Evaluation of structure characteristics of centrifugally cast alloy based on Ni3Al
Original language description
Ni3Al based alloys were prepared by method of gravity or centrifugal casting on different machines. Part of alloys was prepared by method of vacuum induction casting in various atmospheres. Method of centrifugal casting was verified for this type of alloys on two different machines. Melting was performed in zirconium crucible and the melt was cast into graphite or metallic mould. The samples prepared in this manner had shape of bars, cylinders or tubes. Selected castings were used for determination of structure characteristics. Material structure was investigated in cross and longitudinal sections, phase composition, micro-hardness and material porosity were determined. The alloys have very different contents of gases ? oxygen and nitrogen. Higher contents of air oxygen were determined in all types of alloys melted and cast on air. It follows form results that material is highly susceptible, in contact with air, to absorb air oxygen. The values of micro-hardness in the samples that wer
