Giulio Timelli, Daniele Caliari, Jovid Rakhmonov. Influence of Process Parameters and Sr Addition on the Microstructure and Casting Defects of LPDC A356 Alloy for Engine Blocks[J]. J. Mater. Sci. Technol., 2016, 32(6): 515-523.
Silicon crystals in the eutectic region of 170?ppm Sr modified AlSi7Mg0.3 alloy (Alloy 2) obtained at (a) 429 and (b) 857 Pa/s pressure, respectively.
Distributions of (a) equivalent diameter and (b) aspect ratio for eutectic Si particles estimated as function of the pressurizing speed and Sr levels. Lognormal fitting curves are drawn.
Typical pore morphology in the analysed region of the 90?ppm Sr modified AlSi7Mg0.3 alloy (Alloy 1): (a) shrinkage porosity and (b) gas porosity. The micrographs refer to a casting produced with 0.035?MPa holding pressure.
