Vim li cas superalloys feem ntau siv?
Superalloys los yog high-kev ua tau zoo alloys yog alloys uas muaj zoo heev mechanical zog thiab creep kuj nyob rau hauv siab kub, zoo nto stability, thiab kuj mus corrosion thiab oxidation. Lawv feem ntau muaj austenite-centered cubic crystal qauv thiab muaj npib tsib xee, cobalt lossis npib tsib xee-hlau ua lub hauv paus alloying. Txoj kev loj hlob ntawm superalloys tau tsav feem ntau los ntawm aerospace thiab fais fab kev lag luam.
Corrosion-resistant superalloys yog dav siv nyob rau hauv huab ib puag ncig uas zoo heev tshav kub thiab corrosion kuj tseem ceeb heev rau kev ncaj ncees ntawm cov khoom kawg. Cov alloys kub kub no tau siv dav hauv kev ua tshuaj lom neeg thiab petrochemical, fais fab nroj tsuag, thiab kev lag luam roj thiab roj.
Ntau cov nickel-based superalloys muaj cov ntsiab lus alloying, suav nrog chromium (Cr), aluminium (Al), titanium (Ti), molybdenum (Mo), tungsten (W), niobium (Nb), tantalum (Ta), thiab cobalt (Limited). tuam txhab).
Superalloys, tseem hu ua high-kev ua tau zoo alloys, tau dhau los ua cov hlau xaiv rau corrosion kuj thiab versatility.

High Temperature Alloy Trivia
Lub sij hawm "superalloy" yog thawj zaug siv tsis ntev tom qab Tsov Rog Ntiaj Teb Zaum II los piav txog ib pab pawg ntawm cov alloys tsim rau turbochargers thiab aircraft turbine xyaw uas yuav tsum tau ua haujlwm siab ntawm qhov kub thiab txias.
