Puas yog Titanium yooj yim deformed?
Nyob rau hauv lub ntiaj teb ntawm cov ntaub ntawv metallic, titanium tau nyiam ntau dua vim nws tshwj xeeb lub cev thiab ntau ntawm cov ntawv thov. Qhov kev sib txuas no - transitition hlau tsis tsuas yog muaj cov khoom siv hluav taws xob tsis zoo thiab cov khoom siv lub hnub qub xws li aerospace, tshuaj, thiab tshuaj lom neeg, thiab tshuaj lom neeg. Txawm li cas los xij, cov lus nug ntawm seb Titanium puas yooj yim deformable yuav tsum muaj nyob rau hauv {4} ecte ntawm cov ntaub ntawv kev tshawb fawb, thiab cov ntaub ntawv ntsuas kev tswj hwm, thiab cov ntaub ntawv thov kev tsim txiaj.
Crystal qauv thiab deformation hauv paus ntawm titanium
Cov yam ntxwv deformation ntawm titanium yog ze rau nws cov qauv siv lead ua. Hauv qab 882.5 degree, titanium muaj raws li theem nrog hexagonal kaw- packed (HCP) qauv; Thaum qhov ntsuas kub tshaj qhov tseem ceeb tshaj plaws no, nws hloov mus rau theem nrog lub cev {{3} Chaw Sau Lus (BCC) qauv. Qhov kev hloov pauv npib ob xaus xaus rau cov menyuam ntxiab tau ua ke, tab sis kuj tseem tuaj yeem ua rau muaj cov menyuam ntxau tau, tab sis, -}}}}}}}}}}} pa taws lub zog, cov khoom pov thawj ua kom muaj zog yas deformation muaj peev xwm ntawm cov kub. Piv txwv li, hauv kev tsim khoom ntawm Aero - Cav}}}}}} {{14} {{14} -
Kev tswj ntawm Titanium deformation cwj pwm los ntawm kev ua tshuab
Thaum Titanium kev ua haujlwm tsis zoo li cov ntaub ntawv ib txwm muaj xws li txhuas alloys, nws lub peev xwm deformation tuaj yeem txhim kho kom zoo dua los ntawm cov txheej txheem txhim kho. Kev lom zem ua ib qho piv txwv, ntshiab titanium tuaj yeem ua tiav qhov kev tawm tsam ntawm 70% -80% ntawm kev ua kom muaj zog ntawm 70% Cov neeg tsis txaus siab qeeb txo kev ntxhov siab sab hauv, thaum muaj kev cuam tshuam sai sai ua kom cov nplej zom thiab txhim kho lub zog. Nyob rau hauv cov txheej txheem ROB, Titanium cov khoom yuav tsum tau mus rau ntau yam kev tawm tsam ntawm kev ua haujlwm kub, thiab thaum kawg tau txais daim hlau nrog cov phaj tuab thiab ua haujlwm ruaj khov. Ib lub tuam txhab titanium alloy ua kev sib tw txias melanth
Ob npaug -}} edged ntaj cuam tshuam ntawm titanium txoj haujlwm deformation
Titanium qhov deformivion coj ob qho zoo thiab kev cov nyom. Hauv kev kho tsev kho mob, Titanium's biocompatibility thiab me ntsis cov khoom siv thiab kev cog hniav loj heev (kwv yees li ntawm 110 GPA) yog ze rau ntawm tib neeg cov pob txha, zam kev ntxhov siab thaiv cov teebmeem; Nws cov yeeb yaj kiab Oxide Oxide (kwv yees li 2 {}}}}}}}}} Micrometers los ntawm electrolytic polishing, txo cov kab mob adcelion. Txawm li cas los xij, titanium muaj ib qho kev ua haujlwm tseem ceeb rau kev ua haujlwm hnyav, yooj yim tsim kom muaj cov khoom siv carbide thiab siab {{}} kub txias; Thaum lub sijhawm vuam Ib qho chaw tsim hluav taws xob tsim kho cov vuam hla tus nqi ntawm titanium alloy tso manifolds los ntawm 75% los ntawm kev siv laser vuam tshuab.
Yav Tom Ntej: Los ntawm deformation tswj rau cov neeg ntse tsim khoom
Nrog kev tawg nyob rau hauv cov thev naus laus zis xws li 3D luam thiab nyob rau ntawm {}}} let}}} Kev tswj ntawm titanium yog nkag mus rau theem tshiab. Kev siv hluav taws xob melting (EBM) thev naus laus zis tuaj yeem luam tawm cov khoom siv titanium alloy nrog cov khoom siv pov tseg; Kev Kho Mob Kub Kub Kub (TMCP), los ntawm Coupling deformation thiab kev kho cua sov, tuaj yeem ua tiav cov qoob loo nplej thiab kev ua tau zoo hauv ib qho txheej txheem. Cov lag luam kev tshawb fawb ua lag luam twv tau hais tias los ntawm 2030, kev siv thoob ntiaj teb yuav loj hlob ntawm ib nrab xyoo ntawm 8.2% thiab cov kws kho mob nce qib 15%. Raws li lub ntiaj teb cov khoom tsim tawm loj tshaj plaws, Tuam Tshoj tawg los ntawm kev ua haujlwm siab tshaj plaws hauv kev lag luam, kev tshawb fawb, thiab cov khoom kim heev "rau ib qho" loj}} kev lag luam hwm. "
Qhov deformity ntawm titanium yog cov khoom lag luam khoom siv cov khoom siv, kev txawj ntse thev naus laus zis, thiab kev xav tau kev paub txog kev paub. Nws tsis yog "yooj yim deformable" mos hlau tsis yog "nyuaj}- Los ntawm lub siab - tiv taus plhaub - lub hiav txwv prester rau cov tshooj tshiab nrog nws cov lus tshwj xeeb nrog nws cov lus tsis zoo.
