Ntxiv ntawm Alloy Elements: Ntxiv cov ntsiab lus alloy rau cov ntaub ntawv yog ib txoj hauv kev tseem ceeb los hloov lawv lub zog. Piv txwv li, cov khoom xws li chromium (Cr), npib tsib xee (Ni), thiab molybdenum (Mo) ntxiv rau cov hlau. Chromium tuaj yeem ua rau cov tawv tawv thiab hnav tsis kam ntawm cov hlau, thiab tib lub sijhawm txhim kho nws cov khoom antioxidant. Nickel tuaj yeem txhim kho qhov toughness thiab corrosion tsis kam ntawm hlau, thiab tuaj yeem tiv thaiv cov hlau los ntawm embrittlement nyob rau hauv ib puag ncig qis. Molybdenum tuaj yeem ua kom zoo dua cov nplej thiab ua kom lub zog ntawm cov hlau los ntawm cov nplej ciam teb ntxiv dag zog. Siv cov hlau tsis muaj hlau ua piv txwv, nws muaj ntau cov chromium thiab npib tsib xee. Qhov kev sib xyaw ua ke no ua rau cov hlau tsis zoo tsis tsuas yog muaj kev tiv thaiv corrosion zoo xwb tab sis kuj muaj lub zog siab, ua rau nws tuaj yeem tiv taus qee yam khoom siv.

 

Kev cuam tshuam ntawm Impurity Elements: Cov ntsiab lus impurity hauv cov ntaub ntawv tseem muaj feem cuam tshuam rau lub zog. Piv txwv li, nyob rau hauv cov ntaub ntawv hlau, impurity hais xws li oxygen thiab sulfur yuav txo tau lub zog ntawm cov khoom. Sulfur yuav ua ke nrog hlau hauv hlau los ua ferrous sulfide (FeS). Lub melting point ntawm ferrous sulfide kuj tsawg. Thaum lub sij hawm kub ua hauj lwm txheej txheem, nws yuav tsim ib tug eutectic nrog ib tug tsawg melting point thiab yaj nyob rau hauv lub grain ciam teb, ua rau lub kub shortness tshwm sim ntawm cov hlau thaum kub ua hauj lwm, uas zoo heev txo lub zog thiab kev ua tau zoo ntawm cov khoom. Hauv qee cov khoom siv semiconductor, cov ntsiab lus thiab hom impurity ntsiab yuav hloov lawv cov khoom hluav taws xob, thiab tom qab ntawd cuam tshuam ncaj qha rau lub zog ntawm cov khoom siv hauv qee qhov kev thov tshwj xeeb.

Microstructural Defects

 

Ncua tseg thiab Interstitial Atoms: Vacancies hais txog qhov tsis muaj atoms hauv cov qauv siv lead ua, thiab cov atom interstitial yog cov nyob rau hauv cov haujlwm interstitial ntawm cov lattice. Lawv lub neej yuav ua rau lub zos lattice distortion. Ncua tseg thiab interstitial atoms yuav ua rau muaj kev tiv thaiv rau kev txav ntawm dislocations, yog li cuam tshuam rau lub zog ntawm cov khoom. Piv txwv li, nyob rau hauv ib tug hlau siv lead ua, lub lattice nyob ib ncig ntawm lub interstitial atoms yuav stretched. Thaum dislocations tsiv mus rau cov cheeb tsam no, lawv yuav tsum tau kov yeej ntau dua, uas ua rau kom lub zog ntawm cov khoom. Txawm li cas los xij, yog tias muaj ntau qhov chaw ua haujlwm thiab cov atoms interstitial, nws yuav ua rau txo qis ntawm cov khoom siv vim tias lawv yuav dhau los ua qhov chaw ntawm cov kab nrib pleb, ua rau cov khoom tawg yooj yim dua thaum raug quab yuam.

 

Dislocation Ceev: Dhau li ntawm kev cuam tshuam ntawm kev sib cais ntawm cov ciam teb ntawm lub zog, qhov sib txawv ntom ntom hauv cov khoom kuj yog qhov tseem ceeb. Qhov siab dua qhov dislocation ceev, qhov muaj zog ntawm kev sib cuam tshuam ntawm dislocations. Thaum dislocations sib tshuam nrog ib leeg, cov txheej txheem nyuaj xws li jogs yuav raug tsim, thiab cov qauv no yuav cuam tshuam qhov kev txav mus ntxiv ntawm kev txav mus los, yog li ua kom lub zog ntawm cov khoom. Piv txwv li, los ntawm kev ua haujlwm txias deformation, dislocation ceev ntawm cov khoom siv hlau tuaj yeem nce ntxiv. Piv txwv li, thaum tooj liab yog txias-dov, qhov dislocation ceev tuaj yeem nce los ntawm qhov qub qis qis los ntawm ob peb zaug lossis txawm kaum ob zaug, ua rau muaj zog ntawm tooj liab, tab sis tib lub sij hawm txo nws cov toughness.
