【Abstract】 The heating procedure and forming process of 1 000 mm die forged TC4 titanium alloy steam turbine blade were studied. Macro and micro structures, mechanical properties and corrosion fatigue properties in all three main parts of the blade were comparatively analysed. The processability and properties of the blade were comprehensively evaluated.更多还原
