The Influence of Cooling Rate on Microstructure and Mechanical Properties of AlSi9Cu3

The aim of this study was to determine the correlation between size and distribution microstructural constituents their cooling rate, as well mechanical properties rate AlSi9Cu3 aluminum alloy when cast in high-pressure die casting (HPDC) conditions. In other words, ultimate goal research for a at different rates. Castings with wall thicknesses were chosen, rates assumed each one. from industrial technological practice systematically probes extracted those castings characterization properties. Special non-standard cylinders created on which compressive tests carried out. uniqueness lies fact that diameters designed direct actual thickness castings. This is important because solidification metal cavity complex, are higher surface than center. Local in-casting determined using numerical simulations. It discovered increasing 60 K/s 125 values strength 5% deformation increased average 261 MPa 335 MPa.
