In order to study the feasibility of in-situ self-generating aluminum nitride and the effect of experimental conditions such as doping elements and temperature on the nitriding process, direct nitriding experiments were carried out on the alloys with different compositions under 1000 ℃ high purity nitrogen atmosphere. By means of chemical composition analysis and X-ray diffraction analysis, the possibility of self-generated AIN from in situ reaction was analyzed from the thermodynamic point of view. Including the doping elements Mg, Si thermodynamic behavior, as well as aluminum alloy melt nitriding reaction process analysis. Based on the experiment of thermo-gravimetric thermogravimetry, the effect of doping elements and nitriding temperature on the nitridation reaction rate was discussed.
