| 中文摘要 | 利用搅拌摩擦加工技术制备了一种新型的非晶增强铝基复合材料,用金相、显微硬度计及扫描电镜等分析复合材料的显微组织、硬度以及成分组成.结果表明,复合材料主要由母材和非晶带经搅拌摩擦加工后交替形成的层状结构组成,其显微硬度与母材相比有所提高.复合材料主要由-αAl,Mg2Al3,MnAl6以及La3Al11等物相组成,原始非晶带经搅拌摩擦加工后存在一定的晶化特征,而非晶的晶化可能是摩擦热、机械搅拌力以及轴肩压力等综合因素共同作用的结果.; A novel aluminium metal matrix composite reinforced with Al-based amorphous was fabricated by friction stir processing.The microstructure,microhardness and chemical composition of the composite were analyzed by metallography,microsclermeter and scanning electron microscope.The test results indicate that the composite is composed of an obvious sandwich structure including amorphous strip and base material.The hardness of the composite is higher than that of base metal.The phase constituents of the composite are composed of α-Al,Mg2Al3, MnAl6 and La3Al11.An obvious crystallization characteristic occurs in the original amorphous strip of the composite,in which the crystallization process may be effected by thermal friction,mechanical stirring and pressure forces.; 国家自然科学基金(50875146); 中国博士后科学基金资助项目(20080430377) |
