Abstract : Recent techniques in defects and materials characterization are reviewed and some of them selected to be implemented at INTA's Ultrasonic Lab. Previous work includes design and manufacture of several items (ultrasonic test bed, facsimile recorder) as well as familiarization with instrumentation. Main effort in this first year has been devoted to prepare software and to test it via elementary experiments on materials characterization. (Author)
