Superalloys are state-of-the-art metals used m engineering. One family of superalloys are known as Inconel alloys that are based on nickel and chromium. They are used primarily for their extreme corrosion and oxidation resistance even at high temperatures. This resistance is the reason why companies like SpaceX, Tesla, Ford, Rocketdyne and many others use them in highly corrosive high temperature applications. For example, SpaceX actually 3D prints rocket engine manifolds using Inconel and direct metal laser sintering from powder metal precursors! Tesla achieves \"Ludicrous Mode\" (0 to 60 in 2.8 seconds!) by using this alloy in the battery container which allows 1500 A of current instead of a paltry 1300 A. Look up Inconel 690 alloy here and determine what the atomic percent of iron in this alloy is.

Solution

0.164 * N

55

atomic percentage of iron = ( number of atoms in Fe / Total number of atoms in the alloy ) * 100

at% of iron = ( 0.164 * N / ( 1.770663 N ) *100

at % of iron = 9.262 %
