Locally Reversing Sensitization in 5xxx Aluminum Plate

Influence of Mg Content on the Sensitization and Corrosion of Al-xMg(-Mn) Alloys

“…The temperature dependence of DoS has been shown (for individual alloy compositions) in prior works, 22,25,30 which have revealed a lower DoS value for higher temperatures, consistent with Figure 9, when adjusting for time. 31 conclusIons v In this work we present the simultaneous influence of Mg content on the hardness, corrosion, and DoS of Al-xMg-0.5Mn alloys, where x varies from 3.36 wt% to 8.85 wt%. The hardness of the as-quenched alloys increased with an increase in Mg content.…”

Study of β precipitation and layer structure formation in Al 5083: The role of dispersoids and grain boundaries

“…The β phase corrodes preferentially compared with the Al-Mg matrix in most corrosive environments, which leads to intergranular corrosion and stress corrosion cracking [9][10][11]. In this case, the sensitization is defined as a microstructure where β phase precipitates on grain boundaries [12]. It is generally thought that β phase precipitates in binary Al-Mg alloys are formed following the reaction [13][14][15][16][17][18][19]:…”

“…Zhu et al [33] also reports precipitation of β phase along the grain boundaries as well as around and between preexisting particles. It has been shown that different types of dispersoids in 5xxx series Al alloys have a strong influence on the deformation behavior, recrystallization behavior and mechanical properties [12,34,35]. Although, it is known that β phase can form on preexisting dispersoids [5,7,33] [36].…”

Mechanical properties, intergranular corrosion behavior and microstructure of Zn modified Al–Mg alloys

“…Al-Mg alloys are widely used in transport and vehicle industries due to their good combined properties such as excellent corrosion resistance, weldability, formability, and high strength to weight ratio [1]. As now, mechanical properties and corrosion resistance of Al-Mg alloys are required to be further improved to broaden the application of these alloys in other fields.…”
