Titanium Alloy Classification

Titanium yog ib qho allotropic isomer nrog lub melting point ntawm 1720 degree. Nws muaj qhov ntom ntom hexagonal lattice qauv hu ua -titanium thaum nws qis dua 882 degree, thiab nws muaj lub cev-centred cubic lattice qauv hu ua -titanium thaum nws siab tshaj 882 degree. Kev siv cov titanium cov yam ntxwv sib txawv ntawm ob lub qauv saum toj no, ntxiv cov ntsiab lus alloying tsim nyog, kom lub sijhawm hloov pauv kub thiab theem cov ntsiab lus maj mam hloov thiab tau txais cov koom haum sib txawv ntawm titanium alloys (titanium alloys). Nyob rau hauv chav tsev kub, titanium alloys muaj peb hom matrix organisation, titanium alloys kuj muab faib ua peb pawg: -alloys, (+) alloys thiab -alloys. Hauv Suav teb, cov hlau no raug xa mus rau TA, TC thiab TB feem.
Alpha titanium alloy
Nws yog ib-theem-theem alloy muaj li ntawm-theem khoom tov, uas yog-theem, ruaj khov, siab hnav tsis kam tshaj titanium ntshiab, thiab muaj zog oxidation tsis kam, ob qho tib si ntawm qhov kub thiab txias ntawm kev siv tswv yim. Nyob rau hauv qhov kub ntawm 500 degree -600 degree, nws tseem tuav nws lub zog thiab creep tsis kam, tab sis nws tsis tuaj yeem muaj zog los ntawm kev kho cua sov, thiab nws lub zog kub hauv chav tsis siab.
Titanium alloy
Nws yog ib-theem-theem alloy tsim los ntawm-theem cov khoom siv tshuaj, uas muaj lub zog siab yam tsis muaj kev kho cua sov, thiab cov hlau txuas ntxiv muaj zog ntxiv tom qab quenching thiab aging, thiab lub zog ntawm chav tsev kub tuaj yeem ncav cuag 1,372-1 ,666MPa; Txawm li cas los xij, nws muaj qhov tsis zoo thermal stability, thiab nws tsis tsim nyog siv rau qhov kub thiab txias.
+ Titanium alloy
Nws yog ob-theem alloy nrog kev ua tau zoo, kev ruaj ntseg zoo, zoo toughness, plasticity thiab high-temperature deformation zog, tuaj yeem ua tau zoo dua kub siab ua, tuaj yeem quenched, aging kom lub alloy muaj zog. Lub zog tom qab kev kho cua sov yog li 50% mus rau 100% siab dua lub xeev annealed; Lub zog kub kub, tuaj yeem ua haujlwm ntev ntawm qhov kub ntawm 400 degree txog 500 degree, thiab nws cov thermal stability yog thib ob rau titanium alloy.
Feem ntau siv ntawm peb titanium alloys yog -titanium alloy thiab + -titanium alloy; -titanium alloy muaj qhov zoo tshaj plaws machinability, + -titanium alloy yog qhov thib ob zoo tshaj plaws thiab -titanium alloy yog qhov phem tshaj. -titanium alloy yog codenamed TA, -titanium alloy yog codenamed TB thiab + -titanium alloy yog codenamed TC.

Titanium alloys tuaj yeem muab faib ua cov hlau tsis muaj cua sov, cov alloys muaj zog, corrosion-resistant alloys (titanium - molybdenum, titanium - palladium alloys, thiab lwm yam), tsis kub-kub alloys, thiab tshwj xeeb muaj nuj nqi alloys (titanium - hlau hydrogen cia cov ntaub ntawv. thiab titanium - nickel nco alloys) thiab lwm yam. Cov muaj pes tsawg leeg thiab cov khoom ntawm cov alloys raug pom nyob rau hauv lub rooj.
Kev kho cua sov Titanium alloys tuaj yeem tau txais cov txheej txheem sib txawv thiab cov koom haum los ntawm kev kho cov txheej txheem kho cua sov. Nws feem ntau ntseeg tias lub koom haum zoo isometric muaj cov yas zoo dua, thermal stability thiab qaug zog; Lub koom haum zoo li rab koob muaj lub zog muaj zog ntau dua, lub zog nkag thiab tawg toughness; sib xyaw isometric thiab koob zoo li lub koom haum muaj kev ua tau zoo tag nrho.
