摘要
High density of nanobeltlike precipitates has been observed in an Al-Si-Mg-Hf-Y alloy after heat treatments. Quantitative analysis in scanning transmission electron micrscopy (TEM) shows that the precipitates contain Hf, Si, and some Al. The precipitates have an orthorhombic structure which has been revealed by high-resolution TEM and electron diffraction. The precipitates have been identified to be of the Si(2)Hf-type phase.
