摘要
Precipitation in Inconel 625 alloy has been studied by positron annihilation spectroscopy and electron microscopy. The observeddependence of annihilation characteristics on aging time is attributed to the change of the positron state due to the increaseand decrease of the density and size of the γ″ precipitates. Hardness measurements and lifetime measurements are in goodagreement.
