Biography

   Dr Quadir received his PhD (2003) in Materials Science and Engineering from Hong Kong University (HKU), and then he continued a three years postdoctoral fellowship for conducting research in the field of sheet metal processing for car body and electric transformer. In 2006 he obtained a research fellowship in Australian Research Council Centre of Excellence for Design in Light Metals in the department of Materials Science and Engineering at The University of New South Wales (UNSW) Australia. Then he expanded his career as a Materials Research Manager in Electron Microscope Unit in UNSW for providing research and technical leadership to broader physical science research communities. His research interest includes thermo-mechanical processing of aluminum, magnesium, titanium, nickel and steel, two- and three-dimensional microscopy techniques, deformation and recrystallization studies and structure-property relationships in alloys and composites. Quadir’s research published in premium metallurgical and materials science journals.

Abstract

    Accumulative roll bonding (ARB) is a severe plastic deformation (SPD) process that has emerged with two exciting capabilities: (a) strengthens an ordinary piece of malleable metal by forming nano-structures and (b) produces novel layered composite structures by combining two or more metals. The process can be carried out in the existing rolling lines in sheet metal processing industries. In this presentation processing of some novel layered structures will be demonstrated for making the sheet light, strong and drawable. This presentation will include experimental characterizations with SEM, EBSD, TEM and FIB for developing fundamental understanding of the mechanisms that govern microstructural evolution during plastic deformation, phase transformations and recrystallization. The power of emerging three dimensional characterization techniques will be demonstrated in reconciling longstanding debates in materials science.
