Opis:: The paper contains results of studies on the formation of oxide layers on 13CrMo4-5 steel long-term operated at an elevated temperature. The material studied comprised specimens of 13CrMo4-5 steel operated at the temperature of 455oC during 130,000 hours (steel 1) and 540oC during 120,000 hours (steel 2). The oxide layer was studied on a surface and a cross-section at the outer surface of the tube wall. The paper contains results of studies of porosity in the oxide layer. The oxide layer formed on the studied steel 1 is ~146 μm thick, while on the steel 2 ~248 μm. It has been found that steel 2 has higher porosity.

Opis:: The paper presents results of studies of steel and the oxide layer formed during a long-term operation (t=130,000h) on 13CrMo4-5 steel at an elevated temperature (T=455°C). The oxide layer was studied on a surface and a cross-section at the inner site of the pipe (in the flowing medium – steam side). The paper contains results of studies such as: light microscopy, scanning electron microscopy, X-ray phase analysis.

Tytuł:: Analysis of crystallite size changes in a hematite and magnetite formed on steel used in the power idustry
Autorzy:: Gwoździk, M.
Powiązania:: https://bibliotekanauki.pl/articles/297993.pdf
Data publikacji:: 2018
Wydawca:: Uniwersytet Warmińsko-Mazurski w Olsztynie
Tematy:: 10CrMo9-10 steel
hematite
magnetite
X-ray diffraction
crystallite sizes
Opis:: The paper presents results of studies on the crystallite sizes of oxide layer formed during a long-term operation on 10CrMo9-10 steel at an elevated temperature (T = 545° C, t = 200,000 h). This value was determined by a method based on analysis of the diffraction line profile, according to a Scherrer formula. The oxide layer was studied on a surface and a cross-section at the outer and inner site on the pipe outlet, at the fire and counter-fire wall of the tube. X-ray studies were carried out on the surface of a tube, then the layer’s surface was polished and the diffraction measurements repeated to reveal differences in the originated oxides layer.

Tytuł:: Changes of crystallite sizes in the oxide layer forming during long-term operation of 10CrMo9-10 steel
Autorzy:: Gwoździk, M.
Powiązania:: https://bibliotekanauki.pl/articles/298126.pdf
Data publikacji:: 2017
Wydawca:: Uniwersytet Warmińsko-Mazurski w Olsztynie
Tematy:: 10CrMo9-10 steel
oxide layer
X-ray diffraction
crystallite sizes
Opis:: The paper contains results of the studies on X-ray diffraction analysis XRD (studying the phase composition, crystallite sizes) of oxide layers on 10CrMo9-10 steel, operated for a long time at an elevated temperature (T = 525°C, t = 200,000 h). The oxide layer was studied on a surface and a cross-section at the outer on the inlet both on the fire and counter-fire side of the tube wall surface. X-ray studies were carried out on the outer surface of a tube, and then the layer surface was polished down and the diffraction measurements were performed again to determine crystallite size in oxide layers. Based on the width and the position of the main coat and substrate reflections, the size of the crystallites was determined using the Scherrer formula.
