Title: PNGV Superplastic Forming of Stainless Steel Auto Components (USCAR) Final Report CRADA No. TC-0881-94

Abstract

The DOE/DP CRADA consisted of three tasks that were to be performed concurrently by LMES and LLNL. LMES evaluated mechanical properties of candidate duplex stainless steel alloys at various temperatures and strain rate to determine forming behavior. LLNL evaluated the weldability and the effect of the heat affected zone (HAZ) from the weld on the microstructure of duplex stainless steel. At the beginning of the CRADA, commercially available duplex stainless steel was purchased to provide material that would have optimum characteristics. Superdux 65 (SD65) was acquired and tested and was used to form initial test parts. LMES cast and processed a couple of duplex stainless steel alloys that exhibited superplastic forming (SPF) behavior in case a domestic material was unavailable.
