摘　　要：本试验针对电磁阀用FeCr软磁合金性能要求，研究了不同Cr含量以及添加元素Mo，Nb和稀土等对其性能的影响作用。结果表明，合金中Cr含量的变化，对合金的磁感应强度特别是低磁场下的磁感应强度影响显著。降低合金中的Cr含量，有益于提高合金在低磁场下的磁感应强度，有益于优化电磁阀的结构尺寸。合金中适量添加Mo，Nb和稀土等元素可以改善合金的耐蚀性能且并不会造成合金的磁性能显著降低。Effect of elements of FeCr soft magnetic alloy on the properties for solenoid valves has been investigated. The results show that a decrease of Cr content means an in- crease of magnetic flux density of the FeCr soft magnetic alloy under low magnetic field state and thus it is useful for reducing the designed size of solenoid valve. Also,additive of Mo,Nb and some rear earth elements will improve the corrosion resistant for the alloy while the mag- netic properties of the alloy are still in suitable state.
