Binary Isomorphous Systems
Thaum cov khoom (cov ntsiab lus) ntawm a binary system yog miscible kiag li (tag nrho soluble nyob rau hauv ib leeg) nyob rau hauv cov ntaub ntawv khoom, lawv tsim ib tug tas mus li kev daws teeb meem.
Hais txog qhov no, binary Isomorphous system yog dab tsi?
Ib isomorphous system yog ib qho uas cov khoom muaj tib yam qauv rau tag nrho cov compositions. Daim duab qhia theem qhia yog daim duab rau Cu-Ni, uas yog ib qho isomorphous hlau alloy qhov system . Isomorphous systems tsis muaj ntau, txawm tias muaj tus lej isomorphous systems siv. Cov tooj liab-nickel qhov system yog ib qho piv txwv.
Dab tsi yog hom kab kos duab? Muaj peb lub ntsiab hom ntawm binary cov duab kos duab : Ua kom tiav cov khoom ua kua thiab kua daim duab , Eutectic daim duab (xws li Eutectic daim duab nrog ib nrab solubility ntawm cov khoom hauv lub xeev thiab Eutectic daim duab nrog intermetallic compound) Peritectic daim duab.
Tsuas yog li ntawd, alpha thiab beta yog dab tsi hauv daim duab qhia theem?
Qhov twg ntawm cov khoom solubility cheeb tsam tuaj yeem npaj rau hauv Phaj daim duab . Hauv qhov piv txwv no, lub alpha theem yog thaj av ntawm cov kuab tshuaj uas qee cov B atoms tau yaj hauv cov matrix ntawm A atoms. Cov beta theem yog thaj av uas ib feem me me ntawm A atoms tau yaj hauv matrix ntawm B atoms.
Isomorphous txhais li cas?
Txhais ntawm isomorphous . Hais txog crystals muaj tib lub atomic kev npaj.

Binary fission yog dab tsi thiab vim li cas nws tseem ceeb?
Binary fission yog ib daim ntawv ntawm asexual reproduction siv los ntawm cov tswv cuab ntawm domains archaea thiab cov kab mob ntawm lwm yam kab mob. Zoo li mitosis (hauv eukaryotic hlwb), nws ua rau kev faib tawm ntawm cov cell qub los tsim ob lub hlwb uas tuaj yeem rov ua cov txheej txheem
Ib qho piv txwv ntawm ib qho alloy yog dab tsi?
Ib qho piv txwv ntawm cov hlau yog sib xyaw ntawm cov hlau thiab hlau. Ib qho piv txwv ntawm cov hlau yog cov tin hauv qhov sib xyaw ntawm tooj liab thiab tin uas ua rau tooj liab. Lub alloy yog ib qho fusion ntawm ob lossis ntau dua hlau lossis cov hlau uas tsis yog hlau. Ib qho piv txwv ntawm cov hlau yog tooj dag, uas yog tsim los ntawm tooj liab thiab zinc
Dab tsi yog qhov alloy ntawm tin?
Solder yog ib qho alloy ntawm tin thiab txhuas siv los tsim hluav taws xob sib txuas. Terne phaj yog ib qho alloy ntawm tin thiab txhuas siv rau txheej hlau. Qee qhov antique pewter muaj cov tin thiab txhuas, qee zaum ua ke nrog lwm cov hlau. Lwm cov alloys uas muaj tin thiab txhuas muaj nyob, tab sis lawv feem ntau siv qee cov ntsiab lus ntxiv
Dab tsi yog kev siv wrought alloy hauv kev kho hniav?
Piv txwv ntawm kev siv wrought alloys hauv kev kho hniav muaj xws li cov khoom siv los ua cov cuab yeej thiab burs, xov hlau, thiab qee zaus, cov hniav cuav. Hlau thiab stainless hlau yog feem ntau siv wrought alloys thiab yog li tsim nyog ntawm qee qhov kev sib tham kom ntxaws
Qhov noble alloy yog dab tsi?
Noble alloys hauv kev kho hniav. Noble hlau siv rau kev kho hniav castings tseem muaj alloys ntawm kub, palladium, thiab nyiaj (tsis yog ib tug noble hlau), nrog me me ntawm iridium, ruthenium, thiab platinum. Feem ntau yog siv los ua cov thaub qab rau ceramic ci, nrog rau qhov seem siv ua inlays, onlays, thiab unveneered crowns
