Mechanical clinching of ultra-high strength steel sheets and strength of joints

Journal of Materials Processing Technology, 2014
Abstract Ultra-high strength steel sheets having low ductility were joined by mechanical clinching with dies for control of metal flow. The diameter and depth of the die were modified to relieve concentration of deformation of the sheets for avoidance of the occurrence of sheet fracture.

Incremental Bending of Ultra-High-Strength Steels

Key Engineering Materials, 2011
Utilisation of ultra-high-strength steels (UHS) has increased, particularly in the automotive industry. By using these materials vehicle structures can be lightened. However, one of the problems of UHS is weak formability. Materials fracture easily with small bending radii and the minimum bending radii are rather large.

Welding of Ultra High Strength Steels

Advanced Materials Research, 2013
The ongoing need to reduce the weight of products while increasing strength has resulted in new generation steel manufacturing using special heat treatments to produce High Strength Steels (HSS) and Ultra High Strength Steels (UHSS) with up to 1700 MPa tensile strength.

Alloyed Ultra‐High Strength Steels

Laser Technik Journal, 2016
AbstractNew ultra‐high strength steels provide new lightweight opportunities and improve crash properties in future car bodies. Understanding the joining process as well as the response of the base materials on heat input is in order to create designs exploiting the full potential and fulfill the extensive requirements.

FEM - Modeling of Bendability of Ultra-High Strength Steel

Key Engineering Materials, 2013
Ultra-high strength steels have been widely used in different industrial applications. It is necessary to understand the behavior of these materials in common forming processes such as air bending. It is known that the bendability of ultra-high strength steels is lower than other high-strength steels but what are yet to be discovered are the parameters

Springback analysis of ultra high strength steel

AIP Conference Proceedings, 2013
It is an inevitable trend in the automotive industry to apply more and more high strength steels and even ultra-high strength steels. Even though these materials are more difficult to process the development time of forming tools must be reduced. In order to keep the development time under control, simulation tools are used to verify the forming ...
