Important results from the project
The prestudy results demonstrated that it is possible with a flexible one-alloy concept with different thermomechanical processing yield sufficient properties, such as tensile strengths 600-1600MPa, and good enough elongation values needed for formability. The one-alloy concept did therefore fulfil the existing properties identified for the reference alloys, including soft and formable ferritic steel, and fully hard press hardening steel.
Expected long term effects
Long term effects from the prestudy work, and to be studied in planned upcoming full scale project, is to evaluate performance for the one-alloy concept by including other performance metrics like cold/hot formability, weldability, coatabilty, etc. This testing is now made on industrial material with demonstrator testing. Effects of implementation is also included in full scale project, with interest about circularity, resilience and material handling, design effects, etc.
Approach and implementation
The initial part of the project included a literature review and definition of reference cases, with their properties and performance metrics that should be fulfilled. A roadmap (system design chart) was constructed, which now acts as a plan for full scale validation. Material testing was made small scale, thermomechanically simulated, structures characterised and validated, and properties evaluated.
