| Abstract: | Prepared CNTs reinforced TiAl alloy composite by laser casting. The sample was characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). The results showed that the main phase of the ingot is TiAl and Ti3Al alloy. A spot of CNTs remained on the fracture surface indicated it is ductile fracture. Besides, the microhardness was improved remarkably in comparison to TiAl matrix. Expecially, the microhardness was increased to 738 HV from 647 HV of TiAl matrix when w(CNTs) is 1.5%. |
