Advanced Science, EarlyView.Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds

This study demonstrated the effect of solid fraction and forging pressure on mechanical properties of the product of wrought aluminum alloys fabricated by the indirect rheoforging through electromagnetic stirring (EMS). In addition to EMS, the rheological material was examined for its response to various pouring temperatures as the rheo-material was ...

Materials Science Forum, 2017
The effect of the different electromagnetic stirring frequency after low temperature pouring on microstructures and mechanical properties of Al-7Si-0.42 Mg-0.1Cu alloys was studied. It was found that the primary α-Al becomes smaller and tended to be spherical morphology, and the particles were uniformly distributed after electromagnetic stirring.
