Nickel-based superalloys are distinguished from other materials by their excellent mechanical and physical properties. As they are used at high temperatures and pressures, as well as in aggressive environments, their characteristics need constant improvement. An adequate choice of their chemical composition and the heat-treatment regime contributes to the improvement of the chemical, physical and mechanical properties of these nickel-based superalloy materials. During the heat treatments of the
superalloys Nimonic 263 and Hastelloy S some changes in their microstructures were observed. In this paper the changes in the microstructures after various regimes of the heat treatment were analysed on the fractured surfaces. The fractured surfaces were observed using light microscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray spectrometry (EDS).
Superzlitine na osnovi niklja se razlikujejo od drugih materialov zaradi svojih odličnih mehanskih in fizikalnih lastnosti. Ker se
jih uporablja pri visokih temperaturah in tlakih ter v agresivnem okolju, je potrebno stalno izboljševati njihove lastnosti.
Primerna izbira kemijske sestave in načina toplotne obdelave prispevata k izbolj{anju kemijskih, fizikalnih in mehanskih
lastnosti superzlitine na osnovi niklja. Med toplotno obdelavo superzlitine Nimonic 263 in Hastelloy S se opazijo spremembe v
mikrostrukturi. V tem članku so analizirane spremembe mikrostrukture na prelomnih površinah po različnih toplotnih
obdelavah. Površina prelomov je bila opazovana s svetlobno mikroskopijo, vrstično elektronsko mikroskopijo (SEM) in rentgensko disperzijsko spektroskopijo (EDS).
