant titanium alloy ntev siv nyob rau hauv. 550 degree. Txoj kev tshawb fawb ntawm cov nplaim hluav taws kub thiab cov khoom siv kho kom zoo ntawm TB12 thiab tf550 titanium alloys qhia tau hais tias ob lub alloys muaj cov nplaim hluav taws zoo sib xws, thiab qhov sib txawv ntawm V cov ntsiab lus feem ntau cuam tshuam rau thermal zog ntawm cov ntaub ntawv. Hauv kev tshawb fawb ntawm Ti-Al intermetallic alloys (2 ntxiv rau O ntxiv rau B2) peb-theem Ti3Al alloy, Ti2AlNb alloy raws li O theem, thiab Kev tshawb fawb ntawm -TiAl alloy qhia tau hais tias qhov kev pabcuam mus sij hawm ntev ntawm Ti-Al intermetallic compound alloy ncav cuag 650 ~ 800 degree.
