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.

本研究中开发的实验设备在快速加热期间测量了金属玻璃的转化行为。通过电阻加热和测量方法加热的薄膜标本是在温度，电阻，应力松弛，玻璃过渡行为上开发的。基本研究还进行了基于ZR的玻璃合金在快速加热下的粘性行为。在快速加热期间，玻璃过渡温度TG和结晶温度TX随加热速率的增加而增加。此外，正常粘度随加热速率的增加而降低。这种现象有助于高吞吐量纳米印刷。在这项研究中开发了高通量纳米印刷系统。金属眼镜的系统对于质量生产有效。
