| 英文摘要 | The stress-induced alpha '' martensite transformation always sacrifices the yield strength in titanium alloys with specific beta stability. Here, a detailed analysis for the microstructure transformation of the stress-induced alpha '' martensite during isothermal aging is carried out using the traditional experimental characterizations based on the transmission electron microscope (TEM) in an alpha + beta Ti-alloy, namely Ti-3Al-5Mo-4.5 V (wt%) alloy. The results show that the stress-induced alpha '' plates transform to the isothermal-alpha '' due to the local solute redistribution (Al, Mo, V) during the one-step isothermal aging at 400 degrees C. Subsequently, the ladder-like alpha(s) precipitates due to the decomposition of stress-induced alpha '' or isothermal-alpha '' after aging at 550 degrees C, eliminating the influence of stress-induced alpha '' martensite on the yield strength. Besides, the ultrafine alpha(s) is obtained by the refinement of isothermal omega during two-step aging at 550 degrees C. And the ultimate tensile strength increases slightly due to the precipitate of ladder-like and ultrafine alpha(s) after two-step aging at 550 degrees C. The present study provides a novel way to obtain the alpha lamellae and improve the mechanical properties of titanium alloys. |
