Titanium alloy dov blanks feem ntau yog loj-loj forged rods. Vim muaj qhov sib txawv ntawm cov cua txias, cov qauv ntawm cov pas nrig forged ntawm chav tsev kub yog ib qho kev hloov pauv hauv daim ntawv ntawm rab koob zoo li, nplua flakes lossis tuab flakes.
Cov qauv no muaj kev nkag siab siab thiab tawg toughness, tab sis tsis muaj zog qaug zog thiab tensile plasticity. Kev ua ntawm titanium alloy rods feem ntau vam tias yuav tau txais cov qauv equiaxed nrog zoo tensile thiab qaug zog zog. Txawm li cas los xij, cov qauv lamellar ntawm tus pas nrig forged yog qhov ruaj khov ntawm chav tsev kub, thiab nws tsuas tuaj yeem ua equiaxed los ntawm muaj zog deformation nyob rau hauv ob-theem cheeb tsam, yog li lub siab deformation kuj thiab nyuaj rau deformation ntawm titanium alloys nyob rau hauv chav tsev kub yog ib tug. ntawm cov laj thawj uas txwv txoj kev dov ntawm titanium alloys. Yog li ntawd, lub dov txoj kev ntawm titanium alloys feem ntau yog ua nyob rau hauv ib tug tej yam kub thiab txias.
Qhov loj ntawm dov deformation yog qhov zoo rau kev kho cov qauv thiab txhim kho cov khoom siv kho tshuab; qhov me me ntawm dov deformation tsuas yog ua rau lub zog rov qab thaum lub sijhawm dov. Txawm li cas los xij, titanium alloy muaj cov yas tsis zoo thiab me me deformation hauv txhua qhov dhau los. Yog li ntawd, cov qauv ntxhib ntawm titanium alloy vim me me deformation hauv kev hla yog ib qho tseem ceeb ntawm yob txoj kev.
Lwm tus yam ntxwv ntawm titanium alloy yob txoj kev yog tias cov txheej txheem dov yuav tsum muaj ntau yam annealings. Nyob rau hauv ib qho chaw qhib dov, cov cua sov hloov ntawm cov hlau, cua, yob, thiab lwm yam ua rau qhov kub thiab txias ntawm cov khoom dov poob sai heev. Qhov kub ntawm qhov nruab nrab ntawm cov dov daim ntawv nce es tsis txhob vim deformation thiab kub tiam, ua ib tug loj kub ntawm qhov chaw thiab qhov chaw. Gradient, nto tawg yog nquag tshwm sim thaum lub sij hawm dov txheej txheem.
Txhawm rau kom ntseeg tau tias dov yog nyob rau hauv qhov ntsuas kub thiab qhov ntsuas kub ntawm cov khoom dov yog qhov sib xws, cov dov yuav tsum tau ua kom sov ntawm cov hlaws. Tsis tas li ntawd, vim qhov sib txuam ntawm cov menyuam ntxaib thiab kev ntxhib los mos thiab ua haujlwm tawv thaum lub sijhawm dov, dov deformation ua nyuaj zuj zus. Yog li ntawd, txhawm rau txuas ntxiv deformation, lub dov daim ntawv yuav tsum tau ua kom sov ntawm qhov kev hla mus ua kom muaj ntau tus menyuam ntxaib tshwm sim. Recrystallization txhim kho cov yas ntawm cov khoom thiab tiv thaiv cov khoom los ntawm kev tawg thaum lub sij hawm tom qab dov.
