Suction Casting

TiCu-based bulk metallic glasses with large plasticity (up to 10%) were fabricated by copper mold suction casting. The detailed studies showed that the large plasticity resulted from the nanoscale heterogeneities formed upon solidification, which resulted in extensively shear band formation, branching and interaction.

Mold Casting

Ti-based bulk metallic glasses with minor addition of Ag, Au or Pt elements were prepared by copper mold casting. The Microstructure of the as-cast samples was examined by TEM. Nanoparticles identified as cubic Pd3Ti with crystal planes of (111), (200), (220) and (311) are observed in all the alloys modified by the minor addition of Ag, Au or Pt. The results revealed that the glassy/nanoparticle composited alloys exhibited high strength about 2000 MPa and plastic strain between 1.5-10% due to the inhibition of propagation of shear band.
