Ua hauj lwm tej yam kev mob thiab muaj pes tsawg leeg ntawm kub kub 3al{1}}.5v titanium alloy

Daim ntawv qhia txog kev ua haujlwm thiab muaj pes tsawg leeg ntawm qhov kub thiab txias 3al-2.5v titanium alloy! Kub kub titanium alloys yog tsuas yog siv nyob rau hauv lub tsim ntawm aero-engine compressor Cheebtsam, xws li disks, hniav, cov lus qhia, spacers, noj cov ntawv xov xwm thiab lwm yam, uas yuav tsum tau cov khoom kom muaj ib tug tshwj xeeb lub zog, high-temperature creep resistance, qaug zog. lub zog, endurance lub zog thiab lub koom haum stability nyob rau hauv high-temperature ua hauj lwm tej yam kev mob (300 rau 600 degree).
Nrog rau kev txhim kho ntawm kev sib tw-rau-hnyav piv ntawm lub tshuab aero, qhov kub siab siab qhov hluav taws xob qhov hluav taws xob nce siab ua rau kub kub titanium alloy hniav thiab disks nrog kev ua haujlwm kub. Tom qab ntau xyoo ntawm txoj kev loj hlob, qhov siab tshaj plaws ua hauj lwm kub ntawm cov khoom siv ntxiv dag zog rau qhov kub thiab txias titanium alloys tau nce los ntawm 350 degree mus rau 600 degree.

Tebchaws Asmeskas thaum ntxov xyoo 1950 tau ua tiav lub ntiaj teb thawj titanium alloy Ti-64 (Ti-6Al-4}V), siv qhov kub ntawm 300 ~ 350 degree, ua raws li cov kev txhim kho txuas ntxiv ntawm kev siv qhov kub txog li 400 degree lossis yog li IMI-550, BT31 thiab lwm yam alloys;

Kev siv kub siab tshaj 450 degree IMI-679, IMI-685, Ti-6246, Ti-6242 (Ti-6Al-2Sn{{ 7}}Zr-2Mo) thiab lwm yam alloys; kev siv kub txog li 550 ~ 600 degree IMI-829, IMI-834, Ti-6242S, Ti-1100, BT18Y, BT36 thiab lwm yam alloys. Ntawm lawv, feem ntau siv yog Ti-64 thiab Ti-6242 ob titanium alloy qib cov ntaub ntawv.

Tag nrho cov titanium alloys tshiab tsim nyob rau hauv Suav teb ncav cuag ntau tshaj 70 hom tshiab titanium alloys, thiab 600 degree high-temperature titanium alloys nyob rau hauv kev loj hlob mas suav nrog Ti-60, Ti-600 thiab lwm yam alloys, tab sis qhov Performance indexes ntawm kev siv mus sij hawm ntev nyob rau hauv ib puag ncig ntawm 600 degree tseem yuav raug txheeb xyuas.
