摘要
【目的】研究YB-10Al铝合金的物相组成和断口形貌,分析掺杂对合金结构和性能的影响。【方法】利用X射线粉末衍射仪和带能谱的扫描电子显微镜研究两组不同成分的YB-10Al铝合金的物相组成及断口形貌。【结果】YB-10Al铝合金所含物相有Al(主要相)、Al N(少量)、Si(少量)、Fe(微量)等,且两组样品所含物相略有差异;合金断口形貌显示为浅而小的韧窝。【结论】YB-10Al铝合金试样为韧性断裂,断裂机制为微孔聚集型。
【Objective】The phase component and fracture morphology of YB-10 aluminum alloys are studied,and the effects of doping on the structure and properties of the alloy are analyzed.【Methods】The phase component and fracture morphology of two groups of different componential YB-10 Al alloys have been investigated by X-ray powder diffractometer( XRD) and scanning electron microscopy( SEM) with energy spectrum.【Results】The results suggest that the phase of YB-10 Al alloys consist of Al( major phase),Al N( tiny amount),Si( tiny amount),Fe( trace amount) and so forth. There are slight differences of phase component between different samples. The fracture morphology of YB-10 Al alloys is shown as shallow and small dimples.【Conclusion】The YB-10 Al alloys exhibit ductile fracture and the fracture mechanism is microporous aggregation type.
