In this laboratory, we are conducting research to improve the reliability and stability of the system by improving the functionality of each machine component. Aiming to improve the potential of the system and to realize an energy-saving and highly efficient mechanical system, we are engaged in research for the design of high-performance machines. The main research topics are as follows; ① Development of dynamic crystallization process of powder metal by “compressive force and shear force”, ②Development of consolidation process for high-performance materials by medium-temperature severe plastic deformation technique, ③Development of electromagnetic functional materials for “sensing and actuators”, ④ Clarification of hydrogen embrittlement mechanism by electromagnetic sensing.

Development of dynamic crystallization technology of powder by “compressive force and shear force”

To Develop high-strength materials with fine crystal grains using the “compression shearing method” that solidifies metal powder and wire materials at room temperature by severe plastic deformation.

Development of consolidation process for high-performance materials by medium-temperature severe plastic deformation technique

To Develop a method to directly solidify alloys and compounds from raw materials by the warm “compression shearing method” in the temperature region from room temperature to several hundred degrees.

Development of electromagnetic functional materials for “sensing and actuators”

To Develop materials and composite with excellent strength and electromagnetic functionality using physical and chemical methods

Clarification of hydrogen embrittlement mechanism by electromagnetic sensing

Hydrogen embrittlement mechanism of austenitic stainless steels has been investigated by a phase analysis using an eddy current testing (ECT) on hydrogen-charged fatigue test specimens.
