Twin-roll strip casting of advanced metallic materials

Metallic materials have historic and served as critical enablers of human progress, wealth, and wellbeing over millennia.Recently, the global demand for the development of environment-friendly and energy-saving technology has been increasing,with the aim to support the sustainability of metallic materials. Twin-roll strip casting(TRC) is one of the most cutting-edge technologies and a near-net-shape manufacturing method in the steel industry, which conforms to the green fabrication trend of next-generation high-performance metallic materials. By utilizing the dominant characteristics of sub-rapid solidification, and integration of solidification, solid-state transformation, and deformation; TRC has become a meaningful way to deal with the most challenging issues in the processing of metallic materials, and made a significant contribution to materials manufacturing.Hence, we review the TRC process of various metallic materials, including plain carbon steels, stainless steels, Fe-Si electrical steels, high-strength steels, clad steels, aluminum alloys, magnesium alloys, metallic glasses, and so on. This paper offers an outlook of future opportunities for various advanced metallic materials development through the TRC process, and inspires more in-depth research.
