A method for producing a metal ingot by using an electron-beam melting furnace having an electron gun and a hearth that accumulates a molten metal of a metal raw material, wherein the metal raw material is supplied to the position on a supply line disposed along a second side wall of the hearth that accumulates the molten metal of the metal raw material. A first electron beam is radiated along a first irradiation line that is disposed along the supply line and is closer to a central part of the hearth relative to the supply line on the surface of the molten metal, wherein a surface temperature (T2) of the molten metal at the first irradiation line is made higher than an average surface temperature (T0) of the entire surface of the molten metal in the hearth.

Methods for creating a cast component, along with the resulting cast components, are provided. The method may include heating a mold having a cavity therein; supplying a first molten metal material into the cavity of the mold such that the first molten metal material is directed to a first portion of the cavity of the mold; supplying a second molten metal material into the cavity of the mold such that the second molten metal material is directed to a second portion of the cavity of the mold, wherein the first molten metal material is compositionally different than the second molten metal material; and thereafter, allowing the first molten metal material and the second molten metal material to form the cast component.

Cast components are provided that include a first section comprising a first metal material and having first grains with a first average grain size and a second section comprising a second metal material and having second grains with a second average grain size.

The present invention relates to an arrangement for low-pressure casting of refractory metals, with a furnace chamber with one or a plurality of gas supply openings (6) and gas outlet openings (7), and a riser pipe (8) through a cover (5) of the furnace chamber, a melting container (3, 12) for the refractory metals arranged in the furnace chamber, and a heating device for heating the refractory metals in the melting container (3, 12). In the proposed arrangement, the melting container (3, 12) is formed as an exchangeable insert for a receiving mould (2) supporting the melting container (3, 12), which is arranged in the furnace chamber, wherein a thermally insulating layer (4, 17) is formed between the receiving mould (2) and the melting container (3, 12), or is integrated into the melting container (3, 12). With the proposed arrangement, a quick and easy exchange of the melting container for different alloys can also be carried out in the low-pressure casting of refractory metals.

A method includes moving a first part along a movement path. The method also includes introducing drops of a liquid metal onto the first part using a three-dimensional (3D) printer. The drops of the liquid metal solidify to form a second part that is joined to the first part. The method also includes mechanically joining the second part to a third part.

The disclosure relates generally to mold compositions and methods of molding and the articles so molded. More specifically, the disclosure relates to mold compositions, intrinsic facecoat compositions, and methods for casting titanium-containing articles, and the titanium-containing articles so molded.

A vehicle is adapted to sense a condition of use in which a maximum speed control speed is reduced. The condition of use may be indicated by a sensor of the vehicle, or selected according to the kind of terrain across which the vehicle is travelling. Selection of terrain type may be manual or automatic, and may enable a selection of sensors appropriate to the terrain type. A vehicle driver may select a speed control speed lower than the permitted maximum.
