چکیده انگلیسی
The transient flow behaviour in Timetal 834 titanium alloy was studied in the temperature range between 400 °C and 475 °C by means of stress relaxation and reloading during tensile testing at a strain rate of 6.67 × 10−4 s−1. The increment in flow stress during reloading (Δσf) and the decrement in flow stress during stress relaxation (Δσr) were measured at different strains at each temperature. The observation of maximum value of Δσf and Δσr, normalized with respect to the Young's modulus at the corresponding temperature, confirmed that the maximum dynamic strain aging (DSA) effect in this alloy occurs at 450 °C.
