Ti-base nanoeutectic-hexagonal structured (D019D019) dendrite composite

Ti–Fe–Sn nanoeutectic-hexagonal structured dendrite composites are prepared by arc melting and cold-crucible casting. The presence of micrometer-size hexagonal (D019D019) dendrites in the nanostructured lamellar matrix increases the strain-hardening exponent (n  ) from n=0.068n=0.068 for homogeneous eutectic to n=1.64n=1.64 for composites. Formation of profuse slip bands in the hexagonal dendrites/nanoeutectic phases indicates that dislocation-slip is the dominant deformation mechanism in these micro-nanophases.
