Formation of Al15Mn3Si2 Phase During Solidification of a Novel Al-12%Si-4%Cu-1.2%Mn Heat-Resistant Alloy and Its Thermal Stability

Understanding the effect of Ni content on microstructure and mechanical properties of A384 HPDC alloy

“…There are numerous studies in the literature reporting results of Ni addition to Al alloys containing Si and Cu. The addition of Ni to Al alloys causes the formation of intermetallic compounds even at low concentrations because of the very limited solubility of Ni in solid Al [13][14][15][16][17]. Most of the existing studies about Ni addition to similar alloys reported that Ni collaborates with Cu and Fe to form new intermetallic phases or react with the existing intermetallics to change their chemical composition [9].…”

Enhanced mechanical properties of Al–Si–Cu–Mn–Fe alloys at elevated temperatures through grain refinement and dispersoid strengthening

“…Liao et al developed an Al-Si-Cu heat-resistant alloy by adding Mn and found that the tensile strength of the alloy at elevated temperature was improved, due to the formation of Mn-rich intermetallics [27]. Suo et al reported that there was no change in the morphology and size of the Mn-rich phase even after a harsh thermal treatment at 525°C for 20 h, indicating that Mn-rich phase had excellent thermostability [28]. Therefore, the addition of alloying elements such as Cu, Fe, and Mn is an efficient method for developing recycled aluminium alloys used in industries that demand heat-resistant components.…”

Microstructure, Properties and Corrosion Resistance of As-Cast Al-12Si-1.0Mn-0.6Mg-xSc Alloys

“…5a, the irregular white phase contains elements of Al, Si, Fe and Mn, which should be Al(Fe, Mn)Si phase. According to Ref [25],. the needle-like phase in the Al-12Si-1.0Mn-0.6Mg alloy is β-Al 5 (Fe, Mn)Si.…”
