Influence of Post-Weld Heat Treatment on the Performance of UHSS Joints [PDF]
MaterialsUltra-high strength steel (UHSS) contributes significantly to lightweight design, environmental compatibility and lower fuel consumption. However, it is essential to maintain excellent mechanical properties in terms of structural integrity, strength and ductility after the applied welding process.

Automatic Tool Compensation for an UHSS Automotive Component Using a Compensation Module
Transactions of Materials Processing, 2016 Abstract In the current study, automatic tool compensation is accomplished by using a finite element stamping analysis for a center roof rail made of UHSS in order to satisfy the specifications for shape accuracy. The initial blank shape is calculated from a finite element inverse analysis and potential forming defects such as tearing and wrinkling are
