A model for the kinetics of mechanically assisted gas–solid reactions

This paper proposes a phenomenological model for the kinetics of mechanically induced gas–solid reactions, based on a thermal analogy and supported by the isokinetic character shown by the absorption curves when the specific energy dose is considered. In addition, the rate constant for mechanically...

Description
Summary:This paper proposes a phenomenological model for the kinetics of mechanically induced gas–solid reactions, based on a thermal analogy and supported by the isokinetic character shown by the absorption curves when the specific energy dose is considered. In addition, the rate constant for mechanically assisted nitriding of IVb metals is found to scale with the milling intensity.
