Determine the Conditions of Formation of Defect-Free TiAl Foil
Abstract
This report results from a contract tasking E.O.Paton Electric Welding Institute as follows: Because TiAl-base materials have relatively low density, high strength, good wear resistance, and excellent resistance to oxidation and corrosion, they are of considerable interest in the aerospace industry. In particular, the materials are prime candidates for components aircraft engines. However, the relatively low plasticity of the intermetallic compound presents challenges with respect to the fabrication of small/thin cross-section semi-finished products such as rod, sheet, foil and so on. Hence, many of the applications of the materials are limited at present. When TiAl products of are made by conventional thermomechanical processing of ingots, the formation of the mechanical and/or crystallographic texture, the segregation of impurities to grain boundaries by impurities, etc., may adversely affect the performance of the finished product.
