Cov nyhuv ntawm Chemical Composition

 

Alloy Element Cov ntsiab lus thiab kev faib tawm: Alloy cov ntsiab lus hauv cov ntaub ntawv muaj feem cuam tshuam rau kev tawg toughness. Piv txwv li, ib qho dhau los lossis tsis txaus ntawm qee cov ntsiab lus alloy tuaj yeem hloov cov theem ntawm cov khoom. Yog hais tias ib tug tej yam hlau ntsiab yog ntxiv nyob rau hauv ntau, ib tug brittle theem yuav raug tsim. Siv cov hlau ua piv txwv, cov pa roj carbon ntau dhau tuaj yeem tsim cov carbides ntxhib, thiab cov carbides zoo li ua qhov chaw ntawm cov kab nrib pleb thaum cov khoom muaj kev ntxhov siab, txo cov pob txha toughness. Nyob rau tib lub sijhawm, kev faib tsis sib xws ntawm cov ntsiab lus alloy kuj muaj qhov tsis zoo. Thaum cov ntsiab lus hlau nyob hauv cheeb tsam tau ntxiv los yog depleted, nws yuav ua rau cov khoom tsis sib xws ntawm cov khoom siv microstructure, txo cov toughness ntawm cov cheeb tsam hauv zos.

 

Kev pom ntawm Impurity Elements: Cov ntsiab lus impurity yog lwm yam uas ua rau txo cov pob txha toughness. Cov impurities xws li phosphorus thiab sulfur feem ntau yog teeb meem hauv cov ntaub ntawv. Cov phosphorus keeb yuav cais ntawm cov ciam teb nplej, txo cov kev sib raug zoo ntawm cov qoob loo. Thaum cov khoom raug rau sab nraud quab yuam, cov kab nrib pleb yuav tshwm sim ntau dua ntawm cov ciam teb, yog li txo cov pob txha toughness. Cov tshuaj sulfur yuav tsim sulfide inclusions, thiab cov inclusions yog sib npaug rau sab hauv tsis xws luag nyob rau hauv cov khoom, yooj yim ua rau tawg thiab cia lawv mus propagate.

 

Microstructural Factors

 

Grain Size thiab Morphology: Cov qoob loo loj thiab morphology yog qhov tseem ceeb rau kev puas ntsoog toughness. Feem ntau hais lus, coarse nplej yuav txo cov pob txha toughness. Vim hais tias ntxhib - grained cov ntaub ntawv muaj kuj tsawg grain ciam teb, thaum sab nraud quab yuam yog siv, dislocation txav yog ntau dua yuav raug thaiv nyob rau hauv lub grain ciam teb tsawg, ua rau nws nyuaj rau disperse cov kev nyuaj siab concentration los ntawm zawv zawg thiab deformation ntawm grain ciam teb. Ntawm qhov tsis sib xws, cov ntaub ntawv zoo- grained muaj ntau qhov ciam teb, uas tuaj yeem cuam tshuam kev txav mus los thiab cuam tshuam kev ntxhov siab, yog li muaj kev puas tsuaj ntau dua. Tsis tas li ntawd, morphology ntawm cov nplej kuj muaj kev cuam tshuam. Piv txwv li, acicular lossis columnar nplej tuaj yeem ua rau muaj qhov sib txawv ntawm cov kev taw qhia ntawm kev ntxhov siab, thiab piv nrog cov nplej equiaxed, tawg propagation yog feem ntau tshwm sim nyob rau hauv ib qho kev taw qhia.

 

Phase Composition thiab Distribution: Cov theem muaj pes tsawg leeg thiab kev faib tawm hauv cov khoom siv kuj cuam tshuam rau qhov tawg toughness. Yog tias cov theem nkig muaj nyob thiab cov theem nkig no txuas ntxiv los yog muab faib rau hauv lub network hauv matrix, nws yuav muab txoj hauv kev rau kev nthuav tawm tawg. Piv txwv li, nyob rau hauv ib co hlau - matrix composites, yog hais tias lub reinforcing theem yog tsis zoo - bonded rau lub matrix, los yog yog hais tias lub reinforcing theem nws tus kheej yog nkig, thaum lub sab nraud quab yuam yog thov, cov kab nrib pleb tau yooj yim propagate raws lub interface ntawm lub reinforcing theem. lub matrix los yog nyob rau hauv lub nkig reinforcing theem, txo cov pob txha toughness ntawm cov khoom.
