Hauv kev txheeb xyuas EBSD, qhov cuam tshuam ntawm kev vibration kev ntxhov siab - kev kho mob ntawm qhov tawv tawv tuaj yeem txiav txim los ntawm cov yam ntxwv hauv qab no:

 

 

Grain Boundary Misorientation Distribution

 

Range of Misorientation Angles: Txheeb xyuas qhov kev faib tawm ntawm cov kaum sab xis ntawm ob sab ntawm cov qoob loo. Yog hais tias tus naj npawb ntawm cov ciam teb nrog cov misorientation loj dua los yog lawv qhov kev faib tawm ntau dua tom qab kev vibration kev ntxhov siab - kev kho mob, nws qhia tau hais tias cov nplej orientations hauv cov khoom muaj ntau haiv neeg, thiab dislocations yuav ntsib ntau yam teeb meem thaum tsiv ntawm cov nplej nrog txawv orientations. , yog li lub hardness yuav nce.

Correlation ntawm Misorientation thiab Hardness: Tsim kom muaj kev sib raug zoo ntawm misorientation thiab hardness. Los ntawm suav cov proportions ntawm grain ciam teb nrog sib txawv misorientations thiab lawv cov ntaub ntawv hardness coj, haum rau cov curves los yog sib npaug ntawm lawv. Raws li qhov kev sib raug zoo no, thaum txheeb xyuas qhov kev hloov pauv ntawm cov ciam teb misorientation tom qab kev vibration kev ntxhov siab - kev kho mob, qhov sib txawv ntawm hardness hloov tuaj yeem txiav txim tau ntau dua.

Grain Boundary Segregation thiab Phase Distribution

 

Element Segregation: Los ntawm kev sib txuas EBSD nrog lub zog spectrum tsom xam thiab lwm txoj hauv kev, nws tuaj yeem soj ntsuam seb puas muaj cov khoom sib cais ntawm cov ciam teb. Yog tias kev vibration kev ntxhov siab - kev kho mob ua rau muaj qee yam ntxiv dag zog rau kev sib cais ntawm cov ciam teb, ua kom muaj zog ntau ntxiv los yog nag lossis daus ntxiv zog, nws yuav cuam tshuam cov kev txav ntawm kev txav thiab ua kom cov tawv tawv.
