TA18 titanium alloy raj Ti-3Al-2.5V titanium alloy raj

TA18 titanium alloy muaj pes tsawg leeg rau Ti-3Al-2.5V, los ntawm TC4 (Ti-6Al-4V) titanium alloy evolved los ntawm ze-alpha-type titanium alloy TA18 titanium alloy muaj qhov zoo ntawm chav tsev kub, kub kub thiab corrosion kuj, tab sis kuj muaj zoo heev kub thiab txias machining txheej txheem plasticity, molding, vuam kev ua tau zoo thiab corrosion kuj. Nws kuj muaj zoo heev plasticity, formability, weldability thiab corrosion kuj nyob rau hauv kub thiab txias ua hauj lwm txheej txheem. Nyob rau hauv chav tsev kub thiab kub nws lub zog yog 20% ​​-50% siab tshaj titanium ntshiab, vuam kev ua tau zoo thiab txias forming kev ua tau zoo dua TC4 alloy.

TA18 alloy feem ntau yog siv nyob rau hauv lub xeev annealed, tab sis kuj nyob rau hauv lub txias ua hauj lwm thiab de-stressed annealed xeev, kuj yuav siv tau nyob rau hauv lub tsim ntawm ua hauj lwm kub txog li 315 degree, thiab ib tug tej yam degree ntawm lub zog thiab oxidation kuj yuav tsum tau ntawm lub Cheebtsam, xws li TA18 titanium alloy seamless raj nyob rau hauv lub aerospace kev lag luam yog tsim rau siv nyob rau hauv aircraft thiab cav high-pressure-resistant, lub teeb yuag hydraulic thiab roj thiab lwm yam piping systems.

TA18 titanium alloy tube nto tiav txheej txheem: TA18 nyob rau hauv cov txheej txheem electrolytic-magnetic composite sib tsoo, vim hnav-pab passivation thiab passivation-pab coj ntawm cov nyhuv synergistic, yog li nyob rau hauv cov txheej txheem tsim nyog, nws nto burrs, khawb thiab lwm yam tsis xws luag tuaj yeem. raug tshem tawm zoo, yog qhov tsim nyog rau kev txhim kho ntawm nws qhov chaw micro-morphology, kom tau txais qhov zoo ntawm qhov zoo. Thaum cov khoom sib nqus sib nqus nrog qhov loj me ntawm 185 μm tau siv los zom rau sab hauv ntawm TA18 hlab rau 50 min ntawm qhov hluav taws xob electrolytic ntawm 9 V, qhov sib tsoo zoo tshaj plaws, qhov chaw ntawm lub workpiece. yog ib yam nkaus thiab tiaj tus, thiab qhov chaw roughness Ra raug txo los ntawm thawj 1.60 μm rau 0.13 μm.

Txias dov txheej txheem ntawm TA18 titanium alloy: (1) Nrog rau kev loj hlob ntawm cov khoom noj, lub radial tensile strain thiab ncig compressive strain nyob rau hauv qhov chaw qhib yuav nce, thiab cov forming load yuav nce, uas yuav txo tau ntawm pwm lub neej. Thaum lub sij hawm pub mis ntau dhau lawm, nws tseem yuav ua rau cov hlau dhau ntawm cov yob seam, ua rau tawg lossis folding. (2) Dov ceev nce, radial tensile strain thiab circumferential compressive strain raug txo, lub ntsug tivthaiv quab yuam kuj txo. (3) Kev sib txhuam coefficient nce, qhov radial tensile strain thiab annular compressive strain nyob rau hauv qhov qhib qhov chaw txo, thiab kev tsim load nce. Rau cov phab ntsa tuab uas ua rau cov teeb meem sab hauv zoo, nws raug pom zoo kom muaj kev sib txhuam kom zoo.
