Summary:The invention discloses a multiplex heat treatment method for a Cu-12 percent Fe alloy, which comprises the following steps: putting raw materials of 12 mass percent of industrial pure iron and the balance of electrolytic copper into a vacuum induction furnace, heating to 1,400 DEG C to melt under barometric pressure of lower than 0.1Pa, electromagnetically stirring uniformly, standing for 2 to 3min, degassing, introducing Ar in the furnace to 30kPa, and casting into a rodlike cast ingot with the diameter phi of 20.0mm; and performing heating, heat preservation and water cooling on the cast ingot in a vacuum heat treatment furnace at three stages, heating the cast ingot in the heat treatment furnace in a temperature rise rate of average 10 DEG C/min to the aging temperature, preserving heat and cooling in air. The multiplex heat treatment method has the advantages of simply and flexibly controlling parameters, combining homogenization, solution and aging heat treatment of Cu-12 percent of Fe, effectively elim
