中文摘要:
这个工作在一条建议快速的形成的途径下面调查结构的进化和金属性的眼镜(MG ) 的机械性能。通过唯一的超声帮助微注射方法,有好维的精确性的微 MG 部分成功地被制作。温度在微注射期间比玻璃转变温度高、比结晶化温度低。MG 微部分在超声帮助以后把非结晶的性质作为的微分扫描热量计曲线和 X 光检查衍射模式表演微注射。我们的结果为 MG 的快形成建议一条新奇线路并且在微规模产品和设备的快速的制造有有希望的应用。
英文摘要:
This work investigates the evolution of structure and mechanical performance of metallic glasses(MGs)under a proposed rapid forming approach. Through the unique ultrasonic-assisted micro injection method, micro MGs parts with fine dimensional accuracy were successfully fabricated. The temperature during the micro injection is higher than the glass transition temperature and lower than the crystallization temperature. Differential scanning calorimeter curve and X-ray diffraction pattern show that the MGs micro parts keep the amorphous nature after the ultrasonic-assisted micro injection. Our results propose a novel route for the fast forming of MGs and have promising applications in the rapid fabrication of micro scale products and devices.
