Abstract

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.
