Abstract
Purpose: The Ni-Ta-Al alloys with high carbon content, strengthened by intermetallic phases, designed for application in high temperatures is presented in the hereby paper. The proposed chemical composition and the results of microstructure investigations as well as hardness in as-cast and after heat treatment condition - are given. Design/methodology/approach: A test melt of a mass of approximately 1 kg was made in a vacuum furnace, and cast into a ceramic mould. The microstructure of the investigated material was examined by a light microscope Axiovert 200 MAT and the scanning electron microscope FIB Zeiss NEON 40EsB CrossBeam. The heat treatment was performed using the DT 1000 dilatometer made by Adamel Lhomargy, the French Company. Findings: The main constituents of the microstructure of the Ni-Ta-Al investigated alloy are: the y phase (matrix), the y' phase (fine globular precipitates) and as well as primary Ta carbides of MC type and graphite. Primary carbides of irregular shapes are uniformly distributed and not forming agglomerates. Research limitations/implications: Identification of microstructure components on Ni-Ta-Al with high carbon content materials strengthened by intermetallic phases. Practical implications: The new model alloy which allows to design a new material for high temperatures applications. Originality/value: The new chemical compositions and microstructure of high temperature application Ni based materials with high carbon content. Additionally the new alloy, except high carbon volume fraction, is strengthened by intermetallic phases.
