Abstract
The invention relates to a method for the treatment of an alloy based on titanium aluminide. The method comprises the following steps, during which no hot isostatic pressing is carried out: obtaining a semi-finished product (7) produced by centrifugal casting, then heat treating the semi-finished product in order to obtain an alloy microstructure comprising gamma grains and/or lamella grains (alpha2/gamma).
