In the 1960s, the Superalloys Division developed the first cast Ni-based superalloy (K417) under the lead of Prof. Changxu Shi. Researchers established vacuum precision casting technology and cast the first hollow blade in China, which made China the second country after the United States that could produce aero-engine blades through a precision casting process. This was a milestone in Chinese superalloys history and steered the R&D of superalloys in China toward rapid development.
Over the past decades, a series of cast and wrought alloys have been developed and widely applied in the aeronautic, astronautic, nautical, energy, and petrochemical fields. Near 200 staff and students (MSc and PhD students) now work in the division, focusing mainly on alloy design and the advanced processing, microstructural characterization, and mechanical behaviors of high-temperature structural materials. The division is well-equipped with investment in casting facilities (vacuum induction melting, vacuum arc remelting, core and shell, directional solidification, etc.) and related analytical and testing equipment.
