is unusual. By controlling the polarization switching it is possible to alter magnetization states as well due to parameter coupling, which can be used to store information. Using a one-of-a-kind scanning probe in research funded by ORNL's Laboratory Directed Research and Development program, Balke was able to select among final polarization states that have the same electrostatic energy but differ dramatically in elastic or magnetic order. Remarkably, the control of polarization switching allowed the authors to create the closure ferroelectric domain pattern, the precursor for the long-theorized ferroelectric vortex state. Funding for this work, published in Nature Nanotechnology, was provided by the Department of Energy's Office of Basic Energy Sciences and the National Science Foundation. The work was performed at ORNL's Center for Nanophase Materials Science. [Contact: Ron Walli, (865) 576-0226; wallira@ornl.gov]

MANUFACTURING -- Holey truck frames . . .

Heavy trucks are a little less heavy but just as safe and rugged because of steel rail frames provided by Metalsa Roanoke, which enlisted the help of Cam Hubbard and the High Temperature Materials Laboratory User Program at Oak Ridge National Laboratory. By working with ORNL, the Virginia manufacturer has refined a hole-cutting method that could cut 100 pounds to 200 pounds per truck for frames alone. This is the result of some beneficial residual effects of current hole-cutting methods. Metalsa supplies side rails and chassis components to about half of the North American heavy truck market, including Peterbilt, Kenworth, Volvo/Mack and Freightliner. Hubbard used the lab's neutron scattering residual stress mapping facility to determine the state of residual stresses associated with four different methods to cut holes in the steel. Through this effort, Metalsa hopes to eventually save up to 30 million pounds of steel per year. Total annual fuel sa
