## Abstract Carburization of iron was studied at atmospheric pressure over the temperature range 850°C to 1150°C in gaseous mixtures of CO, H~2~, and He. The resistance relaxation method was applied to measure the carburization rates. Experimental results show that for carburization in CO‐He mixtur

## Abstract A numerical model for the carburization of iron in CO‐H~2~‐He mixtures was developed and compared with experimental data over the temperature range of 850°C–1150°C, CO partial pressures from 1% to 12%, and H~2~ partial pressures from 5% to 99%. The reaction mechanism was established on
## Abstract The formation of an α‐Fe layer between cementite and graphite was observed and investigated during metal dusting of iron in CO‐H~2~‐H~2~O gas mixtures at both 600°C and 700°C. The condition to form this phenomenon is determined by the gas composition which depends on temperature. The ir
