In the present work we report an anelastic spectroscopy study of pure FeCO3 (siderite) and of carbon steel samples covered by siderite films. Uncovered steel samples have also been investigated for reference. The siderite shows two relaxation processes below room temperature, at about 220 K and 140 K, while the covered steel sample displays only the peak at lower temperature. The presence of such a relaxation can be used to monitor the deposition of siderite. (C) 2009 Elsevier B.V. All rights reserved.

Abstract
In the present work we report an anelastic spectroscopy study of pure FeCO3 (siderite) and of carbon steel samples covered by siderite films. Uncovered steel samples have also been investigated for reference. The siderite shows two relaxation processes below room temperature, at about 220 K and 140 K, while the covered steel sample displays only the peak at lower temperature. The presence of such a relaxation can be used to monitor the deposition of siderite. (C) 2009 Elsevier B.V.
