Zoo heev High -Temperature Strength thiab Creep Resistance
MAR-M 509 muaj lub zog tensile zoo tshaj plaws, lub zog tawm los, thiab nkag siab tsis kam ntawm qhov kub thiab txias vim yog cov kua qaub ntxiv zog (tungsten) hauv cov cobalt matrix thiab dispersion ntxiv dag zog los ntawm carbides (MC thiab M₂₃C₆ hom). Lub alloy lub sij hawm ntev -lub sij hawm lub zog ntawm 900℃yog 40-50 MPa siab tshaj qhov piv ntawm alloy X-40, nrog ib tug txhim kho kub muaj peev xwm ntawm 40-50℃. Nws yog qhov tsim nyog rau cov khoom nyob ruaj ruaj xws li turbine qhia vanes thiab cov lus qhia uas raug rau lub sijhawm ntev ntawm kev kub ntxhov.
Zoo Oxidation thiab Kub Corrosion Resistance
The high chromium content (approximately 23%) promotes the formation of a dense and stable Cr₂O₃ oxide film on the alloy surface, effectively preventing matrix oxidation in high-temperature oxidizing atmospheres. Tsis tas li ntawd, qhov sib ntxiv ntawm cov ntsiab lus xws li tantalum thiab tungsten ntxiv txhim khu lub alloy lub tshav kub corrosion kuj. Lub cobalt matrix muaj kev tiv thaiv zoo rau cov xov xwm kub corrosion xws li sulfur thiab vanadium, ua rau nws tshwj xeeb tshaj yog haum rau siab - qhov kub thiab txias ib puag ncig hauv cov tshuab dav hlau thiab cov roj turbines.
Zoo Microstructural Stability thiab Thermal Shock Resistance
MAR-M 509 tuav cov qauv carbide ruaj khov thaum lub sij hawm ntev - lub sij hawm siab - kub qhov kev pab cuam thiab ua pov thawj zoo thermal shock resistance. Txawm tias nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias, nws cov khoom siv kho tshuab tseem nyob ruaj khov, ua rau nws haum rau kub -kawg cov khoom hauv cov tshuab dav hlau thiab cov roj turbines uas muaj kev pib ntau zaus - nce thiab kaw lub voj voog.
Casting thiab Machining Properties
MAR-M 509 feem ntau yog tsim los siv cov txheej txheem precision casting (kev nqis peev casting) cov txheej txheem, uas yog tsim rau kev tsim cov complex-zoo li kub- kawg cov khoom xws li turbine qhia vanes thiab cov lus qhia. Lub alloy muaj feem ntau siv tau machining zog thiab pom zoo kom machined nrog nyuaj hlau txiav cov cuab yeej. Nws txoj kev weldability yog txwv thiab yuav tsum tau siv cov txheej txheem tshwj xeeb.
