Kev tshuaj xyuas lub hauv paus ntsiab lus ntawm Vibration Stress Relief Treatment
Vibration stress relief kho (VSR) yog raws li lub hauv paus ntsiab lus ntawm resonance, ua rau lub workpiece vibrate ntawm ib tug tsim nyog vibration zaus. Thaum lub sij hawm vibration txheej txheem, cov residual kev nyuaj siab nyob rau hauv cov khoom yuav tsum redistributed thiab so. Rau cov khoom siv hlau LR FH36 steel, qhov kev hloov pauv ntawm qhov kev ntxhov siab yuav muaj kev cuam tshuam rau nws qhov hardness.

 

Cov xwm txheej uas tuaj yeem ua kom tawv tawv
Txhim khu kev txav mus los thiab kev sib cuam tshuam: Thaum lub sij hawm vibration stress relieving process, dislocations hauv cov khoom yuav txav mus. Thaum cov dislocations txav mus rau ib qho twg, kev sib cuam tshuam ntawm dislocations yog txhim kho. Piv txwv li, dislocations yuav entangle nrog ib leeg los yog tsim ib tug dislocation phab ntsa. Cov kev hloov pauv hauv cov qauv dislocation yuav ua rau cov khoom tiv thaiv kom deformation. Nws zoo li ntxiv ntau "kev cuam tshuam" ntawm qib microscopic, ua rau nws nyuaj rau cov khoom siv rau plastically deform thaum raug rau sab nraud quab yuam, yog li ua kom cov tawv tawv.
Muaj peev xwm cuam tshuam ntawm Grain Refinement: Qee zaum, kev kho kev ntxhov siab ntawm kev co tuaj yeem ua rau cov nplej ua kom zoo dua ntawm LR FH36 steel. Thaum lub grain loj me me, lub grain ciam cheeb tsam yog kuj nce. Lub ciam teb nplej yog ib qho tseem ceeb uas cuam tshuam qhov kev txav ntawm kev txav mus los vim qhov kev cuam tshuam yuav raug thaiv ntawm cov ciam teb nplej thiab tsis tuaj yeem hla mus tau zoo. Ntau thaj tsam ntawm cov nplej txhais tau tias muaj kev cuam tshuam ntau dua, yog li cov khoom siv yuav tsum muaj lub zog ntau dua los ua kom deform thaum raug rau sab nraud quab yuam, uas yuav ua rau muaj kev nce hauv cov khoom hardness.

Cov xwm txheej uas yuav txo qis Hardness
Kev so ntau dhau ntawm kev ntxhov siab ntau dhau: Yog tias qhov tsis zoo ntawm kev co kev ntxhov siab kho tsis tau teeb tsa kom zoo, xws li lub sijhawm vibration ntev dhau los lossis qhov kev vibration ntau dhau lawm, nws yuav ua rau muaj kev ntxhov siab ntau dhau ntawm cov khoom seem hauv cov khoom. Nyob rau hauv cov ntaub ntawv no, lub hardening nyhuv ntawm cov khoom mus rau ib tug tej yam raws li cov residual kev nyuaj siab disappears. Piv txwv li, qhov kev ntxhov siab nyob rau hauv tuaj yeem tso cov qauv siv lead ua rau hauv cov khoom siv hauv lub xeev "compressed", thiab lub xeev no ua rau muaj kev nyuaj siab rau qee yam. Thaum cov kev ntxhov siab uas seem yog so ntau dhau, qhov "compressed" lub xeev no raug tso tawm, thiab lub hardness yuav raug txo.
Kev nce hauv Micro - Cov yam ntxwv tsis xws luag: Kev co ntau dhau tuaj yeem ua rau micro - cov yam ntxwv tsis xws luag hauv cov khoom, xws li cov kab nrib pleb me me lossis cov voids. Cov kev tsis zoo no yuav ua rau tsis muaj zog tag nrho ntawm cov khoom siv, ua rau nws yooj yim dua rau cov khoom kom deform ntawm qhov chaw tsis xws luag thaum raug rau sab nraud quab yuam, yog li txo cov khoom hardness.
