About

Dr. Moataz Attallah is a lecturer in advanced materials processing. He received his PhD in metallurgy and materials science from the University of Birmingham (2007), BSc (highest honours) and MSc degrees from the American University in Cairo (AUC) Egypt, in mechanical engineering, and materials/manufacturing engineering respectively. Following his PhD, Moataz worked as a research fellow at the University of Manchester Materials Science Centre from January 2007, prior to his appointment as a lecturer at the School of Metallurgy and Materials at the University of Birmingham in June 2010.  

His research portfolio over the past 10 years has been focused on studying the phase transformations, microstructure-property and residual stress development in friction-based welding technologies (friction stir, inertia, and linear friction welding) and laser fabrication technologies (blown powder and laser powder bed) in aluminium, titanium, and nickel-base superalloys, through research partnerships with Rolls-Royce plc, BAE Systems, TWI, and Novelis technology. This work combines a wide range of experimental techniques, including synchrotron x-rays and neutron diffraction, electron microscopy, in-situ high temperature confocal scanning microscopy, and mechanical properties characterisation. He co-authored 20 journal and conference papers (16 as the lead author), 1 book chapter, and several industrial reports.

Qualifications

PhD in Metallurgy & Materials Science, University of Birmingham, 2008
MSc in Materials & Manufacturing, The American University in Cairo, 2003
BSc Hons in Mechanical Engineering, The American University in Cairo (Egypt), 2001

Biography

Moataz Attallah received his BSc (highest honours) and MSc in mechanical and materials/manufacturing engineering, 2001 and 2003 respectively, from the American University in Cairo, Egypt. He went on to study for a PhD in Metallurgy and Materials Science from the University of Birmingham between 2003 and 2007. He then worked as a research fellow between January 2007 and June 2010 at the, University of Manchester’s School of Materials. In Manchester, Moataz was a member of the Stress & Damage Characterisation Unit (led by Professors Phil Withers and Michael Preuss), which is the largest research group in Europe with a research portfolio focused on neutron and synchrotron x-ray diffraction. During that period, Moataz had a brief spell at Osaka University in Japan, where he worked on in-situ confocal microscopy in Prof. Komizo’s laboratory.  

From June 2010, he returned to the University of Birmingham as a lecturer in advanced materials processing. His research portfolio over the past 10 years has been focused on studying the phase transformations, microstructure-property and residual stress development in friction-based welding technologies (friction stir, inertia, and linear friction welding) and laser fabrication technologies (blown powder and laser powder bed) in aluminium, titanium, and nickel-base superalloys, through research partnerships with Rolls-Royce plc, BAE Systems, TWI, and Novelis technology. This work combines a wide range of experimental techniques, including synchrotron x-rays and neutron diffraction, electron microscopy, in-situ high temperature confocal scanning microscopy, and mechanical properties characterisation. He co-authored 20 journal and conference papers (16 as the lead author), 1 book chapter, and several industrial reports.

Moataz is a member of the Welding Institute (MWeldI), and also a member of the Global Young Academy (http://www.globalyoungacademy.org/), which is an international organisation for young academics.

Moataz is also the academic theme leader for near net shape manufacturing theme for the Manufacturing Technology Centre (MTC), which is a collaborative initiative between the Universities of Birmingham, Loughborough, and Nottingham, TWI, and leading UK manufacturers such as Rolls-Royce plc., Airbus UK, Aero Engine Controls. MTC provides an environment in which world-class providers of research and development in key manufacturing technologies work alongside high-value manufacturing industries in transferring and exchanging knowledge focussed on delivering user-driven advanced manufacturing solutions
