Phase equilibria at 1473Â K in the ternary Al-Cr-Ti system

► Phase equilibria in the Al-Cr-Ti system were studied up to 75 at.% Al at 1473 K. ► Formation of a continuous solid solution in the β phase was confirmed. ► Extended homogeneity range of the τ, γ-TiAl and (Al8Cr5)h phases were measured. ► Ternary extension of the C14 Laves phase was determined as 8.3 at.% Al.
