Grain Size Analysis

 

Lub zog thiab Hardness Prediction: Nyob rau hauv BV / DH40 steel daim hlau, ib tug me me grain loj feem ntau implies siab zog thiab hardness. Qhov no yog vim tias cov ciam teb tuaj yeem cuam tshuam qhov kev txav ntawm kev txav mus los, thiab ntau thaj tsam ntawm cov nplej (tsim los ntawm cov nplej me) tuaj yeem tiv thaiv kev tawg, yog li txhim kho cov khoom tiv thaiv deformation. Piv txwv li, los ntawm kev soj ntsuam cov qoob loo loj los ntawm lub tshuab ntsuas metallurgical, yog tias cov nplej tau pom tias zoo thiab tsis sib xws, nws tuaj yeem kwv yees ua ntej tias cov phaj hlau muaj lub zog thiab hardness thiab tsim nyog rau cov khoom siv hauv nkoj uas dais. loj pressures los yog tej zog.

 

Electromagnetic Property Inference: Cov qoob loo loj kuj cuam tshuam rau cov khoom siv hluav taws xob. Finer nplej feem ntau ua rau cov hluav taws xob ruaj khov thiab sib nqus permeability ntawm cov khoom. Coarser nplej, ntawm qhov tod tes, yuav txo tau hluav taws xob conductivity. Tsis tas li ntawd, thaum kuaj xyuas electromagnetic, qhov tsis sib xws ntawm microstructure tshwm sim los ntawm cov nplej ntxhib yuav ua rau muaj kev sib txawv thiab txo qis ntawm cov teeb liab electromagnetic. Yog li ntawd, kev txheeb xyuas cov qoob loo loj yog pab tau rau kev kwv yees lub teeb liab teb ntawm cov khoom thaum lub sij hawm electromagnetic detection txheej txheem thiab tom qab ntawd ntsuam xyuas nws muaj peev xwm cuam tshuam nrog kev ntes tawg.

Phase Composition Analysis

 

Kev ntsuas kev ua tau zoo tom qab kev kho cua sov: BV / DH40 steel daim hlau yuav tsim cov theem sib txawv tom qab sib txawv cua sov - txheej txheem kho. Piv txwv li, tom qab quenching thiab tempering, theem xws li martensite thiab tempered sorbite yuav tshwm sim. Lub martensite theem feem ntau muaj cov hardness siab thiab lub zog, tab sis nws cov toughness kuj tsawg; lub tempered sorbite theem muaj zoo toughness thiab zoo txhua yam khoom. Los ntawm kev txheeb xyuas qhov kev faib ua feem thiab kev faib tawm ntawm cov theem no, lub zog, toughness, hnav tsis kam thiab lwm yam khoom ntawm steel phaj tuaj yeem kwv yees. Piv txwv li, yog tias qhov kev faib ua feem ntawm cov theem martensite nyob rau hauv cov hlau phaj yog qhov siab, nws qhov hardness kuj yuav siab, tab sis nws yuav ua rau cov tawg tawg ntau dua thaum siv, thiab cov kev tiv thaiv sib xws yuav tsum tau xav txog hauv kev tsim thiab siv.

 

Electromagnetic Property Prediction: Cov theem sib txawv muaj cov khoom sib txawv electromagnetic, xws li hluav taws xob conductivity thiab magnetic permeability. Thaum txheeb xyuas cov theem muaj pes tsawg leeg, nkag siab txog cov khoom siv hluav taws xob ntawm txhua theem thiab lawv qhov kev faib tawm hauv cov phaj hlau ua rau kev kwv yees ntawm tag nrho cov lus teb electromagnetic ntawm cov khoom. Piv txwv li, yog tias muaj ntau theem nrog cov hluav taws xob hluav taws xob siab hauv cov hlau phaj, cov teeb liab nthuav tawm thiab kev xav thaum lub sij hawm kuaj electromagnetic yuav txawv ntawm cov hlau phaj nrog ntau theem ntawm cov hluav taws xob tsis tshua muaj hluav taws xob. Qhov no yog ib qho tseem ceeb heev rau kev ua kom raug electromagnetic kev khiav hauj lwm xws li kev ntsuam xyuas tawg.
