DESCRIPTION:Lightweighting of the autobody structure is challenging on se
 veral fronts.  Advanced high strength steels are less formable than lowe
 r carbon alloys that have been used in \nthe past and multi-material str
 ategies that introduce light metals into the structure require the joini
 ng of dissimilar alloys.  During the past three years two research proje
 cts \nat Brigham Young University have focused on both forming and joini
 ng problems.  The forming project\, in collaboration with General Motors
  and supported by the National \nScience Foundation\, investigated the e
 ffect of retained austenite (RA) transformation on material ductility fo
 r Q&P 1180 and TRIP 1180 steels.  Different strain paths were \nimposed 
 on sheet specimens\, including biaxial tension\, plane-strain tension\, 
 and uniaxial tension\, while electron backscatter diffraction (EBSD) was
  used to identify phases \nat various levels of strain until failure.  R
 A transformation rates were found to be a function of both the strain pa
 th and the microstructure.  The joining project\, in \ncollaboration wit
 h Honda / Oak Ridge National Lab and supported by the Department of Ener
 gy\, focused on a solid state spot joining method for a dissimilar combi
 nation \nof AA7085-T6 and DP 1180.  Joints were tested in lap shear tens
 ion\, cross tension\, and t-peel configurations\, in order to evaluate s
 trength levels compared to required \nindustry standards.  Corrosion tes
 ting was also performed in order to evaluate whether various coating/adh
 esive combinations would allow for adequate protection of the spot joint
 s.
