High Performance Alloys Group
Welcome to High Performance Alloys Group. This group is involved in the research of various heat-resistant alloys including Fe-base austenitic alloys and Ni-base superalloys haing superior heat resistance and environmental resistant for improving thermal efficiency and cutting CO2 emission in power generation and aero-space engine. We concentrate on developing alloys and their coating system with low cost and high performance by new concepts, alloy design systems, and the control of phase interface and grain boundary, and evaluating the mechanical properties such as creep and fatigue.
Specialized Research Field
1. Development of new high temperature alloys
New kinds of Ni-Co-base forging superalloys with the world's highest thermal stability have been developed by the innovative concept of combining the characters of two kinds of ɣ/ɣ´ two-phase alloys, Ni-base and Co-base superalloys (Fig. 2).
A new kind of strong DS TiAl alloys processed by new mold materials and the control of the misfit between lamella interfaces are under developed for making blade in the advanced aero-engine (Fig. 3).
