Abstract

Measurement results of 92W-5Re-3Ni and 77W-20Re-3Ni sinters produced from powders spheroidized in a plasma jet are presented in the paper. The production process is described, typical microstructures are presented, and the analysis of chemical composition in selected microregions of the samples have been performed. Additionally, a comparison of selected properties of materials produced from powders spheroidized in plasma and from non-modified powders is shown.
