中文摘要：
回转水纺丝法用快冷技术将熔融金属直接制备成细丝,可用于制备具有很高连续性和圆整度的丝材,并且能够改善合金的微观组织,提高材料性能。对该方法中喷嘴孔径、喷射速度和喷射距离等工艺影响因素,以及其对丝材性能的影响机制进行了综述分析。结合常见贵金属丝材的特点,由于回转水纺丝法可减轻常规凝固过程中的偏析,在多元合金丝材的制备中有潜在应用前景。据此用自制设备进行了初步实验,并提出了技术改进设想。
英文摘要：
In-Rotating-Water-Spinning （IRWS） method is a rapid solidification process, which can produce thin wires straight from molten state, offering many advantages over the conventional wire drawing process. Wires of high continuity and roundness can be obtained by using this method. Moreover, It can improve microstructure and advance performance of the resulting wires. The factors influencing the properties of wires during the solidification are reviewed. These factors mainly include the orifice diameter, the ejection velocity and distance. As RWS can reduce the segregation during the solidification and considering some characteristics of precious metals, we will find its potential application in the manufacture of multi-element alloy wires. Preliminary experiments have been carried out on the self-made device and future improvement on the process was proposed.
