Research
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
