Abstract:
In order to develop technology for production nickel based superalloys by vacuum precise casting the extensive investigations have been done. Considering that these castings, namely turbine blades, are to be working in hard conditions, it is necessary to fulfill high microstructure criteria and mechanical properties. For accomplishing required quality the casting and solidification parameters should be under control. Complete quantitative and qualitative characterization of blades obtained by vacuum precise casting in ceramic mold was investigated. Present phase identification and measurement of structure parameters have been done because they are relevant for blades behaviour in working conditions. In this way the correlation technology-structure-properties was defined.
