Al-Cr-Sc (Aluminum-Chromium-Scandium)
Source abstract
Abstract
The Al-Cr phase diagram by [2000Mah] depicts a number of intermediate phases with significant ranges of homogeneity: CrAl7 (V7Al45-type monoclinic), Cr2Al11 (CrAl5-type monoclinic), CrAl4 (CrAl4-type monoclinic), Cr2Al (MoSi2-type tetragonal), and an unconfirmed lowtemperature phase X at 75 at.% Cr. Between 30 and 41 at.% Cr, five phases have been reported: aCr4Al9, bCr4Al9, cCr4Al9, aCr5Al8 and bCr5Al8, with no well-established phase boundaries between them [2000Mah]. The Al-Sc phase diagram [1999Cac] depicts the following intermediate compounds: ScAl3 (L12, AuCu3-type cubic), ScAl2 (C15, MgCu2-type cubic), ScAl (B2, CsCl-type cubic), and Sc2Al (B82, Ni2In-type hexagonal). There are no intermediate phases in the Cr-Sc system. (Cr) and (bSc) solidify as a eutectic mixture at 1090 C [Massalski2].
