    Abstract: A process for forming knife blades such as for kitchen or sport knife use comprises injecting a compound including a binder and a metallic powder into a mold having a shape of the knife blade, removing a green blank from the mold and sintering the green blank to produce a sintered blank. The sintered blank is then subjected to a hot-isostatic-pressure to produce a finished blank. An insert may be placed in the mold to impose a desired feature, such as a logo or legend, on the green blank during the molding process. The mold is so configured as to changeably receive the insert so that a first series of blanks can be made using the insert, then a new insert may be emplaced to impose a different feature on succeeding blanks formed in the mold. An edge component may be placed in the mold, around which the blank is injected, to form a compound blade.

    Abstract: Material and method for the production of material with isotropic, mechanical properties and improved wear resistance and high hardness potential. Method includes producing in a powder metallurgical (PM) method a slug or ingot from a material of ledeburite tool steel alloy, and subjecting one of the slug or ingot or a semi-finished product produced from the slug or ingot to full annealing at a temperature of over 1100° C., but at least 10° C. below the fusing temperature of the lowest melting structure phase with a duration of over 12 hrs. In this manner, an average carbide phase size of the material is increased by at least 65%, a surface shape of the material is rounded and a matrix is homogenized. Method further includes subsequently processing the material into thermally tempered tools with high wear resistance occurs or into parts to which abrasive stress is applied.

    Abstract: A method of cooling a load provided in a load compartment in a furnace chamber of a furnace of a hot isostatic pressing device includes releasing hot pressure medium from the load compartment. Cool pressure medium is provided for enabling it to fall through the released hot pressure medium outside the load compartment. The thus obtained mixed pressure medium is led into the load compartment. A hot isostatic pressing device includes a load compartment having an aperture near an upper portion thereof configured to vent warm pressure medium into a region surrounding the compartment, and a conduit configured to introduce cool pressure medium into the region surrounding the compartment for mixing with the warm medium. The compartment also includes an aperture near a lower portion thereof configured to receive a mix of warm and cool pressure medium from the region surrounding the compartment.
