Popis:	The structure, the strength at high temperatures, and the fracture toughness of the composites fabricated under various conditions of diffusion welding of stacks of Nb foils with coatings made of a mixture of Nb, Ti, Mo, Si, ZrH2, Cr, and Al powders are studied. The strength in the temperature range of 1100–1300°C changes from 490 to 350 MPa, the fracture toughness at room temperature is 15.6 MPa m1/2, and the creep resistance determined in 100-h tests at a residual strain tolerance of 1% at 1150°C is 90 MPa.
