研究了Co70Fe6Ni13B4Si7（71KHCP）非品合金磁性能的时间稳定性，是根据历时13年当中每年对其初始磁导率测量的结果来评价的．利用光化学铣切法由这种非品合金带材制成环状试样，其中一半试样经过300℃×1h真空退火，其余一半试样则保持原始状态（熔体快淬）．还有一部分试样（
The temporal stability of the magnetic properties of Co70Fe6Ni13B4Si7 (71KHCP) non-alloyed alloys was investigated based on the annual magnetic permeability measurements over 13 years. Ring specimens were made from this non-alloyed strip by photochemical milling. Half of the specimens were vacuum annealed at 300 ℃ for 1 hour, and the rest of the specimens remained as they were (melt quenched). There are some samples (
