The present work deals with investigation of the powder stainless steel Fe-16Cr-2Ni-Mo-Mn, obtained by mechanical alloying and the study of samples obtained from mechanically alloyed powders by spark plasma sintering. The effect of treatment time on the doping process was shown. The influence of sintering conditions on the microstructure and mechanical properties of the samples was revealed.

The effect of processing conditions on microstructure and mechanical properties of Fe-Al-Si powders was studied by means of scanning electron microscopy, X-ray diffraction and nanoindentation. Fe-Al-Si alloy powder was prepared from pure elemental powders by mechanical alloying. Microstructure and mechanical properties of powders were characterized after various durations of mechanical alloying. Special sample preparation technique was developed allowing to characterize the properties of individual powder particles after each step of processing in a planetary ball mill. This step-by-step characterization allowed to find the optimum conditions for subsequent spark plasma sintering.
