Abstract
The aim of this work is to determine the Solid Fraction (SF) at the rigidity point (FRP)
by applying advanced thermal analysis techniques. The variation of the FRP value is important
to explain the solidification behavior and the presence or absence of defects in aluminum alloys.
As the final alloy composition plays a key role on obtained properties, the influence of major and
minor alloying elements on FRP has been studied. A Taguchi design of experiments and a previously
developed calculating method, based on the application of high rank derivatives has been employed
to determinate first the rigidity point temperature (RPT) and after the corresponding FRP for AlSi10Mg
alloys. A correlation factor of r2 of 0.81 was obtained for FRP calculation formula in function of the
alloy composition.
