Abstract
Metallographic analyses and surface Mössbauer measurements were carried out on high purity iron borided in a mild boronizing medium. It was found that, irrespective of the preliminary iron treatment such as annealing, carburizing or cold rolling, only a fraction of the exposed surface reacts with boron at 1000° C. The stratified arrangement and the average thicknesses of the different reaction products within the iron boride isles were determined. These results, as compared with those previously obtained for borided Armco iron, allowed the hypothesis of a mechanism for the thermal growth of iron borides.
