Abstract
A composite structure including a substrate and a heat protection element on the substrate, wherein the heat protection element includes a quasicrystalline aluminium alloy of one or a number of quasicrystalline phases which are either quasicrystalline phases in the strict sense, or approximating phases, wherein the quasicrystalline phases exhibit a thermal diffusivity, measured at ambient temperature, lower than 2.5×10,m,/s, and a thermal diffusivity measured in the temperature range 650-750° C. which does not exceed the thermal diffusivity measured at ambient temperature by more than a factor of 3, and wherein the quasicrystalline aluminum alloy includes Al,Cu,Co,X,Y,T,I,, wherein X represents at least one metalloid selected from the group of B, C, Si, Ge, P and S; Y represents at least one metal selected from the group of Fe, Mn, V, Ni, Cr, Zr, Hf, Mo, W, Nb, Ti, Rh, Ru, and Re; T represents at least one rare earth; I represents unavoidable production impurities; a+b+c+d+e+f+g=100 atom %; 14≦b≦27; 8≦c≦24; 28≦b+c+e≦45; 0≦f≦4; 0≦d≦5; and 0≦g≦2.
