Qhov sib txawv tseem ceeb ntawm kev hloov pauv thiab cov tshuaj sib xyaw ua ke yog qhov kev hloov pauv cov khoom siv cuam tshuam nrog kev hloov pauv ntawm cov kuab tshuaj atom los ntawm cov kua atom, hauv nws qhov tsim. Ntawm qhov tsis sib xws, tsis muaj qhov hloov pauv ntawm cov kuab tshuaj atoms los ntawm cov kuab atoms hauv kev tsim cov khoom sib xyaw ua ke, es tsis txhob, cov kua molecules nkag mus rau hauv lub qhov ntawm cov kuab atoms.
Ib qho kev daws teeb meem yog ib qho kev daws teeb meem hauv lub xeev ntawm ib los yog ntau dua cov kuab tshuaj hauv tib cov kuab tshuaj. Nyob ntawd, ob lossis ntau lub ntsiab lus tshwm sim hauv lub xeev khov. Peb hu nws txoj kev daws teeb meem es tsis yog qhov sib xyaw vim tias cov qauv siv lead ua ntawm cov kuab tshuaj tseem tsis hloov nrog qhov sib ntxiv ntawm cov kuab tshuaj. Nyob rau hauv cov txheej txheem ntawm cov khoom siv ntxiv dag zog, lub zog ntawm cov hlau ntshiab tuaj yeem nce ntxiv ntawm alloying lwm cov khoom. Peb tuaj yeem ua qhov no los ntawm kev tsim ib qho kev daws teeb meem. Nyob ntawm cov khoom siv alloying, muaj ob hom kev daws teeb meem raws li kev hloov pauv thiab cov kev daws teeb meem interstitial.
Kev Hloov Kho Khoom Ua Haujlwm yog dab tsi?
Substitutional solid solutions is solid-state solutions that form when the solute atoms replace the solvent atoms. Txhawm rau tsim cov tshuaj zoo li no, cov kua atoms yuav tsum loj txaus los hloov cov kuab tshuaj atom hauv cov lattice. Cov solute atoms suav nrog rau hauv cov lattice hloov pauv los ntawm kev hloov cov atoms hauv cov haujlwm tshwj xeeb ntawm cov lattice. Ntawm no, qee cov ntsiab lus alloying muaj cov atoms uas muaj peev xwm los hloov cov kuab tshuaj atoms tsuas yog me me thaum muaj qee cov ntsiab lus alloying uas tuaj yeem hloov cov kuab tshuaj atoms thoob plaws hauv cov tshuaj.
Hom kev daws teeb meem no tshwm sim thaum cov kuab tshuaj thiab cov kuab tshuaj atoms muaj ze li qhov sib xws atomic loj. Tsis tas li ntawd, qhov kub thiab txias tuaj yeem nce cov kev hloov pauv no. Tsis tas li ntawd, muaj ob hom kev hloov pauv cov kev daws teeb meem uas yog; kev txiav txim thiab tsis meej pem cov kev daws teeb meem. Ib daim ntawv txiav txim siab daws teeb meem thaum cov kua atoms hloov cov kuab tshuaj atoms hauv qhov chaw nyiam ntawm cov kuab tshuaj lattice. Ex: Cu-Au system. Cov kev daws teeb meem tsis sib haum xeeb tsim thaum cov kua atoms hloov pauv cov kuab tshuaj atom hauv cov lattice.
Interstitial Solid Solution yog dab tsi?
Interstitial solid solutions yog cov kev daws teeb meem hauv lub xeev uas tsim thaum cov atoms solute nkag mus rau hauv lub qhov nruab nrab ntawm cov kuab tshuaj atom ntawm lattice. Nyob ntawd, cov solute atoms me me txaus nkag mus rau hauv cov qhov. Peb hu cov qhov no, qhov chaw interstitial.
Daim duab 01: Ib qho kev daws teeb meem Interstitial
txheej txheem no ua rau cov kev sib raug zoo ntawm cov kuab tshuaj atoms tsis muaj zog. Yog li ntawd, lub lattice deforms. Txhawm rau ua qhov no, qhov loj me ntawm atomic ntawm cov atoms yuav tsum tsawg dua 40% ntawm qhov loj ntawm cov kuab tshuaj atoms. Solute atoms nkag mus rau hauv lub lattice interstitially. Tsuas yog cov ntsiab lus uas muaj peev xwm tsim tau hom kev daws teeb meem no yog H, Li, Na thiab B.
Qhov txawv ntawm Kev Hloov Hloov thiab Kev Sib Koom Tes Sib Koom Tes yog dab tsi?
Substitutional solid solutions is solid-state solutions that form when the solute atoms replace the solvent atoms. Hom kev daws teeb meem no tsuas yog yog tias cov atoms loj txaus los hloov cov kuab tshuaj atom hauv cov lattice. Ntxiv mus, qhov loj ntawm atomic ntawm cov kuab tshuaj yog ze li qhov loj ntawm cov kuab tshuaj atoms. Interstitial solid solutions yog cov kev daws teeb meem hauv lub xeev uas tsim thaum cov atoms solute nkag mus rau hauv qhov nruab nrab ntawm cov kuab tshuaj atoms ntawm lattice. Cov kev daws teeb meem no tsuas yog tsim tau yog tias cov atoms me me txaus nkag mus rau hauv lub qhov ntawm cov lattice. Tsis tas li ntawd, atomic loj ntawm solute atoms yuav tsum yog li 40% ntawm qhov loj ntawm cov kuab tshuaj atoms nyob rau hauv thiaj li yuav tsim hom lattice. Qhov no yog qhov sib txawv tseem ceeb ntawm kev hloov pauv thiab cov khoom sib xyaw ua ke.
Summary – Hloov pauv vs Interstitial Solid Solution
Cov kev daws teeb meem yog cov kev daws teeb meem hauv lub xeev uas muaj ob lossis ntau hom ntsiab lus hauv tib lub xeev cov khoom sib xyaw. Muaj ob hom kev daws teeb meem raws li kev hloov pauv thiab cov kev daws teeb meem interstitial raws li nws cov ntaub ntawv. Qhov sib txawv ntawm kev hloov pauv thiab qhov sib txawv ntawm cov khoom sib txawv yog tias nyob rau hauv kev tsim cov khoom siv hloov pauv, nws cuam tshuam txog kev hloov pauv ntawm cov kuab tshuaj atom los ntawm cov kuab atom thaum tsim cov kuab tshuaj interstitial, tsis muaj kev hloov pauv ntawm cov kuab atom los ntawm cov atoms. Tsis tas li ntawd, cov solute molecules nkag mus rau hauv lub qhov ntawm cov kuab tshuaj atoms.
