Anisotropy influence on flow behaviour and plastic instability of Ti6Al4V sheets deformed in a wide range of temperatures and strain rates
Abstract Ti6Al4V sheets are usually difficult to form at room temperature as a consequence of their reduced number of slip systems. The heating of the alloy below the β-transus temperature is recognized to enhance its formability, reducing the flow...
