摘要
Fe_(20)Al_(80)晶态粉末经180小时的机械球磨后,X射线衍射、透射电子衍射和差热分析实验表明,其已由原来的晶态粉末变成了非晶态粉末。
Fe_(20)Al_(80) crystalline powder was ball milled for 180 hours. X-ray diffraction, transmission electron diffraction and differential thermal analysis experiments show that powder sample transformed from crystalline into amorphous after ball milling.
