The microstructure and fracture process of an eutectoid pearlitic steel have been observation and analysed by means of electron-diffraction-contrast technique and SEM.
应用电子衍衬技术和扫描电镜等手段,对共析珠光体轨钢的微观结构和断裂过程,进行了观察和分析。

Electrondiffraction results show that these films are amorphous.
电子衍射结果表明薄膜是非晶态的。

The changes of transmission electrondiffraction patterns indicate the phase change has occurred at about 220k, and its crystal parameters change obviously.
