Toward high performance parmanent magnets for automotive applications
K. Hono
Nd-Fe-B based sintered magnets are the highest performance permanent magnets of today. Due to new applications for hybrid cars and electric vehicles, the demand for higher performance magnets that can be used at elevated temperature has increased. In this talk, I will discuss two approaches for developing higher performance permanent magnets for automotive applications, one is ultrafine grained Nd-Fe-B sintered magnets and the other is anisotropic nanocomposite magnets. Based on the new understanding on the structure-property relationships of sinterd and HDDR magnets obtained in our group, I will discuss the methodology to develop higher performance permanent magnets with the above two approaches.
