Abstract The effect of simultaneous magnetic field and deep cryogenic treatment on the structure and mechanical properties of aluminum brass subjected to deep cryogenic treatment was investigated. The results show that the static magnetic field can further improve the strength and toughness of the aluminum-brass. When T=24 h, the test samples named MDCT (magnetized-deep cryogenically treated samples ) have the best tensile strength (602.5 MPa) and elongation (7.2%) which increase by 6.4% and 53.2% compared with the initial sample, and increase by 3.1% and 28.6% respectively compared with DCT (deep cryogenically treated samples). The reason for the property improvement is that during the reversion of test sample from deep cryogenic condition to room temperature, the dynamic recrystallization occurs, which play an important role in grain refinement strengthening effect. At the same time, based on the magnetoplasticity effect, it is easier for the dislocation to move which is beneficial to improve the capability of elongation and plastic deformation. In addition, under the condition of static magnetic field, the conversion rate of α-phase to β-phase in Al-brass has been reduced, and the conversion rate of γ-phase increased. Besides, the average grain size of MDCT is bigger than DCT.
