Formation of Nitrous Austenite during Diffusion Saturation of Steel KhA,
Abstract
Nitride austenite produced during nitriding of 38KhA steel is heterogeneous in composition. In the nitriding temperature interval studied (750-1050 degrees C), there are two isostructural solid solutions, one of which is a solid solution of carbon, the other being a solid solution of nitrogen in the face-sintered cubic lattice of the matrix. The maximum saturation of austenite by nitrogen is achieved at 900 degrees C. A homogeneous nitride-carbide austenite is formed in the nitriding modes used only in the 1000-1050 degree C interval. The coefficient of diffusion of nitrogen in the austenite of type 38KhA steel was approximately determined. (Author)
