Method of Diffusion Bonding in a Vacuum

摘要

The object of the invention is a method of diffusion welding in a vacuum in accordance with the patent No. 112460 which intensifies the diffusion process by a cyclic raising and lowering of the temperature of heating of the material within the limits of =30 to 100C above and below the temperature of the phase transformation, keeping within the limiting temperatures and repeating this cycle until one is sure of phase transformation of not less than 10 to 20% of the grain of the alloy in the course of each cycle.
