J.A. Szpunar joined the Department of Mechanical Engineering at the University of Saskatchewan in August 2009, coming from McGill University where he was Professor of Materials Science and Birks Chair in Metallurgy. His research interests extend to various areas of materials related investigations. In  particular he has longstanding interests in deformation and recrystallization processes in metals; in structure and properties of thin films; in electronic interconnects; in high temperature oxidation and corrosion; in synergy of wear, erosion and corrosion; in the  applications of X-ray and neutron diffraction techniques to structure of grain boundaries and other interfaces; in hydrogen ingress into nuclear materials; in intergranular fractures; in fatigue and failure; and in superplasticity and other special properties of  nanocrystalline materials. 

More recently his research has focused on environmentally friendly energy generation, in particular the extraction and purification of hydrogen, and research on materials used in Candu reactors and Generation IV nuclear reactors. This CRC proposal would create a Canadian Center of innovative research in selected areas of materials development and testing, along with novel techniques to support clean energy programs. The proposed CRC program will also include research on more safe and secure methods and materials for oil and gas transportation.

Dr Szpunar has a remarkable record of research productivity. During his 22 years at McGill, 27 PhD students and 15 MEng students graduated under his supervision, and an additional 5 PhD projects are currently close to completion. He was a leader of 49 major research projects ? mostly materials related investigations. The results of his research are presented in 582 research papers (350 in refereed journals papers and 232 in refereed proceedings and as non-refereed publications). During his time at McGill he founded the ?Textures & Microstructure Laboratory?, now recognized as a leading world center of microstructural research. Dr. Szpunar?s record of research contributions demonstrates his ability and readiness to undertake those upcoming challenges successfully and with continued high productivity.


1. Novel experimental methods for investigation of texture:

At an early stage of his academic carrier Dr Szpunar proposed and developed a new neutron diffraction method for texture and stress investigation in metal sheets and other materials. He also proposed and implemented the application of neutron TOF method for texture investigation . These methods are now used in almost all nuclear research centers throughout the world. The methods were described in an extensive review (a) prepared for the International Atomic Energy Commission and distributed in all nuclear research centers associated with this agency.

The Nominee proposed also the  application of energy dispersive diffraction to  texture studies (b) and for the first time demonstrated this application.

2. Modeling and simulation of texture and microstructure:

Dr. Szpunar pioneered the application of Pot?s methods of microstructure description for simulation of microstructural and textural evolution during annealing and electro-deposition processes.  In particular he proposed new models of texture transformation during nucleation, recrystallization and  normal or abnormal grain growth in industrial manufacturing processes. These models supported by experiments offered innovative approached towards fundamental understanding of microstructure and  texture  transformation of  steels  and  aluminium alloys during annealing processes.  The results obtained were presented in 10 Acta Materialia papers.  Some of the  concepts  developed  in this research were used  to propose improvement of the process of manufacturing magnetic  steels by Kawasaki Steel (Japan) and  Posco  (Korea).

3. Magnetism and crystallographic texture:

Methods were developed that allowed explanation of texture influence on the magnetic properties of various hard and soft magnetic materials and perpendicular magnetic recording media. Also, a unique method was proposed to obtain from the neutron diffraction pole figure measurements the information about the distribution of magnetic moments in polycrystalline textured materials.  This was the first time that such a distribution was obtained.  This research was published in (e) Phys. Rev B. Development of the method for magnetic texture study might have important impact via better understanding of the magnetization processes in textured soft and hard magnetic materials. Various other innovative  methods were  developed by the applicant leading  to a  better understanding of correlation  between texture  and  magnetic properties., Some papers related to these problems are listed below :

4. Development of methods for improvement of high temperature oxidation resistance:

A new method based on a control of surface texture and application of reactive element coatings was applied to nickel and some nickel alloys. It was shown that the proposed method can improve the oxidation resistance by two orders of magnitude. The model of oxidation control was verified experimentally.  Research on this subject was described in 22 research papers, including:

5. Oxidation and hydrogen ingress in Zr-Nb alloys.

Pressure tubes in CANDU reactors are made of a zirconium alloy containing 2.5% niobium. One of the factors limiting the life of these components is hydrogen ingress and consequent hydride formation, leading to embrittlement and fracture. We have developed novel microstructural model of  oxidation and oxide  texture  development (e,h) microscopic model of  hydrogen ingress, identified novel  structural  transformation in zirconium oxide (a,b,l) and discover important correlations between texture of oxide and the rate of hydrogen ingress.  The correlation proposed may be a unique tool for assessment the tube quality prior to installation for service, and for evaluation of potential risk of failure.  Importance of  this research is  illustrated  at best by the  support obtained  from AECL for three Strategic NSERC grants of the  applicant. The results obtained can be extended to other  Zr alloys  that  are major  structural components of almost all nuclear reactors.  Examples of  papers published in this area are:
