SUMMARY

The discussion focuses on the encapsulation of samples for heat treatment at 600°C to prevent oxidation. The user is considering quartz glass but finds it too expensive due to the number of samples. They seek recommendations for specific elemental foils that are resistant to oxidation at high temperatures and can be used as a cost-effective alternative. Incoloy, a metal alloy rated to 1400°F, is mentioned as a potential option.

PREREQUISITES
  • Understanding of heat treatment processes and temperature effects on materials.
  • Knowledge of oxidation resistance in metals and alloys.
  • Familiarity with encapsulation techniques for high-temperature applications.
  • Basic awareness of material costs and selection criteria for industrial applications.
NEXT STEPS
  • Research the oxidation resistance of Incoloy and other high-temperature alloys.
  • Investigate the properties and costs of various elemental foils suitable for encapsulation.
  • Explore alternative encapsulation methods that balance cost and effectiveness.
  • Learn about the thermal properties of quartz glass and its applications in heat treatment.
USEFUL FOR

Materials scientists, metallurgists, and engineers involved in high-temperature processing and oxidation prevention strategies.

HI

I want to heat treat my samples (dimensions: 4:4:2 mm3) at about 600 C, for different times from 30 min to 3 days. Since my alloy is highly sensitive to high temperature oxidation, I have to encapsulate them so as to prevent them from being oxidized.

I was thinking of encapsulating them in quartz glass. However, this method is very expensive, as I have too many samples.

One method is to roll the samples in some layers of foil of a specific element. Does anyone know an element, foils of which are resistant to oxidation at my temperatures and times? Please mention every element or alloy that works, whether cheap or expensive.

Thank You very much in advance
