Fabrication and Residual Stresses of Aluminum Nitride Ceramics Sintered at High-pressure

摘要：

High-density AlN ceramics were fabricated without sintering additives at high pressure (5.0 GPa) and temperature (1300-1700 ℃). The sintered bodies were characterized by XRD and micro-Raman spectroscopy (MRS). The values of residual stresses due to the distortion of the AlN lattice were assessed using the Micro-Raman Spectroscopy (MRS). Residual compression stress of the AlN ceramics sintered at 5.0 GPa and 1700 ℃ for 125 min is -2.0 GPa. The residual compression stress increased according to the extension of the sintering time.
