The shock compression properties for permanent magnet Nd2Fe14B were studied in the shock pressure range of 19~78 GPa, using a two-stage light-gas gun. The Hugoniot data of Nd2Fe14B with initial average density 7.346 g/cm3 were measured by the impedance matching method. The experiment results indicate a good linearity between the shock wave velocity and the particle velocity i.e. C0, λ are obtained as 3.686 km/s, 1.059. Shock compression curve in the Nd2Fe14B shows a stable compression course and there is no evidence phase transition in present pressure range. The small λ displays that the Nd2Fe14B material leans to loosen state and is prone to compression. At the same time, it also provides corresponding experiment parameters for calculation of EOS and application of pulse power resource.

利用二级轻气炮对恒磁体钕铁硼进行冲击压缩,采用阻抗匹配法进行测量,获得了平均初始密度为7.346 g/cm3的钕铁硼Hugoniot关系数据。实验结果表明,该种钕铁硼在19~78 GPa范围内,其D-up满足线性变化关系,即:C0、λ分别为3.686 km/s、1.059,是一种稳定的压缩过程,其间没有相变产生。而较小的λ值表明该种钕铁硼材料偏向于疏松体结构,且容易被压缩。同时实验结果也为其状态方程和脉冲功率源等方面的研究工作提供了可资参考的实验参数。

利用二级轻气炮对恒磁体钕铁硼进行冲击压缩,采用阻抗匹配法进行测量,获得了平均初始密度为7.346 g/cm3的钕铁硼Hugoniot关系数据。实验结果表明,该种钕铁硼在19~78 GPa范围内,其D-up满足线性变化关系,即:C0、λ分别为3.686 km/s、1.059,是一种稳定的压缩过程,其间没有相变产生。而较小的λ值表明该种钕铁硼材料偏向于疏松体结构,且容易被压缩。同时实验结果也为其状态方程和脉冲功率源等方面的研究工作提供了可资参考的实验参数。

钕铁硼  /  Hugoniot  /  冲击压缩

The shock compression properties for permanent magnet Nd2Fe14B were studied in the shock pressure range of 19~78 GPa, using a two-stage light-gas gun. The Hugoniot data of Nd2Fe14B with initial average density 7.346 g/cm3 were measured by the impedance matching method. The experiment results indicate a good linearity between the shock wave velocity and the particle velocity i.e. C0, λ are obtained as 3.686 km/s, 1.059. Shock compression curve in the Nd2Fe14B shows a stable compression course and there is no evidence phase transition in present pressure range. The small λ displays that the Nd2Fe14B material leans to loosen state and is prone to compression. At the same time, it also provides corresponding experiment parameters for calculation of EOS and application of pulse power resource.
