• Estimation of residual stress relaxation in low alloy steel with different hardness during fatigue by in situ X-ray measurement

  Hayama: M., Kikuchi S., Tsukahara M., Misaka Y., Komotori J.

  International Journal of Fatigue （International Journal of Fatigue)  178 2024.01

  ISSN  01421123

  　View Summary

  In situ X-ray stress measurements were conducted to investigate the relaxation of compressive residual stress induced by fine particle peening during fatigue. To quantitatively assess the stability of the compressive residual stress, a concept of relaxation threshold stress was proposed. The relaxation threshold stress, which indicates the stability of the compressive residual stress, showed a direct correlation with specimen hardness. If the combined value of the compressive residual stress and compressive applied stress surpass the relaxation threshold stress, then the compressive residual stress relaxes. The relaxation threshold stress can be used to estimate the relaxation that occurs during fatigue.

• Effect of surface characteristics on the axial fatigue properties and wear resistance of Ti-6Al-4V alloy nitrided by gas blow induction-heating

  S. Takesue, R. Suyama, M. Hayama, Y. Koyanagi, Y. Misaka, J. Komotori

  Engineering Failure Analysis （Engineering Failure Analysis)  157 （ 107933 ）  2024

  Accepted,  ISSN  13506307

  　View Summary

  The effects of surface characteristics on the axial fatigue properties and wear resistance of the GBIH-nitrided titanium alloy were investigated to improve the fatigue strength and wear resistance of Ti-6Al-4V alloy rapidly nitrided by induction-heating in a nitrogen atmosphere with blowing nitrogen gas (GBIH-nitriding). The fatigue strength of the GBIH-nitrided Ti-6Al-4V alloy was lower than that of the mirror-polished specimen owing to the formation of a brittle nitrogen compound layer and grain coarsening. Fatigue tests using specimens prepared by combining GBIH-nitriding and particle collision treatments revealed that the formation of nitrogen diffusion layers at the outermost surface and the generation of compressive residual stress without forming surface asperities increased the fatigue strength of the GBIH-nitrided Ti-6Al-4V alloy. Moreover, the formation of a nitrided layer and suppression of surface asperities effectively improved the wear resistance of the Ti-6Al-4V alloy. Therefore, formation of a nitrogen diffusion layer and the introduction of compressive residual stress without grain coarsening, a compound layer, and surface asperities increased the fatigue strength and wear resistance of the GBIH-nitrided alloy.
