Foreword

The Fifth International Symposium on Aerospace Materials and Manufacturing: Advances in
Materials, Processes and Repair Technologies is organized by the Materials Performance and Integrity
Section, Iron and Steel Section, and Materials Science and Engineering Section of the Metallurgical
Society of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM). This bi-annual event held
under the umbrella of the Conference of Metallurgists provides a unique opportunity for researchers and
materials engineers from academia, industry and government laboratories to discuss and share the latest
advances in materials research and process development for aerospace applications. The formulation of this
international symposium program would not be possible without the support of many colleagues in Canada
and abroad. Particularly, the symposium organizers would like to express their genuine appreciation to the
keynote speakers who have agreed to share their insights in this constantly evolving technology field.

The technical program of the symposium features five sessions: High Temperature Alloy
Development, Manufacturing Processes and Modeling, Protective Coatings, Application Challenges, and
Repair Technologies and Light Weight Materials. While 26 presentations were made in these five sessions,
only 18 papers are published in this proceedings volume due to the proprietary nature of the rest. These
papers and the presentations, coming from countries worldwide (North America, Europe and Asia), deal
with a wide range of technical issues, including solution treatment of high temperature alloys,
manufacturing processes and modeling, advanced laser and linear friction welding techniques, diffusion
barrier and high temperature coatings, oxidation behavior, advanced Ni-base superalloys for small gas
turbines, mechanical properties and environmental evaluation, weldability of high temperature alloys, new
high strength anti-friction alloy system, and powder metallurgy processing of light weight materials. The
sequence of the papers appearing in this proceedings volume is the same as they were presented at the
symposium. It is our hope that the readers will find many of the research findings presented in these papers
are informative and useful.

The editors of this proceedings volume are grateful for the full cooperation from the authors to
ensure the quality and consistency of the published papers. They are especially indebted to Ms. Ronona
Saunders of the Metallurgical Society of CIM for her unfailing support in both organizing the symposium
and editing the manuscripts. We do hope that this proceedings volume remains as a valuable record of the
research accomplishments in aerospace materials and manufacturing.

Editors’ Biographies

Linruo Zhao is a Senior Research Officer at the Institute for Aerospace Research of the National
Research Council Canada. He received his B. Sc. (1982) and M. Sc. (1985) degrees in Materials Science
and Engineering from Shanghai Jiao-Tong University, and his Ph.D. (1988) degree in Physical Metallurgy
from Beijing Institute of Aeronautical Materials. After spending two years as a postdoctoral fellow at the
University of Manitoba, Dr. Zhao joined NRC as a Visiting Fellow in 1991 and subsequently became an
Assistant Research Officer in 1993. During his 20+ year professional career, Dr. Zhao has contributed to a
wide range of research topics from superplastic deformation of titanium alloys to the microstructure-
property relationships of Ni-base superalloys and titanium aluminides, materials properties modeling, and
erosion resistant and high-temperature coatings for gas turbines. He has authored and co-authored two
patents and more than 100 refereed papers in scientific journals and conference proceedings. Since the
incipience of the Aerospace Symposium of the Conference of Metallurgists in 2002, Dr. Zhao has
participated in this bi-annual event as an author and session co-chair.

Priti Wanjara is the Group Leader for Metallic Products Manufacturing at National Research
Council Canada Institute for Aerospace Research (NRC Aerospace). She earned her B. Eng (1993) and
Ph.D. (1999) degrees from McGill University in Metallurgical and Materials Engineering. Prior to joining
NRC Aerospace she worked with IVACO Rolling Mills (1997-2002) as a Product Development
Metallurgist. Since joining NRC Aerospace in 2002, she closely manages several projects with industrial
clients and academic collaborators on forging, welding and additive layer for manufacturing and/or repair
of advanced materials. As Group Leader, she manages the multi-disciplinary activities of various research
and technical officers, whilst aiming to develop scientific collaborations and/or business partnerships with
industry, academia and other government organizations to promote novel joining and forming technologies
to various industrial sectors, including aerospace, automotive and nuclear. Dr. Wanjara is the co-author of
over 90 refereed papers and 50 NRC reports. As a member of the Canadian Institute of Mining, Metallurgy
and Petroleum since 1993, she has actively participated for many years in the Annual Conference of
Metallurgists as technical program co-chairman, session chair and symposium chair. In 2010, Dr. Wanjara
was nominated to the position of 3rd Vice President of the Metallurgical Society of CIM. She has received
national awards including the ASM Canada Council Brian Ives Lectureship in 2008 and the Brimacombe
Award from the Metallurgical Society of CIM in 2009.

P.C. Patnaik’s current responsibilities as Director of the Structures & Materials Performance
Laboratory (SMPL), one of the five Laboratories of NRC Aerospace, include the management of the
research and development and testing evaluation of aerospace structures, materials/coatings for aircraft
engines, spacecraft applications and aeroacoustics & structural dynamics, NDE and airworthiness
certification related to various collaborative projects with Canadian industries and other Canadian
Government Departments. Dr. Patnaik received his bachelor’s degree in Metallurgical Engineering from
India, and his Master’s and Ph.D. in Materials Science & Engineering from McMaster University in
Canada in 1984. After spending 2 years at NRC-NAE as NSERC Visiting Fellow, he continued with
industry serving Orenda//Magellan Aerospace Corporation for 16 years. He joined the Institute for
Aerospace Research (IAR), National Research Council Canada in 2002 as Chief of Materials. A fellow of
the American Society for Materials International (1998), a distinguished Canada Council Lecturer in 2001
and a winner of the MacDonald Young Award in 2003 and of the Morris Cohen Award from CIM, Canada,
he is very active in the professional field of Aerospace Materials, representing many organizations such as
ASM, TMS, NACE and ASME-IGTI. Currently he is the Canadian Panel member in Metals & Ceramics
Panel (TP-1) in the TTCP Defence collaboration program in between Canada, USA, U.K, Australia and
New Zealand. He is also a member of the NATO-RTO-AVT Mechanical Systems and Materials Technical
Committee and is currently the Chair. He has published in excess of 130 technical papers in journals &
conference proceedings and 70 technical reports, edited books and conference proceedings and organized
