Titanium qhov zoo tshaj plaws corrosion kuj thiab lub zog tshwj xeeb ua rau cov kav dej titanium thinner thiab muaj txiaj ntsig zoo dua cov khoom siv hluav taws xob zoo dua li cov khoom ua los ntawm lwm cov khoom siv hlau cov yeeb nkab fittings. TC4 titanium alloy yog ib qho ntawm feem ntau siv titanium alloys tam sim no. Nws muaj lub zog siab thiab zoo corrosion kuj.
Siv txoj kev sib txawv deformation, lub raj blanks yog dov rau hauv cov kav dej nrog tag nrho deformation ntawm 70% los ntawm ob thiab peb dhau ntawm dov. Nqus annealing yog ua nyob rau ntawm 800 degree × 1h ntawm kis. Txoj kev ua kom txias yog kom txias rau qhov cub kom 500 degree thiab tom qab ntawd cua-txias mus rau chav sov kom pom qhov kev hloov ntawm nws cov microstructure thiab cov khoom. xaus:
Thaum lub billet qhib nrog me me deformation, phab ntsa thickness sib txawv me me thiab cov nto roughness maj mam txo; Thaum lub billet qhib nrog ib tug loj deformation, lub phab ntsa thickness sib txawv yog loj, uas yuav cuam tshuam rau phab ntsa thickness sib txawv ntawm cov yeeb nkab uas tau los ntawm tom ntej dhau ntawm dov.
Thaum tag nrho cov deformation zoo ib yam, qhov ntau dov dhau, qhov ntau dua qhov elongation, hardness, thiab lub zog ntawm cov yeeb nkab. Kev ua tau zoo tag nrho.
Thaum dov nrog loj deformation, ntws ntawm cov khoom yog nyob rau hauv daim ntawv ntawm strips. Thaum dov nrog me me deformation, qhov ntws ntawm cov khoom yog nyob rau hauv daim ntawv ntawm bundles. Thaum cov txheej txheem kev kho cua sov thiab cov txheej txheem dov tom ntej ntawm kev sib kis yog tib yam, cov kav dej tau txais los ntawm blanking nrog loj deformation Cov ntaub so ntswg distortion yog hnyav dua.
Me me deformation blanking muaj me ntsis cuam tshuam rau anisotropy ntawm cov yeeb nkab; muaj qee qhov kev hloov pauv hauv anisotropy ntawm cov khoom siv kho tshuab thaum lub sij hawm ntau dhau dov.
