A cylinder head assembly for an internal combustion engine includes a cast cylinder head defining a combustion chamber and fabricated from a first material, and an internal support structure at least partially encapsulated within the cast cylinder head. The internal support structure is fabricated from a thermal strain and fatigue resistant second material, different from the first material, such that during engine operation, thermal and mechanical loads are transferred to the internal support structure to reduce combustion chamber displacement. The internal support structure and the cylinder head are bonded via a hot isostatic pressing (HIP) process to eliminate internal porosity and gaps therebetween.

Embodiments of golf club face plates with internal cell lattices are presented herein. Other examples and related methods are also disclosed herein.

A method of eliminating dissimilar metal welds has been disclosed. The method includes the steps of providing a first part having a first alloy composition; providing a second part having a second alloy composition different from the first part; connecting a containment structure to the first part; pouring a powder into the containment structure such that the powder is in contact with the first part; positioning a portion of the second part in the containment structure such that the second part compresses the powder between the first and second parts; and performing hot isostatic pressing (HIP) to consolidate the powder and join the first and second parts together.

Systems and methods form induction rotors by performing isostatic pressing (HIP) to weld clad to a shaft, which allows for scaling the manufacturing of solid steel rotors, as compared to conventional techniques. In examples, the rotors are designed for high-speed motors and may include recessed short circuit rings and/or end rings. An exemplary process molds an alloy powder into cladding such that heretofore unachievable rotor designs are achievable according to systems and methods described herein. In examples, a thin source-layer is introduced to welding zones, thereby enriching and strengthening the resulting joint at welding zones. The source-layer may be introduced by adding an intermediate layer comprising the source material between the materials being welded. The reduced alloy-depletion welding disclosed herein strengthens the welding area joints and provides for the manufacture of component designs, which were previously unachievable due to alloy-depletion weaknesses and environmental constraints.

The invention relates to a method for manufacturing a solid metal based component. The method comprising the steps of providing a plurality of metal based sheets; arranging the plurality of metal based sheets in a stack, 5 wherein the stack comprises a first metal based sheet, a last metal based sheet and at least one intermediate metal based sheet; perimetrically sealing at least a portion of the stack forming at least one cavity inside of the stack; removing gas from said at least one cavity, and subjecting the stack to a hot isostatic pressing process for a predetermined time at a predetermined 10 pressure and a predetermined temperature so that the plurality of metal based sheets of the stack bond metallurgically to each other to form a solid metal based component. The invention further relates to a single-piece metal based component.

A TiAl alloy material for hot forging includes a TiAl alloy substrate formed of a TiAl alloy which contains 42 at % or more and 45 at % or less of Al, 3 at % or more and 6 at % or less of Nb, 3 at % or more and 6 at % or less of V, 0.1 at % or more and 0.3 at % or less of B, and the balance being Ti and inevitable impurities, an intermediate layer formed on a surface of the TiAl alloy substrate, and a titanium layer formed on a surface of the intermediate layer, wherein the intermediate layer is formed of a first layer which is formed on a side of the TiAl alloy substrate and is formed of the TiAl alloy which becomes β-TiAl at a hot forging temperature range between 1200° C. or higher and 1350° C. or lower and a second layer that is formed on a side of the titanium layer and is formed of a β-Ti material.

A disc cutter for a cutting unit used in a tunnel boring machine and a method of producing the same. The disc cutter includes an annular disc body made of a metal alloy or metal matrix composite having a first side, a second side arranged substantially opposite to the first side and a radially peripheral part. At least one metal alloy, metal matrix composite or cemented carbide cutting part is mounted in and substantially encircling the radially peripheral part of the disc body, which protrudes outwardly therefrom to engage with the rock during the mining operation. The at least one cutting part is made from a material having a higher wear resistance than the material used for the disc body. A metallic interlayer is disposed between at the least one disc body and the at least one cutting part, the elements of which form the diffusion bonds.

A device for manufacturing a plate solder according to the present invention includes a reel on which a thread solder is wound; a cutter that cuts the thread solder, provided between the reel and an end part of the thread solder extending from the reel; an aggregating part that aggregates a plurality of cut thread solders such that the plurality of thread solders are in contact with one another; and a roller that rolls the plurality of aggregated thread solders and pressure bonds them to one another to form a plate solder.
