“…Carbon steels or stainless steels, as lead (Pb), have been commonly used as materials for thermal and radiation shielding [12][13][14][15]. Recently, in order to increase the shielding properties, it is intended to use boron together with the steels.…”

In this paper, the radiation shielding properties of borided Fe-Ni binary alloys (Ni-60 wt.% and Ni-80 wt.%) as a function of boronizing parameters (time and temperature) have been investigated by using the fuzzy logic model. For this purpose, the linear attenuation coefficients of borided samples were calculated and fuzzy logic approach was applied to these values. The results showed that fuzzy logic approach can be used to predict the radiation shielding properties of borided Fe-Ni alloys for untested conditions.

“…The obtained results using comparison of K p confirm the obtained results in the first comparison. To get an idea about the chemical composition of oxide layers formed, we have followed a method proposed by several researchers [20][21][22][23] and that takes into account the constant parabolic oxidation K p and the chemical composition of the material (especially its chromium content). The formed oxides are: magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3 ), chromia (Cr 2 O 3 ) and spinels Fe 2−x Cr x O 4 .…”

Effect of Boronizing on the Oxidation Resistance of 316L Stainless Steel

The effect of boronizing treatment on oxidation at high temperature on 316L stainless steel was studied at 850, 900, 950, and 1000• C in air, for holding times between 0.25 and 24 h. The oxidation resistance of unboronized and boronized specimens was studied isothermally by thermogravimetric analyzer. The oxidation rate constant represented as a parabolic rate constant Kp was evaluated. Optical microscopy, X-ray diffraction, and the scanning electron microscopy were used for surface characterizations. The experimental results show that boronized coating increases the resistance of stainless steel 316l about twice and prevents oxygen from penetrating into the stainless steel substrate at the temperatures between 850 and 1000• C.

“…Recently, two methods consisting of boriding followed by a diffusion annealing process (DAP) have been proposed to allow the phase transformation from the FeB coating to the Fe2B coating [9,10]. A number of works for different purposes were also performed on different types of steel [11][12][13].…”

In this work, we present a study of the effect of diffusion annealing at 700• C for 1 h on the nature and properties of boride layers obtained on XC38 steel through a molten salt consisting of borax (Na2B4O7) and boron carbide (B4C). We evaluated the changes brought by the diffusion annealing on the morphology of the boride layer, the thickness of this layer, the distribution of elements in the steel, and the hardness. Comparing the results obtained allowed concluding that the diffusion annealing will completely transform the two-phase layer formed of FeB and Fe2B borides in a single-phase layer consisting of single boride Fe2B. The transformation of the two-phase boride into a single-phase boride is done with an increase in thickness of about 30% compared to the initial thickness of the sample. The values of Si concentration obtained in the underlying zone after the diffusion annealing treatment are more important than those obtained in the same underlying zone of samples borided directly by immersion in molten salt consisting of borax and silicon carbide (SiC).
