Heat Treatment (1)
- From:
- Sample Conditions
- Date:
- 1/27/2022
- Furnace:
- Lindberg tube furnace
- Temperature [C]:
- 650
- Soak Duration [hr]:
- 4
- Atmosphere:
- Air
- Cooling:
- Furnace cooling
- Comments:
- Thought Ar was being pumped into the chamber during HT but later found that it was not. Assuming that the sample was treated in air with no Ar present. The furnace temperature read out is inacurrate so in order to achieve a true temperature of 650 C the furnace needs to be set to approximately 680 C. The furnace takes approximately 45 mins to reach operating temperature
