Outline of Research at the Start

本研究計画では、超音波反射率の界面敏感性に着目し、これを指標とした新たな超音波サーモメトリを創成する。具体的には、非定常加熱状態の材料界面の反射率を測定し、これを指標としたマルチステップ逆解析を実施することで界面の不安定性の影響を軽減し、実用レベルの高精度温度プロファイリングを実現する(死の谷の克服!)。同時に、上記逆解析を駆使することで界面近傍の被加工材料の特性評価(弾性率、密度、粘性)とその挙動(被加工材の接触状態、剥離状態、反応層の有無など)の定量評価が可能となるので、これを効果的に活用したロバストかつ高機能な高温モニタリング手法の開発を目指す。

Outline of Final Research Achievements

This work aims to create a new ultrasonic method for measuring the temperature profile and material properties of the inside, surface and interface of heated materials. First, a robust ultrasonic measurement system suitable for high temperature fields is constructed and a new temperature profiling method for the surface and the inside of a heated material is then developed. Next, a multi-channel ultrasonic measurement system for high temperatures is newly developed. The system is applied to real-time monitoring of the casting process installed as a feasibility experiment at a laboratory and its usefulness is then demonstrated. In addition, a backside condition monitoring method that utilizes the reflectance of thick plate materials is proposed and its effectiveness is also verified. Thus, the ultrasonic method that contributes to real-time quantitative monitoring for materials in high temperature fields has been created and its usefulness has successfully demonstrated.

Academic Significance and Societal Importance of the Research Achievements

本研究で得られた成果は、これまで困難とされていた高温場での超音波モニタリング、特に界面や材料内部の温度情報の定量評価を可能にすることにその学術的意義がある。また、その手法を活用することで、これまで未開拓であった各種材料加工プロセスの見える化を実現するもので、幅広い分野における材料加工のDX化を加速させるという点で社会的意義が大きいと考える。
