This could be metal forming, superplastic forming or additive manufacturing processes - all of which would produce the tank parts at close to net shape.
He explains that superplastic forming (SPF) of sheet metal is a niche process that enables the manufacture of lightweight components with complex geometries.
Friction Stir Welding) complement and expand the currently used technologies such as Spin Forming and Superplastic Forming (as well as Superplastic Forming Diffusion Bonding).All the mentioned manufacturing processes will lead to maximumimpact in terms of costs/lead time reduction as well as increasing performances if applied to launchers upper stages structural tanks and their interfaces as well as large satellites and spacecraft tanks.
Superplastic forming technology (SFT), which can dramatically decrease flow/residual stress and improve formation quality, has been commonly used to manufacture complex shapes in sheet or tube.
Finite element simulation of selective superplastic forming of friction stir processed 7075 Al alloy.
Coverage encompasses alloying, deformation and recrystallation, testing, and metallography, as well as practical applications, including superplastic forming. Also covered are emerging powder metallurgy techniques, microstructure and mechanical properties, and corrosion behavior.
It reduces environmental impact through a low cost, high speed laser welding and superplastic forming process for high tensile strength foil (ranging from higher strength carbon steels, stainless and nickel to titanium in thicknesses of 20 to 300 microns) 0.02 - 0.3mm.
The other 66 papers cover processes, process and production planning, presses and press tools, materials and testing, modeling techniques, cutting and joining, microtechnologies, quality and reliability, manufacturing systems, a case study of extending the value-stream-mapping approach to the comprehensive design of a lean sheet metal manufacturing system, analyzing the electric energy consumption in single-point incremental forming processes, and developments in monitoring die condition during superplastic forming.
Among topics of specific papers are manufacturing a titanium spherical and hollow cylinder vessel using blow forming, friction stir processing commercial grade marine alloys to enable superplastic forming, the role of numerical simulation in superplastic forming process analysis and optimization, whether superplasticity is needed for large deformability of wrought magnesium alloys, and analyzing grain-boundary sliding with rotating hexagonal particles.
The characteristics of superplasticity, namely a low flow stress and a large elongation, have led to the development of a variety of 'superplastic forming' (SPF) processes such as forging, extrusion, blow-forming, and so on (Miller and White [1]; Al-Naib and Duncan [2]).
This takes place inside a split-die superplastic forming tool at 900[degrees]C, with the pack being inflated using argon gas.
In addition, new processing techniques such as superplastic forming and advanced powder metallurgy methods are being used on conventional alloys and their derivatives to improve toughness, high temperature properties and fatigue properties.
