Applied Pressure on Altering the Nano-Crystallization Behavior of Al₈₆Ni₆Y_4.5Co₂La_1.5 Metallic Glass Powder during Spark Plasma Sintering and Its Effect on Powder Consolidation

Figure 3

SEM mapping results of Al and Ni as well as O in a selected area of an SPS-processed sample sintered at 248.5°C for 2 min under 200 MPa. The distribution of Y, Co, and La is generally homogeneous and similar to that of Ni.
