场诱发相变驱动材料研究

The Research on the Field Induced Phase Transfonnation in Actuator Materials

从驱动组元的工作机理角度,系统分析了目前可用于智能材料系统中的驱动材料,提出了场诱发相变驱动材料的设计思想,对场诱发相变的铁电体和反铁电体材料进行优化设计和制造,结果表明:研制场诱发相变的理想驱动材料是可能的。

In this paper, the definition of the ideal actuator materials has been given. The new type of actuator materials by combining field driving with phase transformation has been developped. The materials systems (just as BaTiO3) showing electric field induced phase transformatio'n have been researched. The results showed that the ideal actuator materials could be obtained by means of field induced phase tramsfrmation.
