Effect of Heat Treatment on Alloy GH901 Microstructure and Mechanical Properties

  • Published:
Metal Science and Heat Treatment Aims and scope

Processes occurring within heat-resistant alloy GH901 based on the Fe – 43Ni – 12Cr system during hot pressing performed with different rates at 990 – 1140°C are studied. Morphology, grain size, and secondary phase inclusion distribution are determined. Evolution of the alloy microstructure and of mechanical property variation are analyzed after different heat treatment.
