Ti—Al—Nb Alloys by Thermal Explosion: Synthesis and Characterization

摘要

For products of thermal explosion in Ti—Nb—2Al, Ti—Nb—2.5A1, and Ti—Nb—3Al compacts, investigated were their morphology, phase composition, microstructure, and some physical parameters. Best homogeneity and lowest porosity were shown by the products derived from Ti—Nb—3Al compacts. The main product of thermal explosion was tetragonal γ-TiAl with a distorted lattice, tentatively a solid solution of Nb in TiAl.
