Ib qho ntawm feem ntau siv titanium alloys yog qib 5. Nws muaj zog heev thiab tiv taus xeb zoo. Txawm li cas los xij, nws yog ib qho nyuaj rau nrhiav seamless titanium raj tsim los ntawm Qib 5 cov khoom ntawm lub khw, ob qho tib si hauv tsev thiab txawv teb chaws.
Qib 5 titanium feem ntau yog ua los ntawm cov ntawv hlau. High-strength, tuab-walled Qib 5 titanium raj feem ntau yog tsim los ntawm kub extrusion los yog oblique perforation, thiab muaj nyob rau hauv lub khw. Cov yob classic, los yog dov, yuav tsum tau txhim kho rau cov txheej txheem rhuab dov. Lub tshuab raj muaj lub tshuab cua sov induction, thiab cov cuab yeej ua haujlwm muaj cov qauv tsim, kev tsim khoom nyuaj, thiab cov nqi tsim khoom siab. Lub hauv paus tseem ceeb ua rau cov xwm txheej tam sim no yog qhov nyuaj ntawm kev ua kom txias vim yog lub zog siab ntawm Qib 5 titanium alloys. Lub tsev kawm ntawv thiab kev lag luam tau koom tes los ua ntau txoj kev tshawb fawb txhawm rau txhawm rau hais txog cov thev naus laus zis tseem ceeb ntawm Qib 5 seamless txias dov forming.High-strength titanium alloy kav tuaj yeem tsim tau siv txoj kev ncaj qha txias dov txoj kev ntawm tus nqi qis dua thaum tseem ua tau raws li qhov xav tau ntawm kev ua haujlwm siab titanium alloy daim ntaub ntawv.
Lub raj blanks tau dov rau hauv ob lub raj nrog tag nrho deformation ntawm 70 feem pua los ntawm ob qhov kev hla thiab peb hla, raws li, siv txoj hauv kev sib txawv ntawm deformation ntau npaum li cas. Lub qhov cub txias rau 500 degree thiab coj mus rau chav tsev kub tom qab lub tshuab nqus tsev vacuum ntawm 800 degree nrog rau ib teev ntawm kev hla. Saib seb lub microstructure thiab lwm yam ntxwv hloov zuj zus. xaus:
1.Large deformations yog qhib thiab cov phab ntsa thickness sib txawv yog txiav txim siab, uas yuav cuam tshuam rau phab ntsa thickness sib txawv ntawm cov yeeb nkab kis tau los ntawm cov nram qab no passes. Nyob rau hauv cov ntaub ntawv ntawm ib tug me ntsis degree ntawm deformation, phab ntsa thickness sib txawv me me, thiab cov nto roughness yog maj txo.
2.Thaum lub zuag qhia tag nrho deformation yog tib yam, tus naj npawb ntawm dov hla dhau ua rau elongation, hardness, thiab lub zog ntawm cov yeeb nkab. Kev ua tau zoo thoob plaws lub rooj tsavxwm muaj zog.
3.Material flows nyob rau hauv lub loj deformation rolling coj daim ntawv ntawm ib tug sawb, whereas cov ntaub ntawv ntws nyob rau hauv lub me me deformation tus nqi coj daim ntawv ntawm bundles. Qhov loj deformation tus nqi yog attained los ntawm blanking lub tsim tube yog hais tias lub tshav kub kev kho mob tej yam kev mob ntawm kis thiab lub tom ntej dov lub lag luam yog tib yam. Txawm tias hnyav dua, lub koom haum yog distorted.
4.Ib qho me me ntawm deformation tsis muaj qhov cuam tshuam rau anisotropic rau cov khoom siv yeeb nkab; Txawm li cas los xij, muaj qee qhov kev hloov pauv hauv anisotropy ntawm cov khoom siv tshuab thaum lub sij hawm ntau dhau dov.
