2 as layers in alternative embodiments the component 10 has a layer structure having a sequence of areas with metallic materials where the linear expansion coefficients meet the following conditions relatively to one another hence a finer graduation of the material properties is possible with more than two areas i 2 3 4 5 in these ways it is for example possible to build up a kind of layer structure with three or more areas 1 2 of differing materials it is not essential here that the thickness of the layers is identical over the entire layer system in any event the result is a layer system with graduated properties i e properties matched to one another fig1 b shows two areas 1 2 of which the material properties are matched to one another all areas 1 2 here can be built up by a generative laser process alternatively at least one first area 1 2 can represent a substrate that is for example a casting the second area 2 1 can then be applied to this substrate using a generative laser process with this embodiment the material properties in particular the expansion coefficients of the casting and the applied area must then be matched to one another according.
