Popis:	Deoxiclation experiments using Ti, Pr and Ti/Pr have been conducted using a Fe-10mass% alloy at 1 600 degrees C. The purpose of the experiments was to study the change of particle size distribution as functions of holding time, difference between the different deoxidation procedures, and amount of deoxiclant added. The Fe-10%Ni alloy was melted in a induction furnace and Ti, Pr or Ti/Pr were added as deoxidants. Samples were taken at different times after the addition of deoxidants. Thereafter, particles from each sample were extracted using electrolytic extraction. These particles where then examined in a SEM and image analyzer. Results show that the peak height of the size distribution decreases and the modal value increases with an increasing holding time. Furthermore, that the number of particles increases with an increase of deoxidant for a given initial oxygen content and holding time. The size distribution in case of the complex deoxidation using Ti followed by Pr deoxidation was also compared with cleoxiclation using only Pr.
