| description |
Rene 142 nickel-based superalloys produced by directional solidification
technique with columnar grain widely used for turbine blades of aircraft engines.
Columnar grain structures are strengthened by carbide and gamma prime (?????)
phases, which is distributed at grain boundary and intergrain.
In this research, Rene 142 has been solution heat treated at 1250°C with
60 minutes holding time, and cooled by air cooling and furnace cooling.
Composition and type of carbide are obtained by characterization of EDS
(Energy Dispersive Spectroscopy) with mapping and point method.
In conclusion, type of carbide in this material is MC carbide, which are
TaC and HfC. MC type carbide relatively stable and there is a possibility to
decomposed into M23C6 carbide. At solution heat treatment with fast cooling,
dendrite structures are exist, and with slow cooling, dendrite structures are lost
because of element segregation. |
