| 中文摘要 | The surface morphology of in situ deformed, pre-deformed, undeformed and crystallized Zr(47.9)Ti(0.3)Ni(3.1)Cu(39.3)Al(9.4) bulk metallic glass in air at elevated temperatures are investigated to improve the understanding of the effect of plastic deformation on the oxidation. The plastic deformation is performed through instrumental macroindentation, while could provide a well developed shear offset pattern around the indents at lower temperatures. The oxidation experimental results show that the in situ formed and pre-existed shear bands are more susceptible to oxidation. The plastic deformation region during homogenous deformation has also a significant oxidation sensitivity compared with undeformed material. To clarify the oxidation mechanism of shear band, specimens with surface scratches were also studied. The mechanism for the preferential oxidation of shear bands and of the plastic deformation region is discussed. (C) 2011 Elsevier B.V. All rights reserved. |
