Description
Positron Annihilation Spectroscopic techniques are required as sensitive and reliable methods to study defects in metals and alloys. One of the well-known techniques namely Doppler broadening line-shape measurement has been set up at PINSTECH using high resolution HPGs spectrometry. Some preliminary results have been obtained and heat treated Inconel-825 which is nickel base super alloy. Clear difference can be seen in the broadening of 511 keV annihilation line as well as line-shape S-parameter with respect to aging time. (authors)
