Abstract

It presents a new technology and device for rapid quenching of melt in order to produce ribbons with metastable structures. The method advantages are presented. It is estimated, based on obtained structures that the amount of cooling rate achieved with this installation is 105-106 °C/s. Obtained metastable structures of hypo-eutectic, eutectic, and hyper-eutectic Al-Si and Al-Cu alloys are analyzed.
