TC4 / GR5 titanium ntawv

TC4 titanium alloy lub ntsiab Cheebtsam yog titanium, txhuas, vanadium, 6% txhuas thiab 4% vanadium thiab tsis ntau tshaj 3% ntawm lwm yam ntsiab.TC4 titanium alloy yog tam sim no feem ntau lug siv ntau lawm ntawm qhov loj tshaj + - hom alloy. , muaj kev ua tau zoo tag nrho ib puag ncig, kev ruaj ntseg zoo, zoo toughness, plasticity thiab high-temperature deformation zog, tuaj yeem ua kom zoo dua kub siab machining, quenching, aging kom lub alloy muaj zog. Lub zog tom qab kev kho cua sov yog li 50% ~ 100% siab dua lub xeev annealed; Lub zog kub kub, tuaj yeem ua haujlwm ntev ntawm qhov kub ntawm 400 degree ≈ 500 degree, thiab nws cov thermal stability yog thib ob rau titanium alloy.

Titanium alloy phaj siv cov qauv: GB / T 3621-2007, ASTM B265. TC4 titanium alloy phaj thiab titanium thaiv yog cov khoom siv tshuaj lom neeg tseem ceeb thiab cov khoom siv dav hlau, dav siv hauv cov khoom siv tshuaj, roj av, marine, aerospace, tshuaj thiab lwm yam kev lag luam. Nrog rau kev txhim kho kev lag luam thiab thev naus laus zis, ntau thiab ntau thaj chaw tau siv titanium phaj.

TC4 titanium alloy forging txheej txheem.

(1) Thaum lub deformation kub ntawm 1000 degree thiab deformation npaum li cas ntawm 50%, ib tug deformation tus nqi ntawm tsawg tshaj li los yog ntau tshaj 2mm / s yuav pab txo tau qhov kev puas tsuaj ntawm forgings thiab txhim kho qhov zoo ntawm forgings.

(2) Qhov zoo ntawm forgings yog zoo thaum lub deformation kub yog 925 degree, deformation tus nqi yog 1000mm / s thiab deformation tus nqi yog 70%.

(3) Kev cuam tshuam ntawm txhua qhov txheej txheem forging ntawm qhov kev puas tsuaj ntau tshaj plaws ntawm TC4 titanium alloy forgings thaum forging deformation yog raws li hauv qab no: deformation tus nqi> deformation tus nqi> deformation kub.

Titanium phaj manufacturing txheej txheem:

1. Titanium ingots yog forged slabs saum cov hlau recrystallization kub.

2. Rolling ntawm titanium slabs saum lub recrystallization kub.

3. Rolling ntawm titanium slabs txias dov ntawm lub yas deformation kub hauv qab qhov kub thiab txias.

4. titanium phaj maj mam rhuab mus rau qhov kub thiab txias, khaws cia rau lub sijhawm txaus, thiab tom qab ntawd txias ntawm tus nqi tsim nyog (feem ntau qeeb txias, qee zaus tswj kom txias) ntawm ib hom kev kho mob annealing leveling.

5. Pickling: titanium phaj yog immersed nyob rau hauv ib tug pickling dej tov kom tshem tawm oxides thiab lwm yam nyias films nyob rau hauv cov hlau nto.
