【摘要】：通过X射线衍射仪和场发射扫描电镜等实验设备,对比分析了喷射沉积法和铜模吸铸法制备的La_(62)Al_(16)(Cu,Ni)_(22)非晶合金的晶化过程和在不同退火温度下的晶化组织。结果表明沉积态La_(62)Al_(16)(Cu,Ni)_(22)非晶合金晶化主要析出纳米级的Al、Al Ni、La和未知相,析出相呈均匀分布,组织结构较好,而吸铸态La_(62)Al_(16)(Cu,Ni)_(22)非晶合金晶化后析出La和La(Cu,Ni)相,析出相颗粒尺寸大小不一,且分布不均匀,从而证明喷射沉积法作为La_(62)Al_(16)(Cu,Ni)_(22)块体非晶合金的制备方法,具有一定的优势。
[Abstract]:By means of X-ray diffractometer and field emission scanning electron microscope, The Crystallization process and the Crystallization Microstructures of the amorphous Alloys prepared by spray deposition method and Copper Die suction casting method were compared and analyzed. The results show that the crystallization of the amorphous alloys is mainly characterized by the precipitation of nanocrystalline Aldol Nigni La and unknown phases, and the results show that the amorphous alloys are characterized by the crystallization process and the crystallization structure at different annealing temperatures. The results show that the crystallization of the amorphous alloys is mainly characterized by the precipitation of nanocrystalline Aldol nion La and unknown phases. The precipitated phase is uniformly distributed, and the microstructure is better, while La and La-Cu-Ni) are precipitated after crystallization. The size of the precipitated phase is different, and the distribution of the precipitated phase is not uniform. It is proved that the spray deposition method has some advantages as the preparation method of La-Shang 62AlN / AlP16 / CuSN / Nix / NII / 22) bulk amorphous alloy. The results show that the method of spray deposition has a certain advantage in the preparation of the bulk amorphous alloy.
