The SEM micrographs of fractured surface of samples prepared by various SPS conditions: (a) 573 K/50 MPa, (b) 623 K/50 MPa, (c) 673 K/50 MPa, (d) 573 K/100 MPa, (e) 623 K/100 MPa and (f) 673 K/100 MPa. The images show the difference in the microstructures and display the formation of platelet-like features.
