Various embodiments disclosed relate to an alloy. The alloy includes elemental silver. The alloy further includes a metal oxide phase in the elemental silver. The metal oxide phase includes a wetting agent layer that coats the metal oxide phase.

The invention relates to a forming method of an alloy comprising predominantly Ti or nearby stage, comprising the steps of: Preparation of a homogeneous mixture of particle powder comprising micrometric particles of pure Ti and nanoscale particles of at least one additional element or compound promoting the beta phase of the Ti during its cooling from its phase transition temperature. exposing said particle powder mixture to a focused energy source that is selectively heat at least a portion of a bed of said homogeneous powder mixture at a temperature between 850 and 1850 C. cooling of the part having undergone this exposure with conservation of the phase b of the Ti.

The present invention provides an aluminum hybrid metal matrix composite including cerium and graphite. The aluminum-cerium intermetallic is stable at temperatures up to a melting point of aluminum and graphite provides in situ lubrication. This stability is advantageous in applications such as cylinder liners and other applications where strength and stiffness at elevated temperatures are required.

The present disclosure relates to a wear part having high wear resistance and strength and a method of making the same. The wear part is composed of a compound body of cemented carbide particles cast with a low-carbon steel alloy. The low-carbon steel alloy has a carbon content corresponding to a carbon equivalent Ceq=wt % C+0.3(wt % Si+wt % P) of about 0.1 to about 1.5 weight %. The wear part could include a body with a plurality of inserts of cemented carbide particles cast into a low-carbon steel alloy disposed in the body. Each of the plurality of cemented carbide inserts are coated with at least one layer of oxidation protection/chemical resistant material. The plurality of inserts are directly fixed onto a mold corresponding to the shape of the wear part. The cemented carbide inserts are then encapsulated with the molten low-carbon steel alloy to cast the cemented carbide inserts with the low-carbon steel alloy.

The present invention relates to the composition and production of an engineered degradable metal matrix composite that is useful in constructing temporary systems requiring wear resistance, high hardness, and/or high resistance to deformation in water-bearing applications such as, but not limited to, oil and gas completion operations.

A method including: submerging a ceramic preform (10) in a layer (12) of powdered superalloy material (14), wherein the preform defines a desired shape of a channel (60, 62, 64, 78) to be formed in a layer (42) of superalloy material; melting the powdered superalloy material around the preform without melting the preform; and cooling and re-solidifying the superalloy material around the preform to form the layer of superalloy material with the preform defining the shape of the channel therein.
