BLT-Ti65, ntau yam khoom nyob ze-alpha high-temperature titanium alloy, sawv tawm rau nws lub peev xwm zoo tshaj plaws los tuav lub zog tshwj xeeb, ductility, creep resistance, corrosion resistance, thiab thermal stability ntawm kub txog 650 degree. Qhov no deb tshaj qhov kev txwv kub ntawm cov tsoos kub-kub titanium alloys, ua rau nws yog ib tug heev nrhiav-tom qab cov ntaub ntawv nyob rau hauv aerospace, chemical khoom, marine engineering, thiab lwm yam kev ua tau zoo daim ntawv thov.
Txawm li cas los xij, cov txheej txheem tsim khoom ntxiv ntawm Ti65 hmoov feem ntau ntsib cov teeb meem xws li porosity thiab tawg, tshwm sim los ntawm unfused, ib nrab melted hmoov hais, thiab interlayer / khiav delamination. Cov teeb meem no, ua raws li kev ntxhov siab concentrators, ua rau muaj kev pheej hmoo ntawm cov khoom siv tsis ua haujlwm, uas ua rau muaj kev puas tsuaj thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom tsim. Txhawm rau hais txog qhov teeb meem no, cov hmoov tshawb fawb thiab kev tsim kho engineers ntawm Bolytech tau tsis tu ncua nrhiav kev nce qib hauv kev siv tshuab, qhia txog BLT-Ti65 hmoov tshwj xeeb rau kev xaiv Laser Melting (SLM) thiab Directed Energy Deposition (DED).
Cov tshuaj nominal muaj pes tsawg leeg ntawm BLT-Ti65 hmoov yog Ti-5.9Al-4Sn-3.5Zr-0.3Mo-0.4Si-0 .3Nb-2. 15-53μm (tsim rau cov txheej txheem SLM) thiab 75-180μm (tsim rau cov txheej txheem DED). Tom qab kev kho cua sov, cov khoom tsim los ntawm kev siv 15-53μm BLT-Ti65 hmoov nthuav tawm cov khoom muaj zog ntawm 483-503Mpa, tensile zog ntawm 604-624Mpa, thiab elongation tus nqi ntawm 16.5%-26. 5% ntawm 650 degree. Ib yam li ntawd, cov khoom ua nrog 75-180μm hmoov ua kom pom qhov ua tau zoo ntawm 478-538Mpa, tensile lub zog ntawm 588-648Mpa, thiab elongation tus nqi ntawm 22% -32% nyob rau hauv tib qhov kub thiab txias . Bolytech tau showcased nws txoj kev sib haum xeeb los ntawm kev ua tiav cov txee ntom ntom-Ti66} μm BLT-Ti66} μm BLT-Ti66} μm BLT kev ua kom sib xyaw Carin tis tsim.
Bolytech tau kov yeej cov teeb meem tseem ceeb uas cuam tshuam txog kev tawg, kev tswj kev deformation, thiab kev tswj cov txheej txheem luam ntawv hauv BLT-Ti65, tsim cov txheej txheem tsim tau thiab cov kev txwv uas tam sim no sib xws nrog tag nrho Bolytech cov qauv khoom siv.
Tuam Tshoj txoj kev tshawb fawb rau hauv high-temperature titanium alloys, tshwj xeeb tshaj yog cov haum rau additive manufacturing, tseem nyob rau hauv nws cov me nyuam mos. Los ntawm kev ua kom zoo dua ntawm Ti65 qhov muaj pes tsawg leeg, tsim cov txheej txheem tsis, thiab kev tswj cov txheej txheem, Bolytech tau ua tiav thiab siv tau BLT-Ti65, qhib qhov muaj peev xwm tshiab rau daim ntawv thov kub-kub titanium alloys hauv high-temperature Cheebtsam ntawm aero-engines, kev sim kev tshawb fawb. koom nrog cov ntaub ntawv tshiab thiab cov qauv, thiab lwm yam.
