The Mechanics of Superplastic Forming - How to Incorporate and Model Superplastic and Superplastic-Like Conditions [PDF]

Materials Science Forum, 2016
Much work has been carried out in understanding the mechanics of superplasticity (SP). Some of the present challenges in SP forming revolve around the use of lower forming temperatures and faster strain rates, which may involve pushing the process boundaries to incorporate “superplastic-like” forming – perhaps also in materials with non-optimized ...

Role of Grain Size and Shape in Superplasticity of Metals

Frontiers in Materials, 2021
Superplasticity is characterized by an elongation to failure of >300% and a measured strain rate sensitivity (SRS), close to 0.5. The superplastic flow is controlled by diffusion processes; it requires the testing temperature of 0.5Tm or greater where

Forming of superplastic ceramics [PDF]

Ceramics International, 1996
Superplasticity in ceramics has now advanced to the stage that technologically viable superplastic deformation processing can be performed. In this article, examples of superplastic forming and diffusion bonding of ceramic components are given. Recent work in biaxial gas-pressure forming of several ceramics is provided. These include yttria-stabilized,

Investigation of the two-stage SPF process of aluminum alloy door frames

Journal of Materials Research and Technology, 2021
The superplastic forming process has been used extensively in aerospace applications for its advantages in manufacture of complicated components. But it has been limited to the long production cycle and the non-uniform thickness distribution of the final

Effect of Yb2O3 on superplastic behavior of laser welded joint of TC4 titanium alloy

International Journal of Lightweight Materials and Manufacture, 2023
The inhomogeneity of joints during superplastic deformation greatly limits the application of laser beam welding/superplastic forming (LBW/SPF). In order to adjust the deformation uniformity of the joint, Yb2O3 with different mass fractions was added to ...
