不同强度交变磁场对45号钢力学性能影响研究

Effect on different intensity of alternating magnetic field on mechanical properties of 45 steel

在不同强度交变磁场作用下,对45号钢试件进行拉伸实验,结果显示:磁感应强度对45钢的力学性能有较大影响:磁感应强度越大,45号钢强度、塑性越小。这一结论为在磁场环境下工作的部件(如磁悬浮列车、航母电磁弹射器、电磁炮等)设计提供了一定的指导作用。

In different intensity alternating magnetic field, a tensile test on the right 45 steel specimen is done, the results show： the magnetic induction has great influence on the mechanical properties of 45 steel, the stronger magnetic induction intensity, the smaller 45 steel strength and plastic. This conclusion provides some guidance on the design that components working in magnetic field（ such as maglev trains, aircraft carrier electromagnetic catapult, electromagnetic gun etc）.
