Thaum TC11 titanium alloy yog siv los ua cov khoom tseem ceeb xws li aircraft engine compressor discs, hniav, thiab brakes, nws yuav tsum muaj qhov zoo ntawm chav tsev kub, lub zog kub, thiab muaj zog toughness. Cov qauv ntawm TC11 titanium alloy tuaj yeem tswj tau los ntawm kev kho cua sov, kom nws tuaj yeem tau txais cov khoom zoo heev.
Tam sim no, qhov kev kho cua sov tshaj plaws rau TC11 titanium alloy yog (950 -970) degree / 120 min / AC +530 degree / 360 min / AC. Txawm li cas los xij, rau qhov loj-loj TC11 titanium alloy rods nrog ib txoj kab uas hla ntawm ntau tshaj 200 hli, thaum lub sij hawm kho cua sov txheej txheem, qhov qis kub poob hauv cov tub ntxhais feem ntau ua rau muaj qhov sib txawv ntawm cov qauv thiab cov khoom siv kho tshuab ntawm ntau qhov chaw.
Tsis tas li ntawd, TC11 titanium alloy muaj cov qib siab ntawm alloying thiab muaj cov khoom sib cais yooj yim Mo. Yog li ntawd, cov qauv hlau yog rhiab heev rau cov txheej txheem tsis ua haujlwm, thiab nws nyuaj rau kev tswj xyuas qhov sib xws ntawm cov qauv. Yog li ntawd, cov qauv kev faib tawm ntawm microstructure thiab txhua yam khoom ntawm qhov loj-loj TC11 titanium alloy rods tom qab kev kho cua sov tau kawm txhawm rau muab cov ntaub ntawv siv rau kev tswj xyuas qhov sib xws ntawm microstructure thiab txhua yam khoom hauv cov txheej txheem tsim khoom.
(1) Tom qab kev kho cua sov ntawm 970 degree / 120 min / AC +530 degree / 360 min / AC, muaj qee qhov sib txawv hauv microstructure ntawm cov haujlwm sib txawv ntawm qhov loj-loj TC11 titanium alloy rods. Ntawm lawv, cov qauv kev hloov pauv ntawm D / 2 yog qhov pom tseeb tshaj plaws, feem ntau tshwm sim raws li kev nce qib hauv cov ntsiab lus, kev loj hlob ntawm cov nplej, thiab txo qis hauv cov ntsiab lus theem.
(2) Cov kev hloov hauv chav tsev kub tensile zog ntawm qhov chaw sib txawv ntawm qhov loj-loj TC11 titanium alloy rods yog ze ze rau lub microstructure. Raws li qhov ntev kev taw qhia, qhov sib txawv microstructure ntawm D / 2 yog qhov pom tseeb tshaj plaws. Chav tsev kub tensile zog qhia tau hais tias lub zog tensile maj mam txo los ntawm ntug mus rau qhov chaw thiab cov plasticity nce.
(3) Lub microstructure ntawm qhov loj-loj TC11 titanium alloy rods muaj qhov cuam tshuam loj rau nws qhov kub thiab txias tensile zog thiab cuam tshuam toughness. Qhov ze rau qhov chaw (D / 2 thiab L / 2), qhov qis dua qhov kub siab tensile lub zog thiab cuam tshuam toughness, tab sis qhov kub-kub yas hloov tsis pom tseeb.
