Abstract (en)
[origin: US2015218675A1] The present invention relates to a TiAl alloy for use at high temperatures having the main constituents titanium and aluminum and having a proportion of aluminum of greater than or equal to 30 at. % and a matrix composed of β phase and precipitates of ω phase embedded in the matrix, with the β phase and the ω phase together making up at least 55% by volume of the microstructure, and also a process for the production thereof and the use thereof.
