    摘要:

    研究TA15合金在3.5%NaCl鹽霧環(huán)境和不同應(yīng)力比 (R= –1、0.06，0.5) 條件下的腐蝕疲勞性能，并建立合金腐蝕疲勞的Sa-Sm-N曲面方程：N=1.83×1013/[888Sa /(888–Sm)–329.51]3.65。根據(jù)疲勞過程中試樣循環(huán)位移響應(yīng)得出，TA15合金的循環(huán)硬化/軟化行為與施加應(yīng)力比有關(guān)。對(duì)腐蝕疲勞斷口的SEM觀察進(jìn)一步表明，合金在鹽霧環(huán)境下的裂紋萌生呈現(xiàn)多源特征，且裂紋源區(qū)大多呈解理形貌，裂紋擴(kuò)展區(qū)材料抗力變化與應(yīng)力比相聯(lián)系。

    Abstract:

    In this paper, the corrosion fatigue properties of TA15 alloy in 3.5%NaCl salt spray were investigated at different stress ratio(R= –1, 0.06 and 0.5). An equation describing the Sa-Sm-N curved surface of the alloy was established on the basis of the experimental results, that is, N=1.83×1013/[888Sa /(888–Sm)–329.51]3.65. The result according to the cyclic displacement response of the fatigued alloy show that the cyclic hardening/softening characteristic of TA15 alloy in the salt is was dependent on the applied stress ratio R. SEM observations of the fracture surface indicate that the corrosion fatigue fracture of TA15 alloy presents multi-fatigue crack initiations characterized mainly by the cleavage morphology. In the crack growth zone, the fracture morphology shows that the change of deformation resistance is relative to the stress ratio.
