Abstract

To boost the fatigue resistance characteristics of TC11 titanium alloy under thermo-mechanical coupling, the effects of plasma zirconizing (Zr), ultrasonic surface rolling process (USRP), and the plasma zirconizing followed by USRP treatment (Zr + USRP) on the high-temperature fatigue behavior of TC11 titanium alloy were investigated. The findings indicate that the plasma zirconizing induced microstructural weakening and stress concentration in surface regions, reducing the fatigue resistance at 500 ℃. The USRP treatment increased the fatigue limit of TC11 alloy samples by 5.5 % at 500 °C. And this enhancement was attributed to the surface layer microstructural refinement, surface roughness reduction, the introduction of compressive residual stress (CRS) field characterized by a deep distribution and high magnitude, which suppressed the initiation and propagation of fatigue cracks at high temperature. The high-temperature fatigue limit of the TC11 alloy was further increased by 7.3 % with the combined Zr + USRP treatment. Plasma zirconisation produced a solid solution strengthening effect pinning the dislocations formed treated by the USRP, improving the CRS field stability and microstructural stability of the TC11 alloy treated using USRP in the thermo-mechanical coupling environment. As a result, the initiation and propagation of fatigue cracks in TC11 alloy had been effectively prevented under high-temperature conditions.

采用等离子体锆化和超声表面轧制相结合的方法提高TC11钛合金的耐高温疲劳性能

为了提高TC11钛合金在热-机械耦合下的抗疲劳性能，研究了等离子体锆化（Zr）、超声表面轧制（USRP）和等离子体锆化后USRP处理（Zr + USRP）对TC11钛合金高温疲劳性能的影响。结果表明：等离子体锆化导致合金表面组织弱化和应力集中，降低了合金在500℃下的抗疲劳性能；500℃时，USRP处理使TC11合金试样的疲劳极限提高了5.5%。这种增强是由于表层组织细化，表面粗糙度降低，引入了分布深、强度大的残余压应力场，抑制了高温下疲劳裂纹的萌生和扩展。Zr + USRP复合处理使TC11合金的高温疲劳极限进一步提高了7.3%。等离子体锆化对USRP处理后形成的位错产生固溶强化作用，提高了USRP处理后TC11合金在热-机械耦合环境下的CRS场稳定性和显微组织稳定性。在高温条件下，有效地防止了TC11合金疲劳裂纹的萌生和扩展。
