ORNL researchers win award for poster

Four researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) recently received the Best Poster Paper Award for their work presented during the fourth International Conference on Trends in Welding Research held in Gatlinburg, Tenn.

The award-winning presentation was based on a paper entitled Solidification Microstructures in Single-Crystal Stainless Steel Melt Pools. The authors are Lynn Boatner of ORNL's Solid State Division and Stan A. David of the ORNL Metals and Ceramics Division. Boatner and David are corporate research fellows of Lockheed Martin Energy Research Corp. (LMER).

Contributing to the paper were Jeffrey P. Sipf, a former graduate student in materials science and engineering at the University of Tennessee, and Douglas Corrigan, a doctoral candidate at Rensselaer Polytechnic Institute in Troy, N.Y. Sipf contributed to the paper while conducting research at ORNL to fulfill requirements for his master's degree program. Corrigan contributed to the paper while working at ORNL as a participant in the Graduate Student Research Participation Program managed by the Oak Ridge Institute for Science and Education (ORISE).

Research support for work on the award-winning paper was provided by the NASA Microgravity Science and Applications Division and by the Division of Materials Sciences in DOE's Office of Basic Energy Sciences.

ORNL, one of DOE's multiprogram national research and development facilities, is managed by Lockheed Martin Energy Research Corp.
