Hlau alloy 718, tseem hu ua Inconel 718, yog ib qho nrov nickel-based alloy.2.4668 Inconel 718 phajfeem ntau yog siv rau hauv kev ua haujlwm siab, xws li roj turbines, aerospace structures, thiab foob pob hluav taws cav. Ib qho tseem ceeb tshaj plaws uas yuav tsum tau xav txog thaum ua hauj lwm nrog no N07718 alloy yog nws cov ntaub ntawv annealed.
Ni Alloy 718 Annealing yog dab tsi?
Annealing yog txheej txheem ntawm cua sov cov khoom mus rau qhov kub thiab txias, tuav nws ntawm qhov kub ntawm lub sijhawm, thiab tom qab ntawd maj mam txias. Cov txheej txheem no yog siv los txhim kho cov cuab yeej ntawm cov khoom siv, xws li nws cov ductility, toughness, thiab lub zog. Nyob rau hauv cov ntaub ntawv ntawmHlau alloy 718, annealing yog qhov tseem ceeb tshwj xeeb vim tias nws tuaj yeem txhim kho cov khoom siv tiv thaiv kev qaug zog, kev ntxhov siab-corrosion tawg, thiab lwm yam kev puas tsuaj.
Cov ntaub ntawv annealed ntawmNi 718 inconel daim ntawvnyob ntawm ntau yam, suav nrog qhov kub thiab txias, qhov txias txias, thiab lub sijhawm ntawm lub voj voog annealing. Feem ntau, ib qho annealed inconel 718 kub ntawm ib ncig ntawm 980 degree yog pom zoo, thiab cov khoom yuav tsum tau tuav ntawm qhov kub thiab txias rau tsawg kawg ib teev. Tom qab ntawd, cov khoomInconel alloy 718yuav tsum tau txias maj mam nyob rau hauv ib puag ncig tswj kom tsis txhob muaj qhov kub thiab txias hloov uas tuaj yeem ua rau thermal shock.
