Use induction to melt and cast sixteen different Nickel-Iron alloy samples from powder and shavings for spectroscopic analysis. The samples must be melted in an inert atmosphere to ensure a low loss of nickel and to eliminate any oxidization of the samples, which are required for high fidelity chemical analysis.
• The samples consist of Nickel, Iron, and Copper according to the composition in the table below. The samples were in the form of metal powders or scraps.
Power: 4.5 kW
Temperature: Varies based on the sample
Time: 80-110 secs.
Other: Melting and castings were made under vacuum and inert gas (-0,2bar argon)
