ABSTRACT:
The present invention presents a method and an apparatus for heat treating a metallic material by performing hydrogen absorption in or desorption from the metallic material. The method includes the steps of recovering the hydrogen gas released from a desorption step and recycling it to a hydrogen absorbing step. Hydrogen recovering can be performed either in a device containing a hydrogen absorbing alloy or in a second heat treating furnace containing the metallic material. Various controlling devices are used to regulate the process of heat treating and recovering of hydrogen gas.
