Patent number: 9440283Abstract: A process for hot shaping a workpiece of metal or an intermetallic compound at a temperature of higher than about 1000° C. The method comprises at least partially coating the surface of the workpiece with a coating agent that comprises an oxide phase and an additive and/or an adhesive before processing the workpiece into a formed body or a rolling product. A coating agent for reducing the heat emission from the workpiece comprises a predominant amount of an oxide phase. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.Type: GrantFiled: August 31, 2012Date of Patent: September 13, 2016Assignee: BOEHLER SCHMIEDETECHNIK GmbH & CO. KGInventors: Karin Rockenschaub, Wilfried Marketz

Patent number: 8888461Abstract: A material for a gas turbine component, to be specific a titanium-aluminum-based alloy material, including at least titanium and aluminum. The material has a) in the range of room temperature, the ?/B2-Ti phase, the ?2-Ti3Al phase and the ?-TiAl phase with a proportion of the ?/B2-Ti phase of at most 5% by volume, and b) in the range of the eutectoid temperature, the ?/B2-Ti phase, the ?2-Ti3Al phase and the ?-TiAl phase, with a proportion of the ?/B2-Ti phase of at least 10% by volume.Type: GrantFiled: October 18, 2008Date of Patent: November 18, 2014Assignees: MTU Aero Engines GmbH, Montanuniversitaet Leoben, Boehler Schmiedetechnik GmbH & Co.

Patent number: 8864918Abstract: A method for producing a component of a titanium-aluminum base alloy comprising hot isostatically pressing the alloy to form a blank, subjecting the blank to a hot forming by a rapid solid-blank deformation, followed by a cooling of the component to form a deformation microstructure with high recrystallization energy potential, thereafter subjecting the component to a heat treatment in the range of the eutectoid temperature (Teu) of the alloy, followed by cooling in air, to form a homogeneous, fine globular microstructure composed of phases GAMMA, BETA0, ALPHA2 and having an ordered atomic structure at room temperature. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.Type: GrantFiled: May 3, 2011Date of Patent: October 21, 2014Assignees: Boehler Schmiedetechnik GmbH & Co. KG, MTU Aero Engines GmbHInventors: Helmut Clemens, Wilfried Wallgram, Martin Schloffer

Patent number: 8828160Abstract: Method for producing a forging from a gamma titanium aluminum-based alloy. The method includes heating at least a portion of a cylindrical or rod-shaped starting or raw material to a temperature of more than 1150° C. over a cross section of the at least a portion. The at least a portion corresponds to points at which the forging to be shaped has volume concentrations. The method also includes deforming the at least a portion through an applied force to form a biscuit having different cross sectional areas over a longitudinal extension of the biscuit, and finishing the forging through a second heating to a deformation temperature and at least one subsequent step.Type: GrantFiled: June 3, 2010Date of Patent: September 9, 2014Assignee: Boehler Schmiedetechnik GmbH & Co. KG.Inventors: Sascha Kremmer, Heinz Romen-Kierner, Wilfried Wallgram
