BOISE, ID-In a project commissioned by Lockheed Martin Aeronautics, Positron Systems demonstrated that its Photon Induced Positron Annihilation (PIPA) and related technologies can measure the effectiveness of cold expansion techniques in metal alloys. The company says that this capability will lead to improved inspection intervals and lower maintenance costs in the aerospace sector. Further, with PIPA's multi-layer damage assessment capability, early damage in subsurface layers can be detected, thereby providing a method for quantifying damage without component disassembly.
