Constitutive model and microstructural evolution of hot deformation of investment-cast Ti-4Al-0.005B alloy

Hot compression tests of investment-cast Ti-4Al-0.005B (TA5) alloy were conducted over a wide temperature range of 750 °C–850 °C at strain rates of 0.01–1 s ^−1 . Based on the flow stress curve and dynamic material model, a constitutive equation is established. The thermal deformation behavior and m...
