摘要
The invention relates to a method for the capsuleless deformation of Ϝ-TiAl materials at temperatures of between 900 °C and 1400 °C. The inventive method is characterised in that the deformation is carried out by means of deformation tools consisting of particle-reinforced X5Si3 or XSi2 materials, wherein X represents Mo, Nb, Ta, W, Hf, V, Zr, Ti, Cr, Re or Fe, and the particle reinforcement constituents are formed by means of chemical reactions in situ, during the sintering process, from precursor materials which have been added, before the activation process, to the activated powder mixtures used for producing the X5Si3- or XSi2- active ingredients.
