Slitiny na bázi Ni3Al v usměrněném stavu

Abstract

The diploma thesis focuses on the modification of Ni3Al alloy. The theoretical section provides an overview of nickel alloys, possibilities of processing, use of Ni3Al alloys. The practical part describes the preparation and subsequent evaluation of Ni3Al alloys. For modification of the alloy was used directional solidification by Bridgman method. Experimental alloys are different in content of aluminium and speed of directional solidification. On the samples of the modified alloy was determined porosity, microhardness and share of network.
