Processing-structure-property realtions in advanced materials

The ever increasing quest for improved productivity and material performance in various industries has led to the development of a new generation of advanced materials and new processing technologies to further enhance their intrinsic capabilities. These materials, particularly advanced structural and die steels, being relatively new, there is the compelling need to develop a better understanding of the effect of alloying and processing (heat treatment and surface engineering) on their microstructure and mechanical properties before their full potentialities can be exploited. In this context, the present study has two main objectives: (1) application of HSLA steel technology to the development of  (a) 690-900 MPa grade, tough, and formable structural shapes (bars and rounds)  and thin strips); (2) Improving die life and performance through optimization of matrix composition, heat treatment  including deep cryogenics and selective surface engineering.  Both commercial and experimental advanced steels will be used. Specific combination of heat treatment and surface engineering treatments will be selected based on the need to fill in the fundamental knowledge gap in processing-structure-property relations. It is anticipated that the completion of the project will broaden the technological know-how and the scientific basis for the improving the productivity of Canadian manufacturers in the area of civilian infrastructure, mining, heavy machinery, automotive and aerospace.
