用扫描电子显微镜研究激光法制备的非晶态金属
Study of non-crystalline metals by laser irradiation using SEM
摘要
用扫描电子显微镜观察分析了铁基(Fe-Ni-P-B-C、Fe-B-C)和铝基(Al-Si、Al-Si-Mg-Mn)共晶试样在高重复频率YAG激光器处理前后的表面形态、金相组织、断口形貌等特征。结果指出经激光处理后的样品表面实现了非晶态转变,该非晶层具有一定的韧性和热稳定性。
Abstract
The surface morphology, crack section morphology and metallographic structure of Fe-and-Al based eutectics (Fe-Ni-P-B-C, Al-Si, Al-Si-Mg-Mn) before and after treatment with high repetition rate YAG laser light were observed with a scanning electron microscope. The results show that the sample surface irradiated by laser light has been changed into Non-crystalline and the non-crystalline layer possesses higher ductility and better thermal stability.
