Centrifugally cast alloy based on Ni3Al-structure characteristics
Original language description
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.Ni3Albased 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 ontwo different machines. Material structure was investigated in cross and longitudinal sections, phase composition, micro-hardness and material porosity were determined. The values of micro-hardness in the samples that were so far tested do not show anysignificant differences. No substantial influence of micro-hardness occurred in gravity cast samples melted on air, either. This is a favourable finding, since effect of air atmosphere will probably not impair quality of the cast pieces.
