Strukturní charakteristiky žáropevných niklových slitin používaných v leteckém průmyslu

Abstract

This bachelor´s thesis is focused on heat-resisting nickel alloys, also called superalloys, due to their specific properties they are applied in the aerospace industry. It includes primary description these alloys including degradation processes to their microstructural analysis. The thesis contains experimental part, where alloys MAR – M247, in the state after casting, is examined. For this alloy was performed structural phase analysis by scanning elektron microscope JEOL JSM-6490LV with the x-ray microanalyser Oxford Inca x-act. The experiment is concentrated on the structural characteristics of this alloy.
