Dab tsi yog kev siv cov nickel puag superalloys?
Nickel puag superalloys feem ntau yog siv rau cov qauv ua haujlwm ntawm 950 ~ 1050 degree hauv aerospace teb, xws li cov hniav ua haujlwm, turbine disks, combustion chambers, thiab lwm yam ntawm aeroengines. Yog li ntawd, txoj kev kawm ntawm nickel puag superalloys yog qhov tseem ceeb heev rau kev txhim kho ntawm Tuam Tshoj txoj kev lag luam aerospace. Nickel puag superalloy yog superalloy nrog npib tsib xee raws li matrix (cov ntsiab lus feem ntau yog ntau tshaj 50 feem pua), siab zog, zoo oxidation kuj thiab roj corrosion kuj nyob rau hauv thaj tsam ntawm 650 ~ 1000 degree. Nws yog tsim los ntawm Cr20Ni80 alloy. Txhawm rau ua kom tau raws li qhov xav tau ntawm qhov kub thiab txias thermal zog (siab kub lub zog, creep tsis kam, siab kub qaug zog) ntawm li 1000 degree thiab oxidation kuj thiab corrosion kuj nyob rau hauv nruab nrab roj, ib tug loj tus naj npawb ntawm ntxiv dag zog lub ntsiab, xws li W, Mo , Ti, Al, Nb, Co, yog ntxiv los xyuas kom meej nws cov kev ua tau zoo ntawm qhov kub thiab txias.
