In this study, mechanical behavior of HY 80 steel in various mediums such as solutions of HCl, H2 S0 4 and NaOH has been investigated experimentally. The plate specimens, tensile specimens and V-notched specimens are immersed in solutions of HCl, H2 S0 4 and NaOH. Mass losses of immersed HY 80 flat plate specimens are measured after 1 week, 2 weeks and 4 weeks for each H2 S04 , NaOH and HCl solutions to determine the aggressivity of the corrosive medium to surface of HY 80 steel. Also, tensile specimens and V-notched specimens are immersed for 1, 2 and 4 weeks to study on the effect of corrosive medium on fracture toughness and yielding behavior of HY 80 steels. The results show that however, yielding strength and ultimate tensile strength of HY 80 steel have reduced after immersed in acidic solutions of HCl and H2 S04 , are stable after immersed in solution of NaOH. Furthermore, effect of acidic medium lower the fracture toughness of HY 80 steel.

“…It consists primarily of aluminium, along with small amounts of magnesium, manganese, chromium and other trace elements. Its unique combination of mechanical properties and corrosion resistance makes it well-suited for the aerospace [2,3] naval [4] and construction [5] industries. Some relevant reports concerning the formability and corrosion behaviour of this alloy are presented below: Ezuber et al [6] studied the corrosion behaviour of 5083 and 1100 aluminium alloys in seawater at 23 and 60 • C. These researchers found that the breakdown potential of the two alloys decreased with an increase in test temperature, whereas 1100 aluminium alloy had slightly better corrosion resistance than 5083 aluminium alloy.…”

Aluminium–magnesium alloys find widespread application in diverse industrial and technological fields owing to their unique characteristics such as lightweight nature, favourable physical and mechanical properties, corrosion resistance and cost-effectiveness. During production, these alloys often undergo various forming processes that significantly affect the morphology and microstructure of their surface layers. Consequently, the surface properties, including corrosion resistance, are notably influenced by these treatments. In this study, the impact of cold rolling on the corrosion behaviour of the 5083 aluminium alloy, which is considered as an important alloy for the aerospace and naval industry, was investigated. The 5083 Al alloy underwent a cold-rolling process, resulting in specimens with reduced average thicknesses of 7% and 15%, respectively. The microstructure of the alloy was examined by using X-ray diffraction, optical and scanning electron microscopy techniques. Furthermore, the corrosion behaviour of both the as-received and cold-rolled aluminium alloy specimens was evaluated through potentiostatic and potentiodynamic corrosion measurements. The experimental results demonstrated that higher cold deformation percentages, within the specified experimental parameters, led to an enhanced corrosion resistance for the alloy. This improvement was primarily attributed to the reduction in grain size induced by recrystallization and to the formation of a passivating aluminium oxide film.

“…One of the major metal alloys that are commonly used in different industrial applications is Al alloys, due to their properties, for instance, formability, strength-to-weight ratio, corrosion resistance, and weldability [1][2][3][4]. Different types of Al alloys are widely used in numerous industrial applications, such as aerospace, automotive, construction, marine fabrication industries, electrical engineering, and biomedical applications [5][6][7][8][9][10][11]. Most Al alloys have superior mechanical and electrical properties compared with Al (1050) alloy properties.…”

Aluminum alloys use is so profound in many applications such as transportation, construction, energy, defense applications, automotive, aerospace, to name a few. Therefore, investigating the mechanical and electrical properties of the different types for aluminum alloys is vital. The Al–Mg alloy is widely used in the automotive industry because of its optimal properties, for example, corrosion resistance, weldability, and strength-to-weight ratio. This study aims to investigate and model the effect of changing the magnesium percentage content on the hardness and electrical conductivity of Al–Mg alloy with a detailed statistical analysis to validate the results. The microstructure at each Mg percentile content is demonstrated using a scanning electron microscope (SEM) and an optical microscope for validating the Mg content after solidification and tracking the grain size evolutions at different Mg percentiles. Vickers hardness testing is applied for hardness evaluation at each experimental condition. The electrical conductivity is tested using a PCE 20COM electric conductive non-destructive test (NDT). Prediction models are constructed to estimate the hardness and electrical conductivity as a function of Mg percentile by using a nonlinear optimizer. The results indicated that the hardness is significantly increased with increasing the Mg content by three times when comparing 0 Mg wt.% and 5 mg wt.%. In contrast, a 48% reduction in the electrical conductivity is found when Mg wt.% is increased to 5 and a notable decrease in the grain size is observed when the Mg content is increased.
