Effect of the Annealing Temperature and Constant Magnetic Field on the Decomposition of Quenched Beryllium Bronze BrB-2

Research Progress of Magnetic Field Regulated Mechanical Property of Solid Metal Materials

“…The changes of microhardness of the alloy was mainly due to the magnetic field affecting the number and distribution of θ phase precipitation. Diamagnetic beryllium bronze alloy, which had been solid solution treatment, was aged in the constant magnetic field of 0.7 T [16][17][18][19], and its microhardness changes are shown in Figure 2. It can be found that the microhardness of beryllium bronze alloy decreases basically (in Figure 2a-c), and the microhardness of Cu-1.6Be alloy decreases by 25.0% at most after magnetic field treatment.…”

It can be found that the microhardness of beryllium b creases basically (in Figure 2a-c), and the microhardness of Cu-1.6Be all 25.0% at most after magnetic field treatment.…”

“…According to the above research contents [11][12][13][14][15][16][17][18][19][20][21], the changes in microhardness of magnetic field-assisted heat treatment of aluminum and aluminum alloy, beryllium-bronze alloy, and titanium alloy compared with that without magnetic field are sorted into Table 1. It can be seen from Table 1 that the magnetic field can significantly change the hardness of the alloy during metal heat treatment assisted by a magnetic field.…”

“…After applying the magnetic field, the microhardness of beryllium bronze alloy containing Ni and aluminum alloy containing Fe showed a different trend from that of other alloys without adding Ni or Fe whether this phenomenon is related to the ferromagnetic Fe and Ni element, and the influence of ferromagnetic elements on the properties of alloys with paramagnetic or diamagnetic base, which is worth further study. According to the above research contents [11][12][13][14][15][16][17][18][19][20][21], the changes in micro magnetic field-assisted heat treatment of aluminum and aluminum alloy, bronze alloy, and titanium alloy compared with that without magnetic field into Table . 1. It can be seen from Table 1 that the magnetic field can significa the hardness of the alloy during metal heat treatment assisted by a magnetic f ticular, magnetic field-assisted annealing can significantly improve the plas 6.0Al-4.4V alloy prepared by selective laser melting process.…”

“…The magnetic field could refine grain inside the material, and grain refinement was also related to the dislocation. According to the variation law of grain and dislocation characteristics of aluminum alloy [19] treated by magnetic field assisted tensile treatment, the grain refinement of materials was affected by dislocation characteristics to a certain extent. As shown in Figure 8, under the magnetic field treatment, the movement activity of dislocations was enhanced, proliferation began, and some dislocations accumulated at grain boundaries.…”
