Description

technical field

[0001] The invention relates to a method for preparing a titanium alloy / TiAl alloy composite plate. Background technique

[0002] TiAl alloy (or TiAl intermetallic compound) has low density, high specific strength and specific elastic modulus, and can still maintain high enough strength and stiffness at high temperature, and it also has good creep resistance and oxidation resistance, etc. With outstanding features, it has broad application prospects in the fields of aerospace, aviation and automobiles. The service temperature of TiAl alloy can reach 700-900Β°C. TiAl alloy sheet is the most urgently needed material in the practical process of this material, but the shortcomings of TiAl alloy sheet, such as low room temperature plasticity and poor processability, seriously hinder the application of the sheet. The patent application number is 200510009906.0, the publication number is CN1672918A, the publication date is September 28, 2005, and the invention pate...
