High Temperature Materials Design Team

The heat-resistant materials design team is joined with the “Heat-resistant materials design” joint course at the University of Tokyo graduate school of Frontier Sciences (a professor: Yoko Mitarai, a lecturer: Tetsuya Matsunaga)

Specialized Research Field

1.Design of high-temperature materials

High-temperature materials are used in jet engines of airplane and gas turbines in power plants. We focus on Ti alloys used in compressors of jet engine and high-temperature shape memory alloys which are expected to be used as high-temperature devices. We are attempting to improve high-temperature mechanical properties by microstructure control using forging, rolling, and heat treatments. We also attempt to develop new materials with high performance using 3D additive manufacturing which has been attractive as new processing. In addition, high-entropy alloys which are expected as new generation structural materials will be applied for high-temperature materials and shape memory alloys. The detailed research topics are followings

(1)    Development of high-temperature Ti alloys for jet engines with valance of creep and fatigue properties.

(2)    Development of high-temperature materials using 3D additive manufacturing

(3)    Understanding of high-temperature deformation of high-entropy alloys

Understanding of high-temperature shape memory effect and design of new high-temperature shape memory alloys


2.Deformation mechanism

Failure of materials around our lives such as car, airplane, implant and so on is related to quality of life. Because these materials are designed for long life, it is important to maintain their soundness during the operating time. Our laboratory focuses on improvement of mechanical properties on metals by solid solution, precipitates etc. to protect people’s lives from the incident.

(1) Effect of a solid solution element on high temperature creep in heat resistant materials

(2) Development of new heat resistant materials for high temperature uses

(3) Infrared thermography for quick evaluation of mechanical property
