The System of Labs Direct Fabrication Technology p:ogram was intended to foster cooperation and development in a cooperative effort between San&a National Labs, Idaho National Energy& Environment Lab and Oak Ridge National Lab. The goal of this program was to bring together LENS (Laser Engineered Net Shaping) from Sandi% INEEL's spray forming process and the alloy development expertise of ORNL. This program investigated the feasibility of combining the LENS and spray forming processes to exploit the best features of both approaches. Further, since both processes were thought to result m a rapidly solidified structure, the alloy design expertise of ORNL offered the opportunity for alloy design or processing options which could more fully utilize the unique capabilities of the processes.
