Taw qhia
Super alloys muaj peev xwm ua haujlwm ntawm qhov kub thiab txias heev thiab cov neeg kho tshuab kev ntxhov siab, thiab tseem yuav tsum muaj qhov chaw siab ruaj khov.Lawv muaj kev nkag siab zoo thiab oxidation tsis kam, thiab tuaj yeem tsim tau ntau yam duab.Lawv tuaj yeem ua kom muaj zog los ntawm kev daws teeb meem hardening, ua haujlwm hardening, thiab nag lossis daus hardening.
Super alloys muaj ntau lub ntsiab lus hauv ntau qhov sib xyaw ua ke kom ua tiav qhov xav tau.Lawv tau muab faib ua peb pawg xws li cobalt-based, nickel-based, thiab hlau-raws li alloys.
Incoloy(r) alloy 825 yog ib qho austenitic nickel-hlau-chromium alloy uas tau ntxiv nrog rau lwm cov khoom siv hlau txhawm rau txhim kho nws cov khoom siv tshuaj tiv thaiv corrosion.Cov ntaub ntawv hauv qab no yuav muab cov ntsiab lus ntxiv txog Incoloy(r) alloy 825.
