Abstract
The effect of hydrogen on the properties Al-Li alloys were investigated by using three tritium tracer techniques ; cold trapping, radio-gas analysis and tritium transmission electron microscopic autoradiography. The tracer tritium was doped to the specimen by cathodic charging in tritium water and the release characteristics during the temperature increase were analysed using cold trap and radio-gas analyser methods. The corresponding structural changes were examined by transmission electron microscopic tritium autoradiography (1).
