Abstract: A method of fabricating a superplastically formable strip or a superplastically formable foil from TiAl6V4 with a thickness of no more than 0.9 mm, preferably less than or equal to 0.5 mm, comprises the steps: a) hot rolling a sheet metal made of TiAl6V4; b) thermal pre-treatment of the hot-rolled sheet metal at a temperature between 650 and 850° C.; and c) cold rolling the hot-rolled and thermally pre-treated sheet metal at a forming rate of at least 30%, wherein the forming rate per single pass amounts to between 1 and 15%, to form a strip or a foil with a thickness of no more than 0.9 mm, wherein the cold-rolled strip or the cold-rolled foil is not annealed.

Abstract: A heat insulation material based on ceramic material includes a top layer containing BaZrO3 and Y2O3 doped ZrO2. A heat insulation material preferably consists of at least one adhesion promotion layer, at least one intermediate layer arranged thereon and a top layer arranged thereon, with the adhesion promotion layer consisting of MeCrAlY, where Me is nickel and/or cobalt, the intermediate layer consists of Y2O3 doped ZrO2 and the top layer consists of 15 to 25% by weight BaZrO3 and 75 to 85% by weight Y2O3 doped ZrO2. A method of coating a substrate with a heat insulation material includes the step of applying an aforesaid top layer to an optionally coated substrate by a thermal spray method or an electron beam method, in particular an EB-PVD method.
