Abstract

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 Subsequently, the object is withdrawn from the liquid and moved above the liquid.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.
