摘要：
On the basis of microstructural observations in titanium and its alloys, a limit on the workability parameters has been proposed in the literature for flow localization or fracture to occur during hot deformation of materials. In this letter, the fixed limit on the workability parameters is verified by considering the flow stress data and the microstructural observations of IN718.
