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 Si2Hf-type phase.

    In hot rolling, a metal is given its final shape by thermo-plastically deforming the original stock. The formation of the temperature profile therefore has a complex history. In this process, it is essential to know the temperature distribution within the strip along the thickness and length of...
