Rational Ntxiv ntawm Alloy Elements

 

 

Multicomponent Alloy Design: Txhawm rau kom ua tiav cov txiaj ntsig zoo zog, lub tshuab hluav taws xob sib txuas tuaj yeem tsim tau. Piv txwv li, nyob rau hauv npib tsib xee-raws li superalloys, ntau yam xws li chromium (Cr), molybdenum (Mo), tungsten (W), txhuas (Al), thiab titanium (Ti) ntxiv ib txhij. Chromium yog siv los txhim kho cov tshuaj tiv thaiv antioxidant thiab tiv thaiv corrosion, molybdenum thiab tungsten tuaj yeem ntxiv dag zog rau cov matrix, thiab txhuas thiab titanium ntxiv dag zog rau cov hlau los ntawm kev tsim cov '- Ni₃ (Al, Ti) nag lossis daus theem. Qhov no multicomponent alloy tsim enables npib tsib xee-raws li superalloys kom muaj zog zoo heev thiab antioxidant zog nyob rau hauv high kub thiab muaj peev xwm tiv taus lub hnyav ua hauj lwm tej yam kev mob ntawm siab kub Cheebtsam xws li aero - cav qhov chaw.

 

Kev tswj nruj ntawm cov ntsiab lus impurity

 

Txo cov ntsiab lus ntawm kev puas tsuaj impurity ntsiab: Rau cov khoom siv hlau, cov ntsiab lus ntawm cov teeb meem impurity yuav tsum raug txo kom tsawg li ntau tau. Piv txwv li, hauv kev tsim cov hlau, cov ntsiab lus ntawm sulfur (S) thiab phosphorus (P) raug tswj nruj heev. Sulfur ua ke nrog hlau los tsim ferrous sulfide (FeS), raws li tau hais ua ntej, uas ua rau kub - luv luv tshwm sim. Los ntawm cov txheej txheem refining, xws li cov pa hluav taws xob yooj yim (BOF) lossis hluav taws xob arc rauv (EAF) steel - ua txoj hauv kev, cov ntsiab lus ntawm sulfur tuaj yeem raug txo kom qis qis (piv txwv li, tsawg dua 0.{{ 6}}2%). Phosphorus ua rau qhov txias - luv luv tshwm sim hauv cov hlau, thiab nws cov ntsiab lus tseem yuav tsum tau tswj nruj me ntsis. Feem ntau, cov ntsiab lus phosphorus hauv cov hlau zoo yog tswj tau qis dua 0.02% - 0.04%.

Siv cov txiaj ntsig zoo ntawm cov ntsiab lus tsis huv (yog tias muaj): Qee zaum, qee qhov impurity tej zaum yuav muaj txiaj ntsig zoo ntawm cov ntsiab lus tsawg. Piv txwv li, hauv qee cov qib steel tshwj xeeb, me me ntawm boron (B) lub caij tuaj yeem txhim kho cov tawv tawv ntawm cov hlau. Boron atoms sib sau ua ke ntawm austenite grain ciam teb thiab inhibit qhov nucleation ntawm ferrite ntawm cov ciam teb thaum lub sij hawm quenching txheej txheem, ua rau cov hlau kom tau ib tug sib sib zog nqus hardened txheej tom qab quenching thiab yog li nce lub zog. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv no, cov ntsiab lus ntawm boron yuav tsum tau tswj kom meej, feem ntau nyob rau hauv qhov ntau ntawm 0.0005% - 0.003%.
