A method in a pressing arrangement is disclosed. The pressing arrangement comprises a pressure vessel arranged to hold pressure medium therein during use of the pressing arrangement, the pressure vessel including a treatment region therein, wherein the treatment region is arranged to accommodate at least one article. The pressing arrangement is arranged so that pressure medium can enter and exit the treatment region. The pressing arrangement comprises at least one controllable pressure medium supplying device configured to transport pressure medium during a cooling phase from another region in the pressing arrangement to the treatment region, wherein the temperature of the pressure medium in the other region is lower than the temperature of the pressure medium in the treatment region during at least part of the cooling phase. At least one value indicative of at least one temperature in the pressure vessel is obtained. Based on the at least one value indicative of at least one temperature in the pressure vessel, at least one operational parameter of the at least one controllable pressure medium supplying device is adjusted, whereby the pressure medium supplying rate of the at least one pressure medium supplying device is adjusted. A pressing arrangement in which the method may be carried out is also disclosed.

A pressing arrangement for treatment of articles by hot pressing includes a pressure vessel including a furnace chamber and a furnace to hold the articles. A fan circulates a pressure medium within the furnace chamber, and enhances an inner convection loop at a load compartment. The inner convection loop pressure medium has an upward flow through the load compartment, and a downward flow along a peripheral portion of the furnace chamber. A flow generator generates a flow of pressure medium into the load compartment downstream the fan to enhance the inner convection loop. The flow is generated by transporting the pressure medium upwards from a space below a bottom insulating portion and above a bottom end portion, and by injecting the pressure medium into the load compartment downstream the fan to enhance the inner convection loop.

An apparatus and a method for treating an object manufactured from a material having a defined melting temperature, by subjecting the object to hot isostatic pressing to reduce porosity and increase a density thereof. The method comprises arranging the object in a pressure chamber interior cavity, submerged in a liquid partially filling the cavity, heating the liquid to a below melting temperature, pressurizing the liquid by pressurizing gas above a liquid surface in the cavity, then moving the object out of the liquid, but still within the cavity, subsequently heating the liquid to an above melting temperature, and resubmerging the object in the liquid. Subsequently, the object is withdrawn from the liquid and moved above the liquid. The apparatus comprises the pressure chamber, a movable object support in the cavity, a liquid heater, and a gas inlet and outlet selectively introducing gas into and venting gas from the cavity.

A press base may include a piston cavity formed in the press base and a piston cavity sleeve positioned in the piston cavity. The piston cavity sleeve may include a wall having an outer surface and an inner surface opposite the outer surface. The piston cavity sleeve may further include a floor having an upper surface and a lower surface opposite the upper surface. An outer radius may be formed at a juncture of the outer surface of the wall and lower surface of the floor and an inner radius may be formed at a juncture of the inner surface of the wall and upper surface of the floor. The inner radius may exhibit a radius of curvature that is greater than a radius of curvature of the outer radius.

A canister for hot isostatic pressing is disclosed including a body arranged to define a cavity for containing a powder arranged to be subjected to hot isostatic pressing; and an opening defined in the body through which a powder can be inserted into the body, and the opening being closeable so as to seal the canister for hot isostatic pressing; wherein the body comprises a weakened area, the weakened area defining a part of the body which is designed to dissolve in acid faster than the rest of the body.

A sputtering target that includes at least two consolidated blocks, each block including an alloy including molybdenum in an amount greater than about 30 percent by weight and at least one additional alloying ingredient; and a joint between the at least two consolidated blocks, the joint being free of any microstructure due to an added bonding agent (e.g., powder, foil or otherwise), and being essentially free of any visible joint line the target that is greater than about 200 m width (e.g., less than about 50 m width). A process for making the target includes hot isostatically pressing, below a temperature of 1080 C., consolidated perform blocks that may be surface prepared (e.g., roughened to a predetermined roughness value) prior to pressing.

A structure is provided. The structure defines a first direction, a second direction, and a third direction, the three directions orthogonal to each other. The structure includes a first section, a second section, and a third section. The first section includes a plurality of unit cells joined together, wherein the first section has a first average tensile strength and a first average crack growth resistance. The second substantially solid section is within and surrounding each unit cell of the plurality of first section unit cells, wherein the second section has a second average tensile strength and a second average crack growth resistance, the second average tensile strength different from the first average tensile strength and the second average crack growth resistance different from the first average crack growth resistance. The third section surrounds the first section and the second section.

A containment for use in hot Isostatic pressing, the containment comprising a body formed from sheet material and fused together along its longitudinal length using a backing strip on the outside of body. Also a containment with a body and top and bottom caps diffusion bonded upon hot isostatic pressing, a containment with a gas purge inlet and outlet and an apparatus for vacuum degassing are disclosed.

An improved method of forming components by hot isostatic pressing (HIP) involves making a can for the HIP process from a ceramic mold, reducing the need for welding & machining in the production of the can.
