| Abstract: |
| [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-10Al alloys consist of Al (major phase),AlN(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-10Al alloys is shown as shallow and small dimples.[Conclusion] The YB-10Al alloys exhibit ductile fracture and the fracture mechanism is microporous aggregation type. |
