A method for bonding a first substrate and a second substrate includes: forming a protrusion at a partial region of the first substrate; measuring a position of the first substrate after the protrusion is formed in the first substrate; and bonding the first substrate and the second substrate by contacting the protrusion of the first substrate with a surface of the second substrate to form a contact region and enlarging the contact region.

The present invention relates to a tube for transporting fluids in seawater. The tube has a tubular body formed of an alloy selected from duplex stainless steel, superduplex stainless steel, a ferritic steel, a martensitic steel or a nickel superalloy and a layer configured to protect the tube from hydrogen induced stress cracking arranged on an outer surface of the tubular body. The layer is formed of an alloy having a copper content of 50-95 wt % and a nickel content of 5-50 wt %. The tube has a metallurgical bond, formed in the solid state, at an interface between the tubular body and the layer. The metallurgical bond is formed by a hot isostatic pressing process for a predetermined time at a predetermined pressure and a predetermined temperature. The present invention also relates to a method for manufacturing a tube. The present invention also relates to a subsea arrangement.

Lithium anodes that include lithium metal sheets or foils welded to current collectors are described with processes for their formation. One example is a lithium metal anode for use in a battery that includes a current collector carrying proximal lithium metal layers that carry distal lithium metal layers. The proximal lithium metal layers having thicknesses of about 100 nm to about 25 ?m and having greater than about 99.5 wt. % lithium, the distal lithium metal layers having thicknesses of about 10 ?m to about 200 ?m and having greater than about 90 wt. % lithium. Notably, the proximal and distal lithium differ in their average grain sizes with the distal average grain size but at least 1.5 times the size of the proximal average grain size.

A method for the manufacturing of an object. The method includes receiving a desired alloy composition for the object, depositing a plurality of foils in a stack to form the object, applying heat to the stack at a first temperature to bond the plurality of foils to each other, and applying heat to the stack at a second temperature to homogenize the composition of the stack. The homogenized stack has the desired alloy composition.

A method for forming a metal flow module includes forming a flux retention feature on a first major surface of a first metal plate and then applying flux to the first major surface. The flux retention feature is configured to retain the flux at least in part on the first surface. The method further includes positioning a second major surface of a second metal plate against the first major surface of the first metal plate. The second metal plate has one or more flow channels defined at least in part in the second major surface. The flux is positioned between first contacting portions of the first and second major surfaces. The method further includes heating the first and second metal plates in a non-oxidizing atmosphere to thermally bond the first contacting portions.

A method for manufacturing a shaft, whereby a hollow shaft in which linking members are joined at both ends of a cylindrical member (a pipe member) can be manufactured more efficiently. A method for manufacturing a shaft in which linking members are provided to end parts of a cylindrical member, wherein the method comprises: a preparation step for preparing the cylindrical member, in which male threaded portions are formed at the end parts; a screwing step in which the linking members, which have female threaded portions to be screwed onto the male threaded portions, are screwed onto the male threaded portions; and a diffusion-joining step in which opposing end surfaces of the linking members and the cylindrical member are heated in a state of being pressed against each other by the tightening produced by the screwed-on linking members, and the opposing end surfaces are diffusion-joined.
