Abstract Scope |
Engineeringly, small-sized wire-shaped products present the best combinations of mechanical properties but the path for manufacturing sub-millimeter wire often consists of many processes. The idea of the direct casting of wire, therefore, remains attractive because of the potential to eliminate intermediate processes that in principle can lead to cost and energy savings. Reported cases of wire casting are fraught with imprecise process parameters, inconsistent products, and a small scale. In this work, we report the parameters for a three-strand casting process that produced Fe-based amorphous structured wires. The castings were conducted in laser-drilled crucibles. The effects of melt superheat, nozzle design, orifice spacing, wire formation, and thermal properties were studied. It is shown that melt superheat of less than 100K and orifice spacing of more than 1mm are required to produce smooth and amorphous structured wires. The thermal stabilities were composition-dependent and mechanical properties ranged from 3000 – 4000MPa. |
