摘　　要：采用热压粘合法将一种形状不规则非晶薄带和一种晶体材料复合在一起,制备出双层复合材料。对复合材料中形状不规则的非晶层的晶化进行了X射线衍射研究。然而,由于晶体材料的X射线衍射信号的干扰,很难直接获得非晶层内微观组织结构的衍射信号。本文利用相关分峰知识,推导出分峰计算公式:I=f2(2θ)-af1(2θ),基于此公式研究出了一种新方法,以此方法获得非晶层内微观组织结构的衍射信号,并对非晶层内微观组织结构的转变进行了测量分析。Hot compression was used to bond an irregular amorphous thin ribbon with crystalline material successfully.The crystallization in the irregular amorphous layer was investigated by X-ray diffraction.However,it is difficult to get the microstructure signals of amorphous layer directly because the signals in the bonded crystalline material layer can also be excited.An equation I=f2（2θ）-af1（2θ） for peak separation is derived.Based on the equation,a novel method is performed in this study which can measure the microstructure evolution in amorphous layer.
