“…[11] To improve the wettability of TRIP steels, some researchers tried to suppress the oxidation by adding some surface active elements, one of which is Sb. An addition of Sb has been found to significantly affect the recrystallization of steels [12] and to suppress internal oxidation, [13] as well as to improve the texture of nonoriented Si steels. This was due to the formation of a texture rich in (100) grains in Si steels caused by the presence of Sb.…”

The present research deals with an investigation of the effect of alloying element additions (Si, P, and Sb) and water vapor content P H 2 O =P H 2 ¼ 0:01 to 0:13 ð Þ on the oxidation and decarburization behavior of transformation-induced plasticity (TRIP) steels in a gas mixture of 95 vol pct argon and 5 vol pct hydrogen/steam, by thermogravimetry (TG). The oxidation proceeds primarily as an internal oxidation front in the TRIP steels, but a thin external scale on the order of a micrometer thickness exists and is comprised primarily of fayalite ((Mn,Fe) 2 SiO 4 ) and ((MnO) x (FeO) 1Àx . The oxidation products are distributed near the surface and along grain boundaries. A comparison between calculated and measured oxidation curves indicated that the oxidation and decarburization are independent. The results for TRIP steels, both with and without an Sb addition, indicate that increasing Si and P contents accelerate, whereas Sb addition suppresses, both decarburization and oxidation rates. Water vapor content has no obvious effect on decarburization but has a pronounced effect on oxidation, and decreasing water vapor content decreases the oxidation rates.

The effect of phosphorus (P) on magnetic properties and also on recrystallization texture of non-oriented electrical steel sheets has been investigated to develop core materials with low core loss and high permeability. Specimens containing different amounts of P were cold-rolled to various thicknesses, i.e. with various cold-rolling reductions, and annealed for recrystallization and grain growth. Magnetic induction of the steel with a large amount of P was higher than that of the steel with a small amount of P. Moreover, magnetic induction of the steel with a large amount of P slightly decreased with reduction of sheet thickness, i.e. with an increase in cold-rolling reduction, whereas magnetic induction of the steel with a small amount of P dramatically decreased. The most effective way to reduce core loss was to reduce thickness of electrical steel sheets. Therefore, P-bearing thin gauge non-oriented electrical steel sheets achieved low core loss and high permeability. The typical magnetic properties of P-bearing non-oriented electrical steel sheets with a thickness of 0.27 mm were 16.6 W/kg in W10/400 and 1.73 T in B50. These excellent magnetic properties were provided by the recrystallization texture control by P. {111}͗112͘ component in recrystallization texture, which deteriorates magnetic properties of electrical steel sheets, was suppressed during recrystallization. Furthermore, {j 1 , F, j 2 }ϭ{25°, 10-15°, 45°} component significantly developed at the expense of {111}͗112͘ component during grain growth. P segregation at initial grain boundaries would be responsible for this texture evolution. Accordingly, P would greatly contribute to the improvement of magnetic properties of nonoriented electrical steel sheets through the recrystallization texture control.

High-resolution Auger electron spectroscopy has been used to study selenium surface segregation on an Sedoped FeSi alloy. The surface segregation of Se and impurities such as C, P and S was measured in situ in the analysis chamber of an Auger spectrometer under ultrahigh vacuum conditions in the temperature range 200-850°C. At elevated temperatures (T ≥ 850°C), co-segregation of Se and S was observed to occur by means of x-ray photoelectron spectroscopy. It was also found that the surface segregation of selenium critically affected reconstruction of the (110) surface microstructure of the FeSi alloy, resulting in the formation of (100) planes at 850°C.
