AbstractAbstract
[en] Samples of AS 508 Cl.3 steel, one from ELETROMETAL (Brasil-AE) and the other from VITCOVICE (Checoslovakia AV) were studied by means of metallography, Tem, Scanning microscopy, hardness, internal friction, and X-ray diffraction. The materials show martensitic (AE) and bainitic (AV) structures, due mainly to different heat treatments. Rockwell (60fkg) and Vickers (1 fkg/mm2) hardness measurements allow a projection for maximum toughness of 600-630 MPa, which is in good agreement with suppliers data. Metallographic results show the presence of 0,1-0,5 μm precipitates: an additional system of precipitates pf 1-10 nm was detected by TEM. The data represent the initial characterization for further Radiation Damage evaluation. (author)
