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.

俄亥俄州州立大学（OSU）、科罗拉多矿业学院（CSM）和通用汽车研发部（GM）之间的一个综合性合作项目将消除先进高强度钢（AHSS）在汽车应用中的主要障碍：无法预测成形和回弹，以及确定生产新材料的加工技术，这些新材料的强度/延展性组合上级现有的AHSS。工艺开发：在Thrust 2.2中开发的现有AHSS和候选合金以及显微组织的成形性和回弹测量与模拟。材料开发：确定新的加工路线和微观结构，以作为第三代AHSS的基础;使用Thrust 1.3中开发的方法验证应用准备就绪性。教育项目：在本科和研究生阶段，在AHSS相关技术领域培养有前途的多样化学生;将第一和第二重点技术成果纳入现有课程。更广泛的影响：预计将在四个主要领域产生更广泛的影响：1.对社会的益处：AHSS在汽车性能、成本、安全性（人身安全）、节能、排放、可靠性和耐用性方面提供了重大改进。 然而，如果没有基本的理解，采用是不确定的。学习/扩大参与：技术研究计划将融入两个机构的现有和新的教育活动3。成果的传播：项目成果将在同行评审期刊和其他渠道广泛传播。
