7.2   Rotor materials


Developments in the field of steam turbine design would not have been possible without corresponding materials developments. The development of alloys with properties which provide good creep-resistance at high temperature and of other alloys with good mechanical and high fracture toughness has been one area of considerable metallurgical accomplishment.

Also, the ability to produce components for use both at high and low temperatures, having large physical size and uniform material properties which meet rigorous inherent defect acceptance requirements, testifies to the improvements in steel-making techniques.
