Abstract

5th generation single crystal superalloys

Castability

Creep

Oxidation

Thermo mechanical fatigue

A 5th generation single crystal (SC) superalloy TMS-196 with improved microstructural stability and environmental properties was designed with using NIMS Alloy Design Program and evaluated experimentally. It was found that TMS-196 has a very stable microstructure even after 1000h creep at 1100°C and also very well balanced creep, TMF and environmental properties. TMS-196 also had excellent SC castability; sound cooling blades of up to 300mm long were successfully cast.
