Embodiment 1
[0022] 1) Mn and Fe with a purity greater than 99.5wt% are used as raw materials, weighed at an atomic percentage of 40:60 and placed in a quartz crucible, and the vacuum degree of the vacuum chamber is adjusted to 5×10 -2 ~2×10 -3 Pa, into high-purity argon as protective gas, intermediate frequency induction heating and melting, and cast in a water-cooled copper mold to form a rod-shaped Mn with a cross-section of 10mm thick × 12mm wide 40 Fe 60 alloy ingot.
[0023] 2) The smelted rod-shaped Mn 40 Fe 60 The alloy ingot was heated to 900°C in a vacuum tube furnace for 72 hours to homogenize its composition, and then slowly cooled to room temperature.
[0024] 3) For homogenized rod-shaped Mn 40 Fe 60 The alloy was cold-rolled 6 times, with a reduction of 0.5 mm each time. In order to eliminate cold work hardening, it was annealed at 300 ° C for 2 hours, and then rolled 4 times to obtain a rolling rate of 50%. 40 Fe 60 Alloy cold-rolled plate, thickness 5mm.
