Dab tsi yog ib tug nickel-based supalloy?

1. Dab tsi yog ib tus nickel-based supalloy?

2. Dab tsi yog qhov tsis zoo ntawm Nickel raws Superalloys?

Kev kub ntxhov heev: tswj lub zog thiab sab nrauv kev ncaj ncees hauv cov pa hluav taws kub, tseem ceeb rau cov tshuab hluav taws xob lossis kev siv hluav taws xob.

Corrosion resistance: chromium cov ntaub ntawv ib txheej oxide txheej, ua rau lawv haum rau cov tubrog nkoj, tshuaj lom neeg, thiab salwater daim ntawv thov.

Creep & nkees tsis kam: tiv thaiv qeeb deformation nyob rau hauv concitor tsis tu ncua thiab cyclic thauj khoom, zoo li turbine discs .

Versatility hauv kev ua: tuaj yeem muab pov, wrought, lossis tsim los ntawm hmoov metallurgy kom haum txoj kev tsim qauv (E} {{{{3}

Weldability: ntau cov qib (e {{{{{{} g.}}}}
