A New Approach for Determining the Optimum Pressure–Time Diagram in Superplastic Forming Process [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2013
Superplastic materials show huge amount of deformation in low strain rates and temperature above half of melting point. In superplastic forming, estimating the pressure–time diagram and thickness distribution has significant importance.

Vacuum moulding of a superplastic in two dimensions

, 1999
A mathematical model is proposed for the process of vacuum superplastic forming. The model exploits the fact that in most industrial applications the sheet aspect ratio (thickness/sheet width) is small.

Superplastic Deformation and Superplastic Forming.

Journal of the Japan Society of Powder and Powder Metallurgy, 1991
The paper were reviewed recent researches of parameters which control the flow and ductility of micrograin superplastic materials. Particular attention was emphasized to the strain rate sensitivity of the flow stress, m and high rate superplasticity. It has been pointed out that the origin of these characteristics is the grain boundary sliding process,
