Txheej txheem cej luam Ntawm Titanium Alloy Lub cev muaj zog

Titanium yog ib qho allotropic isomer nrog lub melting point ntawm 1668 degree. Nws muaj qhov ntom ntom hexagonal lattice qauv hauv qab 882 degree. Nws muaj cov txheej txheem hexagonal lattice, hu ua -titanium, qis dua 882 degree. Saum toj no 882 degree, nws muaj lub cev-centered cubic lattice qauv, hu ua -titanium. Siv cov yam ntxwv sib txawv ntawm ob qho tib si saum toj no ntawm titanium, los ntawm kev ntxiv cov ntsiab lus alloying tsim nyog, maj mam hloov cov theem hloov kub thiab cov ntsiab lus theem, kom tau txais cov txheej txheem sib txawv ntawm titanium alloys. Nyob rau hauv chav tsev kub, titanium alloys muaj peb hom matrix lub koom haum, thiab titanium alloys tau muab faib ua peb hom hauv qab no: -alloys, (+) alloys thiab -alloys. Tuam Tshoj yog sawv cev los ntawm TA, TC thiab TB feem.

Alpha Titanium Alloy

Nws yog ib-theem-theem alloy muaj li ntawm alpha-phase khoom tov. Nws yog alpha theem nyob rau hauv chav tsev kub los yog siab dua cov ntaub ntawv thov kub. Nws muaj qhov ruaj khov, muaj kev hnav siab dua li cov ntshiab titanium, thiab muaj zog oxidation tsis kam. Nyob rau hauv 500 degree ~ 600 degree kub tseem tuaj yeem tswj lub zog thiab nkag siab, tab sis kev kho cua sov tsis tau ntxiv dag zog, chav sov lub zog tsis siab.

Titanium alloy

Nws yog ib-theem-theem alloy tsim los ntawm-phase khoom tov.

Nws muaj lub zog siab yam tsis muaj kev kho cua sov. Tom qab quenching thiab aging kev kho mob, lub alloy yog ntxiv dag zog. Lub zog ntawm chav tsev kub tuaj yeem ncav cuag 1372 ~ 1666 MPa, tab sis lub thermal stability tsis zoo, thiab nws tsis haum rau kev siv ntawm 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. Nws tuaj yeem ua tau zoo los ntawm kev kub siab thiab cov hlau tuaj yeem ntxiv dag zog los ntawm quenching thiab aging. Lub zog tom qab kev kho cua sov yog li 50% mus rau 100% siab dua li ntawm lub xeev annealed; Lub zog kub kub yog siab, thiab nws tuaj yeem ua haujlwm ntev ntawm qhov kub ntawm 400 degree txog 500 degree, thiab thermal stability yog thib ob ntawm titanium alloy.
