Nano-indentation Technique

 

Txoj Cai thiab Kev Ua Haujlwm: Cov txheej txheem nano-indentation tau txais cov khoom siv ntawm cov khoom siv los ntawm kev siv nano-scale loads ntawm cov khoom siv qhov chaw uas siv ib qho indenter nrog ib qho geometric duab (xws li daim duab peb sab pyramid los yog sphere) thiab tom qab ntawd ntsuas qhov tob indentation. Rau CCS F690 steel, cov qauv ua ntej thiab tom qab kev vibration-relief kho tau muab tso rau ntawm lub rooj ua haujlwm ntawm cov khoom siv nano-indentation. Kev hloov pauv ntawm lub indenter thiab lub zog thauj khoom yog tswj tau meej, thiab qhov kev hloov pauv ntawm qhov kev hloov pauv thaum lub sijhawm indentation txheej txheem raug kaw.

 

Analysis ntawm Nanomechanical Properties:

 

Kev ntsuas hardness: Lub hardness ntawm cov khoom yuav raug xam los ntawm lub load-tsav nkhaus. Piv txwv li, raws li Oliver-Phharr txoj kev, tus nqi hardness yog xam los ntawm kev txheeb xyuas qhov tsis xws li txoj kab nqes ntawm txoj kab nkhaus unloading. Los ntawm kev sib piv cov kev hloov ntawm hardness ua ntej thiab tom qab kev vibration kev nyuaj siab-relief kev kho mob, lub cawv ntawm cov txheej txheem kev kho mob ntawm hardness, uas yog ib tug ntawm cov nanomechanical zog ntawm cov khoom, tuaj yeem nkag siab ncaj qha.

 

Kev ntsuas Elastic Modulus: Nano-indentation tuaj yeem ntsuas qhov elastic modulus ntawm cov khoom los ntawm kev tshuaj xyuas qhov elastic deformation thaum lub sijhawm thauj khoom thiab tshem tawm cov txheej txheem. Lub elastic modulus qhia txog cov khoom muaj peev xwm los tiv thaiv elastic deformation. Yog hais tias qhov kev vibration-relief kev kho mob hloov lub sab hauv microstructure ntawm cov khoom, xws li cov dislocation ceev los yog grain loj, nws yuav tsum tau reflected nyob rau hauv cov kev hloov ntawm elastic modulus, thiaj li los soj ntsuam nws cov cawv ntawm lub nanomechanical zog.

 

Kev Tshawb Fawb Cov Khoom Siv Yas: Los ntawm kev soj ntsuam cov yas deformation nyob rau hauv lub load-tsav nkhaus, piv txwv li, tsom xam qhov seem seem ntawm qhov indentation, cov khoom yas ntawm cov khoom tuaj yeem kawm. Kev kho kev vibration-relief tej zaum yuav hloov cov yas deformation tus cwj pwm ntawm cov khoom, xws li ua rau nws nyuaj rau cov khoom mus undergo yas deformation los yog hloov nws lub zog tawm los. Cov kev hloov pauv no tuaj yeem txheeb xyuas los ntawm cov txheej txheem nano-indentation.

 

Kev sib xyaw ntawm Scanning Electron Microscopy (SEM) thiab Energy Dispersive Spectroscopy (EDS)

 

Txoj Cai thiab Kev Ua Haujlwm: SEM tuaj yeem muab cov kev daws teeb meem siab tshaj plaws microscopic topography dluab ntawm cov khoom nto, thaum EDS tuaj yeem txheeb xyuas cov tshuaj muaj pes tsawg leeg ntawm micro-chaw nyob ntawm cov khoom nto. Rau CCS F690 steel tom qab kev vibration-relief kev kho mob, SEM yog thawj zaug siv los soj ntsuam seb puas muaj cov kev hloov hauv microstructure ntawm cov khoom nto, xws li cov tsos ntawm cov kab nrib pleb, dislocation outcrops, los yog kev hloov ntawm cov nplej. Tom qab ntawd, EDS yog siv los tshuaj xyuas cov kev hloov pauv hauv cov tshuaj muaj pes tsawg leeg ntawm cov cheeb tsam no, vim tias kev hloov pauv ntawm cov tshuaj muaj pes tsawg leeg tuaj yeem cuam tshuam rau cov khoom ntawm cov khoom siv nanomechanical.
