非晶态合金传感器的发展

本文对近十年来国际上非晶态合金传感器的发展进行了综合评述。其中讨论了用于传感器的非晶态合金的特性,构成传感器的要素,介绍了非晶态合金传感器的分类、结构形式、实例及若干应用。按所利用的合金的磁致伸缩特性和物理效应把非晶态合金传感器分成5类:(1)利用零磁致伸缩合金制作的传感器;(2)利用超声传播效应的传感器;(3)利用应力-磁效应的传感器;(4)利用大巴克好森效应和迈悌欧锡斯效应的传感器;(5)利用电阻-应变等等其他物理效应的传感器。

ADVANCES OF AMORPHOUS-ALLOYS SENSORS

Advances of amorphous-alloy sensors are reviewed.Advantageous properties of amorphous alloy as the sensors material and the basic principle of the constitution of amorphous-alloy sensors are discussed.The classification,constitutional form,practical examples and application of amorphous-alloy sensors are introduced.According to the utilized physical effect,the amorphous-alloy sensors having been developed by this time are classified into five groups;(1)sensors altilizing ze-roomagnetostriction alloy;(2) sensors ultilizing the ultrasonic propagation effect;(3) sensors ul-tilizing the stress-magnetic effect;(4) sensors ultilizing large Barkhausen effect and Matteucci effect;(5)sensors ultilizing the resistance-strain effect and other physical effect etc.
