High strength steel advancements lead to new, life-saving material

There have been great advancements in the development of the high-strength steel and the need for additional enhancements continue to grow. Various industries have a need for structural components that are lighter and stronger, improve energy efficiencies, reduce emissions and pollution, increase safety and cost less to produce, particularly in the automotive industry.

A group of researchers in Wayne State University’s College of Engineering (Detroit, Mich.) are working to create advanced materials with high-yield strength, fracture toughness and ductility. Their efforts have led to the development of a new material consisting of bainitic steels and austempered ductile iron that has all these characteristics, ultimately resisting fatigue that can cause fractures in materials often with catastrophic consequences.

The group, led by Susil Putatunda, Ph.D., professor of chemical engineering and materials science in WSU’s College of Engineering, has focused on developing novel materials using a unique processing technique. These materials are processed from existing raw materials used in the steel industry and can be heat treated using currently available industrial austempering processes. According to Putatunda, this third generation advanced high strength steel has a number of advantages over the currently available steels currently being used in industry today.
