Joining Technologies for Gamma Titanium Aluminide Castings: Final Report CRADA No. TC-1088-95
Abstract
The purpose of this project was to assist the Paton Electrical Welding Institute in developing the technology and brazing consumables required to join and repair gamma-TiAl castings. This technology was critical to the introduction of gamma-TiAl components into the next generation of lightweight, fuel-efficient aircraft engines. Pratt & Whitney and other engine manufacturers were highly interested in this technology and targeted this material in the low-pressure turbine sections of their engines. Improvements in weldability were required prior to implementing this material. The CRADA developed the capability to join gamma-TiAI couples and repair gamma-TiAl castings using methods that allow full utilization of the parent material properties.
