Titanium muaj qhov zoo ductility, ua kom nws yooj yim tsim rau hauv cov duab sib txawv. Cov cuab yeej no yog qhov zoo rau forging, raws li nws tso cai rau cov hlau mus rau cov yas deformation nyob rau hauv compressive rog.
5. Biocompatibility:
Lwm yam khoom tseem ceeb ntawm titanium yog nws biocompatibility. Nws yog dav siv nyob rau hauv kev kho mob daim ntawv sau npe, xws li cog thiab phais, vim nws muaj peev xwm mus integrate nrog tib neeg lub cev yam tsis muaj kev phiv tshwm sim.
Txheej txheem Forging:
Forging yog cov txheej txheem tsim khoom uas suav nrog kev tsim cov hlau los ntawm lub zog compressive hauv zos. Nws feem ntau suav nrog cua sov cov hlau mus rau qhov kub thiab txias thiab tom qab ntawd siv cov cuab yeej siv rauj, nias, lossis dov. Cov txheej txheem ua rau muaj kev txhim kho cov khoom siv kho tshuab thiab txhim kho kev ncaj ncees ntawm cov hlau forged.
Kev tsim nyog ntawm titanium forging:
Xav txog cov khoom ntawm titanium, nws tsa cov lus nug ntawm seb nws puas yog cov khoom tsim nyog rau cov txheej txheem forging. Cia peb delve rau hauv cov yam uas txiav txim siab nws haum.
1. High Strength-To-Weight Ratio:
Qhov tshwj xeeb lub zog-rau-qhov hnyav piv ntawm titanium ua rau nws muaj kev xaiv zoo rau forging, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas xav tau lub zog siab thiab qhov hnyav. Piv txwv li, hauv kev lag luam aerospace, titanium forgings feem ntau yog siv los txo qhov hnyav ntawm lub dav hlau thaum tswj kev ua haujlwm zoo.
2. Corrosion Resistance:
Kev tiv thaiv corrosion ntawm titanium yog qhov zoo hauv kev siv forging, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas cov hlau degradation yog ib qho kev txhawj xeeb. Cov cuab yeej no ua kom ntseeg tau tias cov khoom siv titanium forged tuaj yeem tiv taus cov xwm txheej hnyav thiab tswj xyuas lawv cov qauv kev ntseeg siab dhau sijhawm.
3. High Melting Point:
Lub siab melting point ntawm titanium tso cai rau forging ntawm qhov kub thiab txias yam tsis muaj kev pheej hmoo ntawm kev ua tsis tiav ntxov. Cov cuab yeej no yog qhov tseem ceeb rau kev tswj xyuas qhov formability ntawm cov hlau thaum lub sij hawm forging txheej txheem.
4. Ductility:
Titanium's zoo ductility ua rau nws mus rau cov yas deformation thaum lub sij hawm forging txheej txheem. Cov cuab yeej no tso cai rau cov tuam txhab tsim cov hlau rau hauv cov ntawv xav tau yam tsis muaj kev tawg lossis tsis ua haujlwm.
5. Kev sib tw hauv Forging Titanium:
Txawm hais tias nws muaj ntau yam zoo, forging titanium nthuav qhia qee yam kev nyuaj uas yuav tsum tau daws.
a. Reactive Nature:
Titanium muaj kev sib raug zoo rau cov pa oxygen, nitrogen, thiab carbon, uas tuaj yeem ua rau muaj kev sib kis thaum lub sij hawm forging. Kev tuav kom raug thiab siv cov kev tiv thaiv kev tiv thaiv, xws li inert gas ib puag ncig, yog qhov tseem ceeb los tiv thaiv kev ua qias tuaj ntawm titanium.
b. High Cooling Rate:
Titanium muaj qhov txias txias, uas tuaj yeem ua rau muaj kev ntxhov siab thiab cuam tshuam hauv cov khoom forged. Ua tib zoo xav txog cov txheej txheem ua kom txias, xws li kev tswj kom txias lossis siv cov txheej txheem kho cua sov tshwj xeeb, tuaj yeem pab txo cov teeb meem no.
