20 ENHANCING THE POSSIBILITIES OF MOSSBAUERSPECTROMETRY TO STUDYTHE INHERENT PROPEROES 

Room temperature Mossbauer spectra of rust from carbon steel (a) and weathering steel (b) submitted to total immersion tests in 0.6 M NaCI concentration for 42 days. 

In relation to goethite, the room temperature magnetic hyperfine fields are always below 38.0 T, which is the reference value of well-crystallized large-particle goethite [21,22]. The low hyperfine field values may be related to the small grain sizes as well as the alteration of the Fe neighboring due to anion and/or cation substitutions.
