“…Further it can be confirmed that XRD peaks of A 11 MM 3 or Al 4 MM overlaps XRD peaks at 32.4 and 42° and 76° represent A 11 MM 3 or Al 4 MM. 25,26 The formation ability from elements to compound can be evaluated by the electronegativity differences between elements. The larger the electronegativity differences are, the easier the formation of a metallic compound is.…”

Magnesium alloys are increasingly accepted in automobile industry owing to their greater strength-to-weight ratio. These qualities lead to less vehicle weight and better fuel economy. Therefore, in the present work an effort has been made to develop a new Mg alloy system that exhibits greater ductility together with greater mechanical strength. Misch metal is added in Mg-based alloys to investigate the changes in mechanical properties. The microstructure of alloys Mg-4Al-3Zn-3Sn-3Pb (H1) and Mg-4Al-3Zn-3Sn-3Pb-0.5MM (H2) are dendritic in nature while for Mg-3Zn-3Sn-3Pb-2Si (H3) the ''Chinese script'' Mg 2 Si intermetallic structure was obtained. The ultimate tensile strength and elongation of Mg-4Al-3Zn-3Sn-3Pb-0.5MM (H2) alloy are about 40% and 100 % higher than that of H3 alloy. The ultimate tensile strength, yield strength, and percentage elongation of H2 alloy are 170 MPa, 44 MPa, and 3.4%, respectively.

“…Of all the materials used to make the vehicle's independent suspension components, magnesium alloys have the lowest density, 1.74 g/cm3, which makes them 35% lighter than aluminum alloys, and over four times lighter than steel [21]. Magnesium alloys are characterized by good ductility, better noise and vibration damping characteristics compared to aluminum alloys, and excellent casting capabilities [22]. The biggest disadvantage of magnesium alloys is their high cost [23].…”

The paper gives a description of the material selection process for a steering knuckle of a passenger vehicle's independent suspension system, by using two quantitative methods of material selection: Weighted Property Method and Limits on Property Method. After the definition of property requirements that potential materials must meet, digital-logic method has been applied in order to calculate the weighting factors of said properties. The material selection process included the application of Cambridge Engineering Selector for the analysis of diagrams and property values of potential materials. The obtained results indicate that the Weighted Property Method leads to the conclusion that the optimal steering knuckle material is low alloy steel 25CrMo4, while the Limits on Property Method shows that aluminum alloy AlZn5.5MgCu T6 is the optimal material.

“…It also has a low elastic modulus, limited fatigue and creep resistance at elevated temperatures, and limited ductility and workability at room temperatures, because of the hexagonal closely packed (HCP) crystal structure [4, 5]. However, these challenges with magnesium are of less importance when compared to its lightweight, excellent specific strength, hot formability, cast‐ability, good ductility, machinability, sound‐damping capabilities, recyclability, and good electromagnetic interference‐shielding [6–9]. Magnesium is the lightest of all lightweight metals used in structural applications, with a density of 1.74 g cm −3 , which is about seventy‐eight percent lighter than steel (density of 7.86 g cm −3 ); and forty‐seven percent lighter than aluminum (density of 2.7 g cm −3 ).…”

This paper presents the electrochemical performance and microstructural evolution of friction stir welded joint of dissimilar AA1050 and AZ91D in seawater, for potential applications in the transportation industry. The corrosion behavior of the dissimilar weld was compared to the corrosion behavior of the parent materials, and similar welds of each alloy. The experiments were successfully conducted with an H13 hot‐working tool steel in butt‐joint configuration. The results revealed the presence of intercalated microstructure in the dissimilar weld and homogenous microstructures in the similar welds. The corrosion resistance properties of the parent materials and similar welds were higher than that of the dissimilar weld sample. The dissimilar weld has a current density of 3.83×10−5 A/cm2 and corrosion rate of 9.99×10−4 mm/year; and is most susceptible to corrosion, due to the galvanic coupling between the dissimilar alloys and intermetallic compounds. The similar weld of AA1050 has a current density of 1.99×10−7 A/cm2 and corrosion rate of 1.44×10−3 mm/year, while the similar weld of AZ91D has a current density of 8.58×10−6 A/cm2 and corrosion rate of 1.13×10−1 mm/year.
