Oxidation can drastically change mechanical properties of nanostructures that typically have
large surface-to-volume ratios. However, the underlying mechanisms describing the effect …

General Motors has developed Quick Plastic Forming (QPF) as a hot blow forming process
capable of producing aluminum closure panels at high volumes. This technology has been …

The mechanical behaviours of magnesium alloy (WE43) at cryogenic temperatures are
investigated. The significant improvement in both fracture strength (28%) and strain-to …

A two-step method of forming a part and a method of designing a preform shape are being
discussed. The part may be formed from lightweight material to an extent that would …

The use of lubricant for hot stamping process of sheet material can reduce the tendency of
adhesion between work-piece and tool significantly and the friction coefficient. However, the …

Aluminium alloys are commonly used as lightweight materials in the automotive industry.
This non-ferrous family of metallic alloys offers a high versatility of properties and designs …

Superplastic forming has already been proven as a practical solution for manufacturing
lightweight components in niche applications such as the aerospace and luxury cars …

Despite considerable advantages with regard to formability and tooling costs, superplastic
forming (SPF) has been mostly limited to low-volume production due to relatively long cycle …

The conventional superplastic forming (SPF) of complex and deep geometries can result in
excessive thinning and necking. To address these issues, a two-stage SPF process has …

Deformation microstructures generated during the high temperature sliding of a wrought Mg–
3% Al–1% Zn alloy (AZ31) were investigated to delineate the micromechanisms of wear and …
