Endoh等人曾用非弹性中子散射实验方法系统地研究了铁基晶态因互合金的声子色散曲线与温度的关系,结果表明,低频声学模式在磁相变温度以下变软.这种与温度有关的声子软化现象与用超声波法测得的弹性软化是一致的.已知某些铁基非晶态合金也显示出因互效应.这些具有长程无序结构非晶态因瓦合金是否会表现出类似的声子软化现象显然是
Endoh et al. Have systematically studied the relationship between the phonon dispersion curve and the temperature for the Fe-based intermetallics by using the inelastic neutron scattering experiment. The results show that the low-frequency acoustic modes soften below the magnetic transformation temperature The temperature-dependent phonon softening is consistent with the elastic softening measured by the ultrasonic method.It is also known that some iron-based amorphous alloys also show intermolecular effects due to the mutual effect, Whether it will show a similar phonon softening apparently is
