Abstract [en]

The process of internal oxidation and reduction of internal oxides is of interest in several powder metallurgy processes. In powder annealing the surface oxides, as well as some internal oxides, are reduced. The reduction of internal oxides depends on the oxygen mobility and the oxide stability at high temperature, which can be simulated by computational tools such as Dictra and Thermo-Calc. Internal oxidation can also occur in other processes, like capsule free HIP or carburisation with minor oxygen content but still enough to cause internal oxidation. Due to the difficulty in evaluating the oxygen mobility by experimental methods one can consider internal oxidation experiments that are the product of both the solubility and diffusivity. This has been done in this work for several different alloying systems; Fe-Cr, Fe-Al, and Fe-Mn. With this approach it is possible to find the most reliable set of thermodynamic and kinetic data to be used in simulations for powder metallurgical processes
