Effect of solidification rate of the structure of alloys of the system Fe-W
Authors:A P Gulyaev  O D Sidorova  T P Moskvina
Abstract:Conclusion In alloy Fe-42% W atomized with a cooling rate during solidification within the limits from 5·103 to 1·105°C/sec with the maximum cooling rate (not less than 105°C/sec) precipitation of mgr-phase (Fe7W6) from the liquid melt is suppressed. In granules of alloy obtained with a high solidification rate it is possible to achieve total dissolution of tungsten in solid solution (42%). Subsequent heating causes precipitation of mgr-phase in dispersed form.I. P. Bardin Central Scientific-Research Institute of Ferrous Metallurgy (TsNIIChERMET) Moscow.
