Hot compressive deformation tests of as-cast burn resistant titanium alloy (Ti-35V-15Cr-Si-C) were performed on the Gleeble-1500 simulator in the temperature range of 900~1200 °C, over the range of strain rate from 10-3 s-1 to 1 s-1. The compressive true stress vs. true strain curves were measured. The discontinuous yielding phenomenon was explained. The hot processing maps developed on the basis of dynamic material model (DMM) exhibits the following three domains. The alloy dynamic recovery and continuous recrystallization in the temperature range from 900 °C to 1030 °C and at lower strain rate (＜0.1 s-1). A peak power dissipation efficiency area of 50%~65% occurring at higher temperature (≥1030 °C) and lower strain rate. In addition to dynamic recovery and continuous recrystallization, the carbide solution phenomenon is observed. The alloy exhibits a wide region of flow instability manifested by flow localization and carbide solution at higher strain rate. The ‘Necklace’ dynamic recrystallization occurs at the strain rate of 1 s-1
