对“FINEMET”(Fe73 5Cu1Ni3 Si13 5B9)的设计原理作了分析和讨论。同时介绍了FINEMET在激波作用之下 ,其合金中最能体现其设计思想的Cu、Nb等元素的主要作用却失效了。
The design principle of FINEMET (Fe73 5Cu1Ni3 Si13 5B9) is analyzed and discussed. At the same time, it is introduced that under the action of shock wave, the main effect of FIN, Cu, Nb and other elements which can best embody its design idea in the alloy has failed.
