Until now, several different chemical formulae are used to refer to the intermetallic θ- and η-layers formed at the surface of hot-dip aluminized steel. To clear up the subsequent confusion, both layers were identified and characterized using sever

The temperature variations of the ferrous Mossbauer parameters for a synthetic ilmenite (FeTiO 3 ) have been determined and interpreted over a very wide temperature range (5–900 K). The Debye model of the lattice vibrations was used in interpreting
