...Yong Huang; Mason Morehead Various methods for the production of bulk nanostructured (NS)/ultrafine-grained (UFG) materials have been developed, including equal channel angular extrusion (ECAE), a form of severe plastic deformation. Using an ECAE NS/UFG copper bar as an example, this study has...

...J. Butler; P. Tiernan; A. A. Gandhi; S. Beloshapkin; S. A. M. Tofail This paper describes a novel process designed specifically for extruding small scale billets, between 850 ° C and 950 ° C , in very short cycle times of 10 min. Induction heated nonconventional isothermal extrusion (IHNCIE...

... Delphi Automotive Systems, Singapore, and the National University of Singapore for providing assistance while preparing the manuscript. Powder metallurgy technique coupled with hybrid microwave sintering and hot extrusion can be successfully used to synthesize Al–SiC nanocomposites. A uniform...

..., it is shown that, with this device, stage IV may be reached and analyzed on polycrystals as well as on single crystals. The second part is devoted to equal channel angular extrusion, which is known to promote grain refinement after several passes. A direct comparison of the crystallographic textures measured...

...S. F. Hassan; M. Gupta Nano- Y 2 O 3 particulates containing ductile magnesium nanocomposites were synthesized using blend-press-sinter powder metallurgy technique followed by hot extrusion. Microstructural characterization of the nanocomposite samples showed fairly uniform reinforcement...
