Rotating furnace
This rotating furnace has been used to observe the difference in ferrite phase fraction in steel during isothermal holds by in-situ XRD. The rotation capability of the furnace can be used in order to average grains in diffracting condition and thus obtain clean powder pattern data.
Ferrite phase fractions and kinectics
Benrabah et al. observed the difference in ferrite phase fraction in steel, where samples had a gradient in composition, during isothermal holds at different temperatures (between 700 °C and 800 °C) by in-situ XRD. This approach enabled the screening of phase transformation kinetics for a wide range of steel compositions within one in-situ heat treatment (high-throughput) experiment. The rotation capability of the furnace was especially interesting in order to average grains in diffracting condition and thus obtain clean powder pattern data.
Experiments were performed at the Swedish Materials Science beamline, P21.2 branch.
