摘要
The kinetics and the influence of time on granular manganese nitriding were studied by means of a vacuum resistance furnace,X-ray diffraction technique,and LECO TC-436 oxygen/nitrogen determinator.The longer the nitriding time,the more the nitrogen pickup.Except for a trace of oxide MnO that developed,the metal manganese could thoroughly be nitrided to form Mn4N and a little ζ-phase（the stoichiometric components as Mn2N）with the nitriding time lasting.A kinetic model is developed to reveal the nitriding situation and agrees well with the experimental results.
