“…The hardness values exhibit peak at 9 h, resulting from the presence of several hardening phases, including Al 2 Cu, Mg 2 Si and Al 7 CuNi which contribute to the precipitation hardening of the alloys. Similar observations were recorded and explained for Al-Si-Cu-Mg 380 alloy by Muzaffer Zeren [8]. The ultimate tensile strength shows the maximum after aging at 180°C for 9 h. The ultimate tensile strength increase with an increase in aging time and reaches a maximum at 9 h and decreases after aging for 9 h. After 9 h the specimen is over aged with an increase in aging time.…”

Al-12Si-3Cu-1 Mg-1.78Ni alloy is widely used for piston parts in automobile industry. The present paper investigates the effect of aging time for 1-16 h at 180°C after solution treatment of the alloy at 500°C for 5 h, on alloys prepared by gravity casting and squeeze casting. The wear rate of the alloy shows a minimum at an intermediate aging time. The hardness and ultimate tensile strength showed a peak at intermediate aging time. Mechanical properties and wear resistance are found to be better in squeeze cast alloy. The result are explained based on the microstructure developed during casting process and on heat treatment for various durations.

“…The addition of Cu increases considerably the strength of Al-Si alloys, due to precipitation of dispersed Al 2 Cu (θ) phase during aging. The strengthening contribution from precipitation is typically a function of both precipitate size and fraction (Haque and Maleque 1998;Wang et al 2003;Guo and Shah 2005;Zeren 2005;Kim and Buchheit 2007;Rosliza et al 2008).…”

In this study, the influence of Cu content on the hardness and microstructural characteristics of sand cast Al-Si-Cu alloys have been investigated. Al-Si alloys with 2% and 5% Cu have been utilized for this purpose. Solidification of Al-Si-Cu alloys have been realized by melting in a gas furnace with a crucible and casting in green sand molds at 690°C. The solution treatment has been performed at 500°C for 7 h and then specimens were quenched in water. The samples have been aged at 190°C for 15 h to observe the effect of aging on mechanical properties.

“…As the result of nonequilibrium solidification the as-cast -Al dendrites are cored with respect to copper. The copper content increases continuously from a minimum at the dendrite spine to the solubility limit at the edge of the dendrite in contact with the interdendritic micro-constituents [8][9][10] . The average copper content of the -Al dendrites is substantially below both the nominal alloy composition and the solubility limit.…”

To develop a software to predict the evolution of microstructure and the development of mechanical properties during the heat treatment of cast aluminum alloys, we modeled the redistribution of solute during the solution treatment of multicomponent alloys. The predictions of solidifi cation simulation software or the results of experiment provided the initial microstructure and solute distribution for simulation of heat treatment. Binary through quinary aluminum alloys with silicon, copper, magnesium, and iron were modeled. The basic model assumed local equilibrium (no undercooling due to nucleation or growth) and computed diffusion in the solid constituents during solidification. The evolution of microstructure during solution treatment was followed by qualitative and quantitative metallography. The results of simulation for the ternary alloy Al-7%Si-3.5%Cu were compared to experimental observation.
