Environmental Factors (Cub, Corrosive Media)

Txoj Cai: Kub muaj feem cuam tshuam rau kev qaug zog ntawm cov hlau. Nyob rau hauv ib puag ncig kub kub, atomic kev ua haujlwm ntawm hlau yog txhim kho, dislocation txav tau yooj yim dua, cov khoom siv lub zog thiab hardness txo, thiab qaug zog tawg yog feem ntau yuav pib thiab nthuav tawm. Corrosive media kuj tuaj yeem ua rau corrosion qaug zog hauv cov hlau. Thaum cov hlau nto los rau hauv kev sib cuag nrog lub nruab nrab corrosive, cov tshuaj tiv thaiv tshwm sim, tsim cov kev tsis xws li corrosion pits. Cov teeb meem no tuaj yeem dhau los ua kev ntxhov siab - qhov chaw concentration thiab ua kom qaug zog tsis ua haujlwm. Piv txwv li, nyob rau hauv cov qauv hlau nyob rau hauv ib puag ncig marine (xws li cov roj av sab nrauv), kev sib xyaw ua ke ntawm seawater corrosion thiab alternating stress los ntawm nthwv dej tuaj yeem txo qhov qaug zog lub neej ntawm cov hlau.

Application Scenarios thiab Cases: Hauv kev lag luam tshuaj, ntau yam khoom siv (xws li reactors, pipelines, thiab lwm yam) yuav tsum tau ua haujlwm hauv qhov kub thiab txias thiab corrosive - nruab nrab ib puag ncig. Rau cov hlau siv hauv cov khoom siv no, kev sib xyaw ua ke ntawm qhov kub thiab txias ntawm kev ua haujlwm qaug zog yuav tsum tau xav txog. Piv txwv li, nyob rau hauv lub reactor uas muaj ib tug acidic tov, cov hlau ntawm lub reactor lub cev tsis tsuas yog yuav tsum tau dais lub alternating kev nyuaj siab generated los ntawm lub internal stirring ntaus ntawv tab sis kuj yuav tsum tau tiv thaiv corrosion ntawm acidic tov. Txhawm rau txhim kho kev ua haujlwm qaug zog, cov hlau tsis xeb-resistant alloy steel yuav raug siv, thiab cov nplaim yuav raug kho nrog cov tshuaj tiv thaiv corrosion.

 

 

 

Chemical Composition thiab impurity Cov ntsiab lus ntawm cov khoom

Txoj Cai: Cov tshuaj muaj pes tsawg leeg ntawm cov hlau (xws li cov khoom xws li carbon, manganese, chromium, nickel, thiab lwm yam) tuaj yeem cuam tshuam rau nws cov microstructure thiab cov khoom. Piv txwv li, nce cov ntsiab lus carbon tuaj yeem txhim kho lub zog ntawm cov hlau, tab sis nws kuj tseem tuaj yeem txo cov tawv nqaij, yog li cuam tshuam rau kev ua haujlwm qaug zog. Cov impurity ntau dhau (xws li sulfur, phosphorus, thiab lwm yam) cov ntsiab lus tuaj yeem ua rau cov hlau tsis huv thiab ua rau muaj qhov tsis xws luag xws li suav nrog. Cov teeb meem no tuaj yeem dhau los ua cov ntsiab lus pib ntawm kev qaug zog tawg. Piv txwv li, thaum sulfur cov ntsiab lus nyob rau hauv hlau yog siab, sulfide inclusions yog tsim. Nyob rau hauv qhov kev txiav txim ntawm alternating kev nyuaj siab, kev nyuaj siab concentration yog yooj yim generated nyob ib ncig ntawm cov inclusions, ua rau qaug zog tawg.

Application Scenarios thiab Cases: Hauv kev tsim cov hlau ua haujlwm siab, kev tswj xyuas nruj ntawm cov tshuaj muaj pes tsawg leeg thiab cov ntsiab lus impurity yog ib qho tseem ceeb rau kev txhim kho kev qaug zog. Piv txwv li, nyob rau hauv aerospace - siv hlau, cov ntsiab lus yuav tsum tau rau cov teeb meem impurities xws li sulfur thiab phosphorus yog tsawg heev (feem ntau tsawg tshaj li 0.01%). Nyob rau tib lub sijhawm, cov ntsiab lus alloy (xws li chromium thiab npib tsib xee) tau raug ntxiv los ua kom zoo dua microstructure thiab txhim kho cov kev ua haujlwm ntawm cov hlau kom ua tau raws li qhov xav tau ntawm kev ntseeg siab ntawm cov qauv dav hlau nyob rau hauv txoj kev dav dav.
