Dab tsi Ua Rau Cov Ntse iav kom Dheev Txhaum?

Cov khoom siv tseem ceeb ntawm Ntse iav yog tempered iav. Cov laj thawj rau qhov tsis paub txog kev tawg ntawm lub iav tempered-Nickel sulfide (NiS) thiab cov theem sib txawv tau qhov twg los ntawm kev tswj tsis tau tawg ntawm lub iav tempered tsis yog nis tsuas yog nyob rau hauv kev nkag siab ib txwm, tab sis kuj tseem muaj ntau lwm qhov kev ua tiav theem. Qhov kev pib tawg thiab hais tawm hauv lub khob yog vim qhov muaj kev nyuaj siab tsim nyob ze cov lus. Hom kev ntxhov siab no tau muab faib ua ob pawg, ib qho yog theem kev hloov pauv kev ntxhov siab nyob rau theem nthuav dav thiab lwm qhov yog qhov kev nyuaj siab seem tshwm sim los ntawm qhov tsis sib haum ntawm lub thermal expansion coefficients. Nickel sulfide (nis) thiab heterogeneous particles. Lub iav muaj cov npib tsib xee sulfide impurities thiab muaj nyob hauv lub xeev ntawm cov muaju me me. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav tsis ua rau iav puas. Txawm li cas los xij, lub reheated tempered iav ntawm Smart Glass hloov cov theem theem lub xeev ntawm nickel sulfide impurities. Lub siab kub alpha lub xeev ntawm nickel sulfide yog Lub iav khov thaum nws quenched, thiab nws siv sijhawm rau lawv rov qab mus rau hauv lub xeev beta. Vim tias qhov txias kub tsawg beta lub xeev nickel sulfide impurities, lub ntim yuav nce ntxiv, thiab kev ntxhov siab hauv zos yuav tshwm sim hauv iav. Lub sijhawm no, lub iav tempered yuav tawg. Txawm li cas los xij, tsuas yog kev cuam tshuam loj yuav ua rau nws tus kheej tawg, thiab qhov ntsuas tus kheej ntawm lub khob iav tsuas yog tshwm sim thaum lub impurities yog qhov tseem ceeb ntawm qhov kev nyuaj siab tensile. Nws tuaj yeem pom los ntawm scanning hluav taws xob micrograph ntawm nis pob zeb muab rho tawm los ntawm tawg tawg ntawm Smart iav iav tom qab kev tshawb xyuas tus kheej tias qhov saum npoo yog undulating thiab ntxhib heev. Cov kabmob heterogeneous ua rau lub iav tempered tawg. Nws tuaj yeem pom hauv daim duab thau duab los ntawm iav tawg tsam ntawm qhov chaw ntawm qhov tawg taus.
