The transformation behavior of metallic glass was measured during rapid heating with the experimental apparatus developed in this study. The thin film specimen wasrapidly heated by resistance heating and measurement methods were developed on the temperature, electric resistance, stress relaxation, glass transition behavior. The fundamental study was also carried on the viscous behavior of Zr-based glassy alloy under rapid heating. During the rapid heating, glass transition temperature Tg and crystallization temperature Tx increase with increasing heating rate. Furthermore, the normal viscosity decreases with increasing heating rate. This phenomenon contributes to high throughput nanoimprinting. High throughput nanoimprinting system was developed in this study. The system for metallic glasses is effective for mass production.

利用自行研制的实验装置，测量了金属玻璃在快速加热过程中的相变行为。通过电阻加热对薄膜样品进行快速加热，建立了薄膜样品的温度、电阻、应力松弛、玻璃化转变行为的测量方法。对快速加热条件下锆基玻璃合金的粘性行为进行了基础性研究。在快速升温过程中，玻璃化转变温度Tg和晶化温度Tx随升温速度的增加而增大。此外，法向粘度随升温速率的增加而降低。这一现象促成了高通量的纳米压印。本研究开发了高通量的纳米印迹系统。用于金属玻璃的系统对于大规模生产是有效的。
