不锈钢纤维的铁磁性:

Ferromagnetism of stainless steel fiber:

随着纤维丝径减小，其饱和磁化强度在增大.随着纤维丝径减小,马氏体相含量在增加,其特征衍射峰强度

With the decrease of fiber diameter, the saturation magnetization increases. With the decrease of fiber diameter, the content of martensitic phase increases, and its characteristic diffraction peak strength is increased.

也明显增高。而晶粒尺寸减小到一定程度后，晶粒间的交换耦合作用使材料的剩磁增强、矫顽力下降、磁导率提高。造成奥氏体纤维具弱磁性原因可能由应力诱发的马氏体相变，奥氏体不锈钢纤维主要成份也是铁，也可能因纤维丝径越小，其组织中的铁元素更接近铁磁性的空间状态。在一定范围内，随着丝径变小，磁性增大，

It was also significantly higher. When the grain size is reduced to a certain extent, the exchange coupling effect between the grains makes the remanence of the material, the coercivity and the permeability increase. The reason for the weak magnetic property of austenitic fiber may be the martensitic transformation induced by stress. The main component of austenitic stainless steel is also iron, or the smaller the fiber diameter is, the more iron element in its microstructure is closer to the ferromagnetic state. In a certain range, as the diameter of the silk becomes smaller, the magnetic properties increase.

8UM纤维磁性比20UM和12UM纤维高出3-6倍，6UM-2U纤维的磁性小于8UM不锈钢纤维的磁性；

The magnetic properties of 8UM fiber are 3-6 times higher than that of 20UM and 12UM fibers, and the magnetic properties of 6UM-2U fibers are less than that of 8UM stainless steel fibers.

退火后纤维呈顺磁性。纯奥氏体相纤维磁性相对较弱，退火可使纤维组织再次转变为单一奥氏体，

The annealed fibers are paramagnetic. The magnetic properties of pure austenite fibers are relatively weak, and annealing can make the fibrous tissue change to a single austenite.

其马氏体衍射特征峰表现为减弱或消失。马氏体相纤维磁性较强，其强度超过镍基体。

The characteristic peak of martensitic diffraction is weakened or disappearing. Martensitic fiber has strong magnetic properties, and its strength is higher than that of nickel matrix.
