Effect of prestrain and aging treatment on microstructures and tensile properties of Ti–10Mo–8V–1Fe–3.5Al alloy
چکیده انگلیسی

Higher strength and lower ductility have been observed in the prestrained and aged Ti–10Mo–8V–1Fe–3.5Al (TB3) alloy. In order to improve the ductility of prestrained TB3, two-step aging treatment was introduced. Tensile tests showed that the elongation of prestrained samples was increased to the same level of the unstrained and peak-aged ones without decrease in strength by the two-step aging. Transmission electron microscopic (TEM) examinations revealed that dislocations introduced by prestrain were almost eliminated by the two-step aging treatment, which was proposed to be the main cause for the ductility recovery. In addition, in the prestrained and aged TB3 samples, parallel α plates of one variant were generally observed under TEM.
