Using gas-atomized Ti-based metallic glassy powder, or the mixed powder blended with hydroxyapatite (HA) powder, we produced Ti-based bulk metallic glasses (BMGs) and the composites with high strength and satisfying large size requirements by a spark plasma sintering (SPS) process. The Ti-based BMGs and the composites with excellent properties and without toxic elements make it possible to apply as biomedical materials.

Consolidation Behavior

We investigated consolidation behavior of gas-atomized Cu50Zr45Al5 metallic glassy alloy powders by a spark plasma sintering (SPS) process. Density of the sintered samples increased with an increase in sintering temperature. The nearly full density samples without crystallization could be attained by the SPS process at sintering temperature of 693 K under pressure of 600 MPa. The produced samples exhibited high-strength and met large-size requirement. The SPS process makes it possible to fabricate the large-size bulk metallic glasses without limitation of dimensions and alloy system.

Composite Samples

Large-size Ni-based bulk metallic glass (BMG) composite samples exhibiting simultaneously high strength, enhanced plasticity and improved conductivity were produced by spark plasma sintering of mixed glassy powder blended with high-conductive Cu particulates. This opens new possibilities for the applications of the BMG composites as functional and structural materials.

Using the mixed powders containing gas-atomized powders of metallic glassy alloys (Cu50Zr45Al5, Fe73Si7B17Nb3, Ni52.5Nb10Zr15Ti15Pt7.5) blended with high-conductive Cu particulates, we produced bulk metallic glassy alloy composites with high strength and high electrical conductivity, as well as with enhanced plasticity and satisfying large size requirements by a spark plasma sintering process. In this paper we present and review our research results on the fabrication and properties of the bulk glassy alloy composites by the spark plasma sintering process.
