TL;DR: It was found that increase in acid concentration increased tubular membrane wall thickness that improved mechanical handling and that robust ceramic tubes with uniformly distributed pore-structure and parallel nano-channels of lengths and sizes practical for industrial applications were reliably produced in quantity.

TL;DR: In this paper, the authors proposed a paradigm change in designing products by including manufacturing-induced effects in the initial dimensioning, which will lead to lightweight components and serve environmentally benign designs.

TL;DR: In this article, the influence of the initial billet geometry on the product geometry during bi-material rod extrusion has been investigated and both physical and numerical modeling techniques have been used in this study.

TL;DR: In this article, a four-turn equal channel angular pressing tool was integrated into an extrusion die (iECAP die) to improve the mechanical properties of profiles extruded from aluminum chips.

Abstract: ALUMINUM AND ALUMINUM ALLOYS are very suitable for extrusion and many types of profiles can be produced from easily extrudable alloys (Fig. 1, Ref 1). Aluminum extrusion is a very competitive technology for creating profiles for new products with short lead times, a wide range of properties associated with various alloys, and design flexibility. The widespread use of aluminum extrusions is due to the versatility of applications from the combination of the extruded product form and the material characteristics of aluminum. Applications may be linked to the advantages of extruded profiles, or both. The basic material characteristics of aluminum and its alloys include (Ref 1–7):
