Abstract

In order to comprehensively evaluate the influence of alloy structure on the competition mechanism of slip-cleavage failures during ultra-high cycle fatigue process of Ti-alloy, a competition failure model considering the maximum stress (σ_max) was constructed, and then the competition mechanism among failure modes was quantitatively described. Furthermore, the influence of microstructure (surface defects, $α$ -grain size and α-grain content) on the competition mechanism was revealed in detail by means of the control variable method. Meanwhile, ultra-high cycle fatigue tests of TC4 Ti-alloy under stress ratios of -1, -0.3 and 0.1 were carried out at room temperature. The S-N curves obtained under three stress ratios were bilinear, and TC4 Ti-alloy showed three failure modes, namely surface slip failure, surface cleavage failure and internal cleavage failure. The GP extreme value distribution function is used to clarify the distribution characteristics of the surface defect size, and the predicted extreme size of the surface defect is 5.69 μm, which is defined as the thickness of the sample surface area. Next, the coupling effect of microstructure variables such as control volume, external load, α-grain content and α-grain size, the increase or decrease of σ_max value is taken as the main factor of fatigue failure mode transformation of TC4 Ti-alloy and the competitive failure model is constructed. The calculation results show that the model prediction results have a good correlation with the experimental data. Finally, the effect of W value, α-grain size and α-grain content on the slip-cleavage competition failure mechanism of TC4 Ti-alloy was investigated by the control variable method. It is concluded that smaller W value, larger α-grain size and less α-grain content are beneficial to the internal cleavage failure of TC4 Ti-alloy. The value of W does not affect the probability of surface slip failure, and the increase of α-grain size or the decrease of α-grain contentis beneficial to the surface slip failure of TC4 Ti-alloy; The smaller W value, larger α-grain size and less α-grain content is all conducive to internal cleavage failure of TC4 titanium alloy.

Key words: metallic materials very-high cycle fatigue failure mechanism TC4 titanium alloy slip-cleavage competition failure
