高温FeNiCo磁致伸缩合金及制备方法
摘要：
本发明公开了一种高温FeNiCo磁致伸缩合金及制备方法，该合金化学成分的重量百分比为：Ni:30.0～55.0%、Co:1.0～22.0%、Cr:1.0～3.5%、Mo:1.0～3.5%、Ti:1.0～3.0%、Al:0～2.0%、B：0～0.006%，余量为Fe。本发明的高温磁致伸缩合金，具有高的居里温度，在较宽的温度范围内，具有良好的磁性能和大的饱和磁致伸缩系数能够满足高精度仪器仪表的高温使用要求。
摘要（英）：

The invention discloses a high temperature FeNiCo magnetostriction alloy as well as a preparation method thereof. The alloy comprises the following chemical components in percent by weight: 30.0-55.0% of Ni, 1.0-22.0% of Co, 1.0-3.5% of Cr, 1.0-3.5% of Mo, 1.0-3.0% of Ti, 0-2.0% of Al, 0-0.006% of B and the balance of Fe. The high temperature magnetostriction alloy disclosed by the invention has high Curie temperature, good magnetic performance and great saturated magnetostriction coefficient in a relatively wide temperature range, and can satisfy the using demands of high precision instruments and meters at high temperatures.
