Subject: Structure of scandium and energy absorbing application

Hi!

In my search for Scandium and it's properties and apps, i first found out (periodic table of elements) that pure Sc has a FCC (face centered cubic) structure, but another book was talking about a HCP (hexagonal close pack) structure.
I oresume Fcc is correct for the pure metal, but does anyone know what it's stucture in alloy is?

Secondly, i'm searching for evergie absorbing materials. A material with a FCC structure has a large deformable rate, but Sc only has an ultimate tensile stress of 255 MPa and an elongation of 8 %.
I am wondering what Sc those properties are of Sc-alloy's or Al alloy containing SC (like for instance Easton's Sc7000)

Thanx!
Coen
