Microstructure characterization of high‐pressure induced texture in fully densified zirconium diboride ceramics

Abstract

AbstractFully dense oriented monolithic zirconium diboride (ZrB2) ceramics with <0001> fiber texture were fabricated using high‐pressure spark plasma sintering. The <0001> fiber texture is proposed to be triggered by grain rotation, as (0001) <> basal slip of ZrB2 was activated during sintering. The high temperature, uniaxial high pressure, and uniform starting particles play a vital role in the texture formation of ZrB2 ceramics. The result provides visible evidence for the occurrence of plastic deformation during high‐pressure‐assisted sintering.
