| Outline of Final Research Achievements |
In the study process of rapid solidification condition, we found a new method of controlling structure and properties. The structure, thermal stability and hardness can be systematically changed by the change of liquid ejection temperature, and the structure and properties can be controlled by controlling the ejection temperature. In addition, we developed soft magnetic iron-based glassy alloys with high saturation magnetic flux density of above 1.85 T by controlling the injecting temperature. Likewise, we found that clusters spontaneously formed in the amorphous phase and systematically changed in properties according to the difference in the bonding strength of the elements in the high entropy type glassy alloy. In the Al-based glassy alloy, a peritectic reaction reverse transformation was found to be Al + amorphous in the Al-Y-Ni-Co-Fe-Pd system from the Al + compound mixed phase in the high temperature region. Up to now, more than 20 papers on the mentioned results were published.
