 Abstract
 PDF
- This work is to present a new synthesis of metallic glass (MG)/metallic glass (MG) composites using gas atomization and spark plasma sintering (SPS) processes. The MG powders of Cu_54Ni_6Zr_22Ti_18 (CuA) and Ni_59Zr_15Ti_13Nb_7Si_3Sn_2Al_1(NiA) as atomized consist of fully amorphous phases and present a different thermal behavior; T_g (glass transition temperature) and T_x (crystallization temperature) are 716K and 765K for the Cu base powder, but 836K and 890K for the Ni base ones, respectively. SPS process was used to consolidate the mixture of each amorphous powder, being CuA/10%NiA;and;NiA/10%CuA in weight. The resultant phases were Cu crystalline dispersed NiA matrix composites as well as NiA phase dispersed CuA matrix composites, depending on the SPS temperatures. Effect of the second phases embedded in the MG matrix was discussed on the micro-structure and mechanical properties.
