Nyob rau hauv lub "hnub qub qeb" ntawm cov khoom siv,titanium alloys, nrog lawv ntau yam zoo xws li lub teeb yuag, siab zog, thiab corrosion kuj, tau dhau los nrhiav tom qab hauv aerospace, marine engineering, thiab biomedicine. Hardness, raws li nws cov core mechanical taw qhia, ncaj qha txiav txim siab ntawm daim ntawv thov scenarios, kev ua, thiab txawm tias qhov kev txwv ntawm titanium alloys.
Los ntawm precision kho mob implants mus rau aero- cav hniav, txhua daim ntawv thov ntawm titanium alloys cia siab rau kev tswj kom meej ntawm qhov hardness Performance index. Niaj hnub no, peb yuav nthuav tawm cov txheej txheem hardness ntawm titanium alloys thiab sib tham txog cov ntaub ntawv kev tshawb fawb tom qab qhov taw qhia tseem ceeb no.
Yuav ntsuas qhov hardness ntawm titanium alloys li cas?
Peb tus qauv ntsuas ntsuas txhua tus muaj lawv tus kheej tsom. Hardness yog cov khoom muaj peev xwm tiv thaiv cov yas deformation hauv zos. Kev ntsuam xyuas hardness ntawm titanium alloys tsis yog ib qho nqi, tab sis yog ib qho kev ntsuas kev ntsuas. Cov kev sim sib txawv sib txawv ntawm cov ntawv thov sib txawv, thiab cov txiaj ntsig kuj txawv. Xaiv qhov taw qhia kom raug yog tus yuam sij.
Isostatic Vickers hardness (HV):
Lub "kub standard" rau precision xeem. Nws suav nrog kev tsim ib qho indentation ntawm cov khoom nto nrog lub indenter los xam cov load rau ib cheeb tsam. Nws muaj qhov raug siab thiab yog txoj hauv kev zoo tshaj plaws rau kev ntsuas hardness ntawm precision -machined qhov chaw. titanium alloys feem ntau muaj HV tus nqi ntawm 250 thiab 350. Piv txwv li, TC4 titanium alloy, feem ntau siv hauv aerospace, tuaj yeem ncav cuag HV ntawm 350, nthuav tawm zoo heev tiv thaiv deformation. Nws yog tshwj xeeb tshaj yog haum rau kev sim nyias- cov phab ntsa, tiv thaiv deformation ntawm substrate.
Rockwell Hardness (HR):
Ib qho "cov cuab yeej ntsuas ceev" ntawm cov khoom siv hauv pem teb, siv lub pob zeb diamond los yog lub pob steel indenter, tus nqi hardness yog txiav txim los ntawm qhov tob indentation. Kev ntsuas kev ua tau zoo yog qhov siab heev, thiab tsis tas yuav tsum muaj kev suav nyuaj. Tus nqi HR ntawm titanium alloys feem ntau yog nyob nruab nrab ntawm 20 thiab 40, uas zoo kawg nkaus haum rau kev sim sai hauv kev tsim khoom loj thiab txhim kho kev ua haujlwm zoo.
Brinell hardness (HB):
Ib "tus yam ntxwv tshwj xeeb" ntawm ntxhib- cov ntaub ntawv nplej / annealed. Hardness yog xam los ntawm kev ntsuas lub indentation txoj kab uas hla tom qab siv ib tug tshwj xeeb load nrog ib tug steel pob indenter. Rau titanium alloys, tus nqi HB feem ntau yog 100-200, ua rau nws zoo dua rau kev sim hardness ntawm annealed los yog ntxhib- cov ntaub ntawv grained. Nws qhia meej txog qhov tsis kam ntawm cov ntaub ntawv no rau cov yas deformation. Cias muab, xaiv HV rau qhov precision, HR rau batch kuaj, thiab HB rau annealed / coarse-grained qhov chaw. Xaiv tus nqi tsim nyog raws li cov khoom siv thiab cov kev xav tau ntawm daim ntawv thov yuav ua rau cov ntaub ntawv hardness zoo tshaj plaws.
Cov titanium alloys sib txawv muaj cov txheej txheem sib txawv thiab cov txheej txheem kho cua sov, uas ua rau muaj kev hloov pauv loj hauv hardness. Tsis tas li ntawd, lub xeev ua haujlwm cuam tshuam rau qhov hardness tus nqi -piv txwv li, hardness ntawm txias - dov Gr5 tuaj yeem yog 30% siab dua li ntawm annealed Gr5, tab sis nws cov yas yuav txo qis raws li. Yog li ntawd, nyob rau hauv kev siv tswv yim, nws yog ib qhov tsim nyog los nrhiav qhov zoo tshaj plaws sib npaug ntawm hardness thiab toughness.
Gr1 (Industrial Pure Titanium): HV300, haum rau cov khoom siv tshuaj thiab cov kav dej hiav txwv desalination.
Gr2: HV320, siv nyob rau hauv nkoj propellers thiab tshav kub exchangers.
Gr5 (Ti6A14V): HV350, feem ntau siv hauv cov khoom siv hauv aerospace thiab cov pob qij txha.
Ti60: HV245, tshwj xeeb tshaj yog rau siab -cov khoom kub hauv aero- cav.
Ti6A17Nb: HV350, haum rau biomedical implants (tsis tshua muaj elastic modulus).
