Workshop On Addressing Key Technology Gaps in Implementing Advanced High-Strength Steels For Automotive Lightweighting

                        ORNL  PNNL

February 9-10, 2012, USCAR Offices, Southfield, MI

Objective:  This workshop was devoted to developing research and applied technology topics aimed at overcoming the key technology gaps which are hindering the lightweighting potential of increased use of AHSS in automotive applications. 

Background:  Although great progress has been made in implementing 1st generation and developing 2nd and 3rd generation AHSS for vehicles, recent industry studies have indicated that we haven't reached the limits of lightweighting possible by using AHSS, and that there are still technology gaps that, if overcome, would increase the usage of AHSS, and accelerate its implementation.  The U.S. DOE has publicly recognized this fact in several recent presentations, and this workshop would be aimed at identifying the research topics and approaches that could be used to close the gaps.  Ultimately, the results of this workshop would be used by investigators to develop proposals to execute the identified research.
