TC4 titanium alloy yog feem ntau siv titanium alloy tam sim no. Nws muaj lub zog siab thiab zoo corrosion kuj, tab sis nws yog ib qho nyuaj rau pom seamless titanium raj ua los ntawm TC4 khoom nyob rau hauv seamless titanium raj ua lag luam.
TC4 titanium cov ntaub ntawv feem ntau yog daim hlau. TC4 titanium raj nyob rau hauv kev ua lag luam feem ntau yog siab - lub zog, tuab- cov hlab ntsa uas ua los ntawm kub extrusion los yog oblique drilling. Cov txheej txheem sov dov yuav tsum tau txhim kho cov tsoos rollers, uas yog, kev teeb tsa ntawm induction cua sov rau ntawm lub raj dov zeb. Cov cuab yeej ua haujlwm no muaj cov qauv tsim, cov txheej txheem cumbersome, thiab cov nqi ntau lawm. Qhov laj thawj tseem ceeb yog tias cov txheej txheem lub zog ntawm TC4 titanium alloy yog siab thiab txias dov deformation load yog loj. Yuav kom daws tau qhov tseem ceeb thev naus laus zis ntawm txias dov deformation ntawm TC4 seamless raj, lub tsev kawm ntawv thiab cov tuam txhab koom ua ke ua cov kev tshawb fawb. Piv txwv li, ncaj qha txias dov deformation yog siv los tsim siab - lub zog titanium alloy raj, uas tsis tsuas yog txo cov nqi tsim khoom tab sis kuj ua tau raws li qhov yuav tsum tau muaj ntawm siab - kev siv siab ntawm titanium alloys.
Tube billet yog dov rau hauv ib lub raj nrog tag nrho deformation ntawm 70% los ntawm ob thiab peb hla, feem. Nqus annealing ntawm 800℃× 1h tau ua ntawm kev hla dhau. Txoj kev ua kom txias yog lub qhov cub txias rau 500℃thiab tom qab ntawd cua txias tam sim ntawd, thiab cov kev hloov hauv nws lub koom haum tau pom.
Cov lus xaus yog:
Nyob rau hauv cov ntaub ntawv ntawm me me deformation billeting, lub phab ntsa thickness sib txawv me me thiab cov nto roughness increment raug txo; Nyob rau hauv cov ntaub ntawv ntawm loj deformation billeting, phab ntsa thickness sib txawv yog loj, uas yuav cuam tshuam rau phab ntsa thickness sib txawv ntawm cov yeeb nkab tau los tom qab dov.
Nyob rau hauv tib lub deformation, qhov ntau dov dhau, qhov ntau dua qhov elongation thiab thickness ntawm cov yeeb nkab thiab lub zog nce. Kev ua tau zoo tshaj plaws yog qhov zoo.
Thaum dov nrog loj deformation, qhov ntws ntawm cov khoom yog strip -zoo li tus, thiab thaum dov nrog me me deformation, qhov ntws ntawm cov khoom yog bundle -zoo li tus. Nyob rau hauv tib lub tshav kub kev kho mob ntawm kis thiab tom ntej dov txheej txheem, lub koom haum distortion ntawm cov yeeb nkab tau los ntawm billeting nrog loj deformation yog loj dua.
Billeting nrog me me deformation muaj me ntsis cuam tshuam rau anisotropy ntawm cov yeeb nkab; muaj qee qhov hloov pauv hauv anisotropy ntawm cov khoom siv kho tshuab hauv ntau- dhau dov.
