“…The values of corrosion potential, the corrosion current, and the vortex potential for all measurements along with their standard deviations are presented in Table 4. Using the polarization curve, current density is determined by the Tafel extrapolation method [46][47][48]. Extrapolation is generally conducted using both cathodic and anodic branches of the polarization curve.…”

Quenching affects the mechanical and corrosion properties of precipitation-hardenable alloys such as aluminum alloy 7075-T6 (AA7075-T6). In this paper, the properties of as-quenched AA7075-T6 are predicted within the framework of quench factor analysis (QFA), using cooling curves obtained from a quench test. Theoretical and computational approaches are used to predict spatial and temporal variations of temperature. The temperature variations are used to predict the quench factor and consequently the material properties. A test is carried out on a block of AA7075-T6 quenched partly in water and partly in air followed by hardness measurements and electrochemical characterizations. The results show that the hardness and the corrosion potential of the quenched block decrease as the cooling rate decreases. The results further suggest the existence of a corrosion product layer for the water-quenched part of the sample. This was not observed for the air-cooled part. A new corrosion prediction model is developed by using the QFA method, cyclic polarization, and electrochemical impedance spectroscopy test results. The present model may be used to potentially reduce the number of corrosion tests in evaluating corrosion properties of quenched AA7075-T6. Model predictions for corrosion and hardness are in good agreement with experimental results.

“…A further study has been carried out to determine the effect of tempering on the electrochemical corrosion properties of the Martensitic grade AISI4130, indicating that the heat treatment process leads to a decreased electrochemical corrosion current (IC) against 3.5% NaCl water saline solution. It also showed that the increased surface microhardness of the heat-treated material demonstrates the heat treatment process' ability to improve the electrochemical corrosion and abrasive wear resistance of the material [21]. Previous studies discussed the advantage of the tempering process after quenching step on the mechanical properties of the heat-treated carbon steel.…”

The current paper investigates the effect of the heat treatment process on three grades of stainless steel alloys against the abrasive and the lubricant wear conditions, using 25 wt.% glucose solution for the industrial agriculture applications. The heat treatment process was carried out for one hour at 900 ± 10 °C, followed by quenching with monograde motor oil and tempering for more than two hours at 200 ± 10 °C. Several analyses were conducted to estimate the final mechanical, surface morphological and tribological properties for the studied materials, before and after the heat treatment process. The heat-treated martensitic stainless steel grade exhibited superior wear resistance and higher hydrophobicity compared to the other two heat-treated austenite stainless steel grades. Therefore, the mechanism of the heat treatment process, the chemical and physical nature of the parent material, and the viscosity of the selected lubricant all influence the final behaviour of the studied material against the applied operating conditions for the selected application.

“…The material used in the current work was a low alloy carbon steel, the AISI 4130, containing chromium and molybdenum as strengthening agents. It is one of the most widely used low alloy steels for various applications due to its improved corrosion and wear resistance, hardenability, and enhanced mechanical strength for high temperature applications [25][26][27][28][29]. When designing and selecting low-alloy steels used in various equipment and structures, elastic and damping properties play a key role.…”

Elastic properties of materials and their changes with temperature are important for their applications in engineering. A study on the influence of phase composition of AISI 4130 alloy on Young's modulus (Ed), shear modulus (Gd), and damping (Q-1) was carried out by Impulse Excitation Technique (IET). The material characterization was carried out using confocal microscopy, XRD, MET, HV, and dilatometry. A stable structure, composed of ferrite (BCC) and pearlite (α-Fe+Fe3C), was obtained by annealing. Metastable structure of martensite (BCT) was obtained by quenching. The Ed, Gd, and Q-1 were measured, varying the temperature from RT to 900 °C. The values of Ed and Gd, at RT, were determined as 201.5 and 79.2 GPa (annealed), and 190.13 and 76.5 GPa (quenched), respectively. In the annealed steel, the values Ed and Gd decrease linearly on heating up to 650 °C, with the thermal expansion. In the quenched steel, weak changes in the dilatometric curve, Ed, Gd, and Q-1, in the range of 350-450 °C, indicated decompositions of the martensitic phase. Sharp decrease in the moduli and high peak of Q-1, was observed for both samples around 650-900 °C, revealing low lattice elastic stability of the phases during transformations α(BCC)+Fe3C↔γ(FCC).
