Collaborative Proposal: GOALI: AHSS: Sheet Formability and Springback of Advanced High Strength Steels

Colorado School Of Mines, Golden CO

Investigators

Abstract

An integrated, collaborative project among the Ohio State University (OSU), Colorado School of Mines (CSM) and General Motors R&D (GM) will remove the principal obstacles to the adoption of advanced high strength steels (AHSS) for automotive application: the inabilty to predict forming and springback and the identification of processing technologies to produce new materials with strength/ductility combinations superior to those available with current AHSS. Intellectual Merit: The project has three inter-related thrusts: 1. Process Development: Formability and springback measurement and simulation of existing AHSS and candidate alloys and microstructures devoloped in Thrust 2. 2. Material Development: Identification of new processing routes and microstructures upon which to base a 3rd generation of AHSS; validation of application readiness with methodologies developed in Thrust 1. 3. Educational Program: Education of promising and diverse students in AHSS-related technical areas at undergraduate and graduate levels; incorporation of Thrust 1 and Thrust 2 technical results into existing curricula. Broader Impact: Broader impacts in four principal areas are anticipated: 1. Benefits to Society: AHSS offer major improvement in automotive vehicle performance, cost, safety (personal security), energy savings, emissions, reliability, and durability. Nonetheless, adoption is uncertain without fundamental understanding. 2. Learning / Broadened Participation: The technical research program will be integrated into existing and new educational activities at the two institutions 3. Dissemination of Results: Project results will be widely disseminated in peer-reviewed journals and other avenues.
