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.

各行业对提高生产率和材料性能的不断追求导致了新一代先进材料和新加工技术的发展，以进一步提高其内在能力。这些材料，特别是先进的结构钢和模具钢，是相对较新的，有迫切需要发展更好地了解合金化和加工（热处理和表面工程）对其微观结构和机械性能的影响，才能充分发挥其潜力。在这种背景下，本研究有两个主要目标：（1）应用HSLA钢技术开发（a）690-900 MPa级，坚韧和可成形的结构形状（棒和圆）和薄带）;（2）通过优化基体成分，热处理，包括深冷和选择性表面工程，提高模具寿命和性能。 将使用商业和实验先进钢。热处理和表面工程处理的特定组合将根据需要选择，以填补加工-结构-性能关系的基本知识空白。预计该项目的完成将扩大技术知识和科学基础，以提高加拿大制造商在民用基础设施、采矿、重型机械、汽车和航空航天领域的生产力。
