To achieve uniform heating of metal components in all their regions, a method and device for heating metal components using electron irradiation in a vacuum chamber includes multilayer holding elements having an outer layer facing the electron radiation. The outer layer is resistant to heat and exhibits good heat-absorption properties. The holding elements also have an inner layer facing the respective metal component and exhibiting good heat-radiating properties. The holding elements are used to hold the metal components in the vacuum chamber during heating.

Method and device for heating metal components using electron irradiation in a vacuum chamber

A method for cooling metal components highly heated in a chamber includes effecting a uniform cooling of an entire metal component. The metal component has regions each with a given mass, some of the regions having a larger mass than others of the regions. Housings are provided around regions with the relatively larger masses. The regions are subjected to the inert cooling gas in a controlled manner to a differing extent based upon the mass size. The housings are individually subjected separately with the inert cooling gas. A treatment device for cooling metal components includes a reservoir for holding inert cooling gas and a chamber for receiving a metal component to be cooled. The chamber is connected to the reservoir and has a housing for each of the regions with the larger mass. Each of the housing has an inlet orifice separately connected to the reservoir.
