摘要
The tensile properties before and after exposed at 600 °C for 100 h and creep strain at the condition of 600 °C/150 MPa/100 h were measured for Ti-1100 and Ti-1100 with 0.1%(mass fraction) yttrium, respectively. The microstructures of unexposed and thermally exposed specimens were studied by optical microscopy and transmission electron microscopy. The addition of 0.1% Y to Ti-1100 is beneficial to the improvement of tensile ductility, thermal stability and creep property of the alloy, which is related to the microstructural changes, precipitated phases (α2 phase and silicide) and dislocation structures resulted from the presence of Y2O3 oxide.
