1. A part given in figure 1 is to be made by casting.
The following alloying material compositions are considered: Al3%Si
and Al-12%Si.
a. Make two sketches showing typical solidification pattern of each of the above two alloys in a cylindrical mold (annotate clearly).
b. Make judgments on the castability of each alloy; consider the following properties fluidity, micro-porosity, alloying element macro segregation. (Give your answers for each alloy in the above sequence; justify each answer in one or two sentence.)
