作者曾对非晶态TbFe_(69)蒸发薄膜的晶化规律进行了研究,发现非晶膜随温度升高经Spinodal分解至400℃左右逐渐进入第一亚稳相阶段,生长出小晶粒.由多晶衍射法测定为α-Fe相,但其晶面间距与稳定相α-Fe有差异.这些亚稳相的单个小晶粒结构究竟如何?这是研究非晶固体中晶体生长过程及其物性所必须考虑的课题.但是由于晶 The author has studied the crystallization rule of the amorphous TbFe_ (69) evaporated film and found that the amorphous film grows out of the first metastable phase with Spinodal decomposition to about 400 ℃ with the increase of temperature. The α-Fe phase is determined by the polycrystalline diffraction method, but its interplanar spacing is different from that of the stable phase α-Fe. What is the single small grain structure of these metastable phases? Its physical properties must be considered. However, due to crystal
