A method for producing a layer composite includes providing a plurality of layers, each layer comprising a material comprising at least one of a metal, a metal alloy, and at least one layer comprising a metal which forms a solid solution with a refractory metal. Each layer of the plurality of layers is placed in an alternating manner one onto another so as to form a layer stack and so as to form contact surfaces. The plurality of layers in the layer stack are diffusion welded in a non-oxidizing atmosphere at a temperature of between 0.4 times and 0.9 times a melting temperature of the metal and at a pressure comprising a directional pressure component oriented orthogonally in relation to the contact surfaces. A magnitude of at least one of the pressure and the temperature change during the diffusion welding.
