Abstract: A composite body and a method for producing an integrally cast composite body, which includes at least two zones. A first zone is substantially formed of metal material, and, a second zone additionally includes a non-metallic reinforcing material, such as cement carbide. The composite body is particularly useful for producing products which have at least one wear resistant zone or surface.

Abstract: A method for producing a cylindrical hollow body (20) made of aluminum, an aluminum alloy, or a light metal alloy, includes casting a hollow body (20) such that the hollow body (20) has an inner and an outer lateral surface (21, 22) and two axial end faces. The method also includes, during the casting process, making at least one defined notch (35, 35′) into one or more of the inner lateral surface (21), the outer lateral surface (22), and the two axial end faces.

Abstract: An investment powder which is safer than conventional powders comprising tricalcium phosphate, and being substantially or entirely free of free silica in the respiratory portion yet providing an overall expansion at 750° C. of 1% or higher sufficient to prevent mould cracking during casting. A method of making a casting comprising forming a slurry by mixing a gypsum bonded investment powder with water, pouring the slurry into a stainless steel flask around a low melting point material model, allowing the slurry to set to define a mould, heating the mould to burn out the model and casting material into the mould wherein the stainless steel flask consists of a 400 series martensitic stainless steel.

Abstract: A method for manufacturing a roll mantle or roll body for a roll line of a continuous casting apparatus that has a shaft includes casting a metal to form the roll mantle or roll body such that the roll mantle or roll body includes at least one internal channel. The roll mantle or roll body has a first end region, a second end region and a central region between the first end region and the second end region, the central region extending along at least 50% of a length of the roll mantle or roll body, and the internal channel may be formed in the central region. The internal channel may also include a pattern or projection.

Abstract: A casting core for an airfoil according to an example of the present disclosure includes, among other things, a first portion extending in a first direction and corresponding to a first cavity of an airfoil. The first portion defines a reference plane along a parting line formed by a casting die. The first portion defines a plurality of grooves corresponding to a plurality of trip strips of the airfoil. Each of the plurality of grooves defines a respective groove axis, and the plurality of grooves are distributed in the first direction along a first side of the reference plane such that one or more of the groove axes are oriented with respect to a pull direction of the casting die. A method for fabricating a gas turbine engine component is also disclosed.

Abstract: Provided is a titanium cast product made of commercially pure titanium, the titanium cast product being produced by electron-beam remelting or plasma arc melting, comprising: a melted and resolidified layer in a range of 1 mm or more in depth at a surface serving as a surface to be rolled, the melted and resolidified layer being obtained by adding one or more kinds of βstabilizer elements to the surface and melting and resolidifying the surface. An average value of β stabilizer element(s) concentration in a range of within 1 mm in depth is higher than βstabilizer element(s) concentration in a base material by, in mass %, equal to or more than 0.08 mass % and equal to or less than 1.50 mass %. As the material containing the β stabilizer element, powder, a chip, wire, or foil is used. As means for melting a surface layer, electron-beam heating and plasma arc heating are used.
