Carburization thermomagnetic analysis

Magnetization Resulting from Carburization. Thermomagnetic analysis (TMA) identified magnetite as the only ferromagnetic phase in the unreduced catalyst, and iron in the reduced samples. TMA measurements were made after isothermal carburization and after temperature-...
