Summary: | Ag/Ni Multilayers were prefabricated by Accumulative Roll-Bonding(ARB),with an average layer thickness ranging 20-100 nm.The Ag-45.8wt%Ni alloys were annealed under 31.2T high magnetic field to study its effect on microstructure and performance.31.2T high magnetic field significantly suppressed the coarsening of layer structure during annealing,the magnetic field parallel to the layer has a larger suppression effect.As the annealing temperature increased,the resistivity of Ag/Ni multilayers increased,and the hardness decreased.The case of perpendicular high magnetic field has the largest resistivity and the largest hardness,compared with die other two cases.The hysteresis loops shows that Ag-Ni has a hard ferromagnetic property.The case of parallel magnetic field has the largest coercivity about90Gs. |
