鋯剛玉莫來石-氮化硼系復合材料的熱疲勞性能

Thermal Fatigue Resistance of Zirconia-corundum-mullite/Boron Nitride System Composites

  • 摘要: 在強制對流的條件下,研究了鋯剛玉莫來石-氮化硼復合材料的熱疲勞行為,給出了亞臨界裂紋擴展的激活能和應力強度因子指數。

     

    Abstract: On condition of forced convection,the thermal fatigue behaviour of zirconiacorundum-mullite/boron nitride system composites are studied.The activation energy for subcritical crack growth and the stress intensity exponent are calculated.
