| Abstract: | The alloy rods with diameters of 3.0 mm of Zr63Cu17.5Ni10Al7.5TM2(TM=Y,Fe,Ti) were prepared by copper mold with suction casting method in water cooling crucible.The analysis by XRD,DSC,mechanical properties testing and fracture scanning(SEM).The analysis showed that Y,Fe,Ti-doped alloys can be completely amorphous,Fe,Ti elements doped samples have a high glass-forming ability and thermal stability(ΔTx>86 K,Trg>0.87),The elements doped amorphous Fe samples behave high mechanical properties,the breaking strength up to 2338 MPa. |
| Keywords: | Zr-based bulk metallic glass stress glass-forming ability mechanical properties |
