This paper presents results based on a series of indentation tests (hobbing) performed on supported billets of Coronze, a superplastic alloy of copper, aluminium, silicon and cobalt. The relationship between hobbing force, depth of indentation and strain rate was established. An upper bound techniqu
The stress state during "simple" superplastic bulge forming (without a back pressure) is different from that when a back pressure is applied. In the former procedure, specimens or components are deformed under a biaxial tensile stress state, while in the latter, the deformation is achieved under the
The deformation mechanisms and the thermal stability of AZ31 alloy, processed by various routes, have been investigated. Superplastic deformations could be achieved at flow stresses lower than 10 MPa at 375 β’ C and 10 -4 s -1 in the AZ31 alloy with a grain size of 17 m. The thermal stability of seve
