Slitiny na bázi Ni3Al - mechanické vlastnosti v tlaku

Abstract

This Bachelor thesis is focused on nickel alloys, mainly on group of intermetallic alloys based on Ni3Al phase. In the work there is described a basic distribution of nickel based alloys and it shows properties of intermetallic Ni3Al based alloys. Usage of these alloys still expands, mostly for application, where high temperature corrosion resistance, high tensile or compressive strength and high temperature creep resistance is needed. Mechanical properties of these alloys can also be strengthened by directional solidification, which is described in this thesis. Practical part of this work is focused on influence of directional solidification on mechanical properties of intermetallic alloys in compression. For comparison there are as-cast and directed samples.
