Title: Distribution of Al{sub 12}Fe{sub 3}Si and (FeAl{sub 6})Si in a HIPed Al-10.71 wt. % Si casting

Abstract

An investigation on microstructural development in a hot isostatically pressed (HIPed) Al-10.71 wt. % Si casting is described. The as-cast material contained 0.006 total volume fraction of Al{sub 12}Fe{sub 3}Si and (FeAl{sub 6})Si particles but HIPing at 550 C and 68.95 MPa produced a moderate increase in this fraction, to a maximum value of 0.061 when HIPed for 120 min. Dislocations appeared to be the dominant nucleation sites for the particles in both the as-cast and the HIPed materials.
