| Abstract Scope |
The sizes of metallic glasses (BMGs) are limited due to their requirement of cooling rate during the solidification process. In the supercooled liquid region (SLR), BMGs usually exhibit superplasticity and high forming ability. In the present work, the rheological behavior and oxidation of BMGs Zr61Cu25Al12Ti2 (ZT1), Cu44.25Ag14.75Zr36Ti5 (CT1) and Ti32.8Zr30.2Cu9Ni5.3Be22.7 (ZT3) were investigated in the SLR. The rheological behavior of were investigated on Gleeble3500 in their SLR. The results indicate that BMG ZT1 takes place Newtonian flow with the selected temperature deformation rate, while BMGs CT1 and ZT3 show thermoplastic processing ability with no ideal Newtonian flow. The thickness of surface oxide for ZT1 is less than CT1 and ZT3 due to the elemental addition of Ag and Be, respectively. The plastic bonding of ZT1 was tested on Gleeble3500 in its SLR and the effective bonding was obtained which are promising for the fabrication of large size BMGs. |
