镍基磁致伸缩合金在研制新型磁致伸缩合金时必须遵循以下条件：高的磁致伸缩特性要提高力学性能和电阻，同时降低声速。磁致伸缩特性之中有两个参数要求最大值：饱和磁致伸缩（亦即在静态磁化时试样可达到的最大尺寸相对变化）λｓ和动态机电耦合系数κ（决定交流电能转变... Nickel-based magnetostrictive alloys in the development of new magnetostrictive alloy must follow the following conditions: High magnetostrictive properties to improve the mechanical properties and resistance, while reducing the speed of sound. Two of the magnetostrictive properties require the maximum value: the saturation magnetostriction (ie, the maximum relative change in the size of the sample that can be achieved during static magnetization) λs and the dynamic electromechanical coupling coefficient κ (which determines the AC power conversion ...
