“…Precipitation-hardened martensitic stainless steels, such as 17-4 PH, 13-8 PH, and 15-5 PH, which combine good mechanical properties with corrosion resistance, are widely used in industry applications [1][2][3][4][5][6]. For this kind of steel, the high chromium content ensures excellent corrosion resistance [7], and the outstanding strength derives from two main factors: martensitic hardening during the quenching process and precipitation hardening during aging treatment [8][9][10][11].…”

Heat treatment plays a decisive role in the microstructure of metallic materials. The effect of cooling rate changes caused by the quenching medium on the microstructure of steel materials should be clarified. In this study, the effect of the quenching cooling rate on the microstructure of two precipitation-hardened martensitic stainless steels was investigated. The mechanical properties and hydrogen embrittlement susceptibility effected by the changes in the microstructure were also analyzed. A slow tensile test and hydrogen pre-charging were carried out to obtain the hydrogen embrittlement susceptibility parameters of the specimens. The results show that the quenching cooling rate only affects specific microstructures, including the twin structure and misorientation angle. Before hydrogen charging, the mechanical properties of the precipitation-hardened martensitic stainless steels were not affected by changing the quenching cooling rate. After hydrogen charging, the hydrogen embrittlement susceptibility decreased as the quenching cooling rate increased.

“…Besides carburizing, other types of corrosion have an effect on the mechanical properties of steels such as hardness, elongation percent, yield stress, ultimate tensile stress, ductility, fracture stress, and wear resistance (15)(16)(17). Mechanical properties of hardening steels following carburizing or different thermal and coating treatments are investigated (18)(19)(20)(21). The effect of machining induced surface residual stress on the micro crack density of a steel was examined (22).…”

The aim of this study was to investigate the interaction of carbide nuclear fuels with steel that is being used as cladding material for nuclear reactors. The specimens prepared from steel EN 1.4988 were consecutively annealed in three uranium carbide (UC) powders, having different carbon contents, at 600 °C for 1000 h. Both Ar and Na were used as bonding elements. The increase in the carbon content of the carburized specimens was determined and evaluated according to the bound and free carbon contents in the UC powders. The migration of free and bound carbon atoms into steel via self-diffusion and over Fe3C formation is interpreted as carburizing. Microhardness measurements and stress-strain tests were used to determine the mechanical properties of crude and carburized steel specimens. Maximum hardness at the contact surface and depth of the carburized zone were determined from the microhardness profiles and discussed depending on the bonding elements and carbon content in the specimens. These variables have a significant impact on the elongation percent, 0.2% yield stress, and tensile stress.
