With the rapid development of low-carbon high strength steel, higher requirements are put forward for matching welding consumables. The deposited metals with 0.62–2.32% Cu addition was prepared by tungsten inert gas via metal cored wire. effect element on microstructure and mechanical properties were investigated. multiphase consists bainite, martensite, residual austenite, martensite-austenite...

We give an excerpt of recent developments in the experimentally benchmarked modeling of bainite formation in the press hardening process. As the press hardening process poses a heavily multi-parameter dependent modeling challenge, we focus on three main branches which complement each other. We emphasise the combination of basic sharp interface and phase field models with pragmatically adapted m...

Professor Ulrich Dilthey’s passion for the science and technology of joining processes is amply reflected in the enormous archive of published work which will forever serve the community. It is a pleasure therefore to be able to present this small story as a tribute to someone who has been a scholar, a gentleman and a leader in this most difficult of subjects. The matter of our everyday world i...

The redistribution of carbon after tempering of a novel nanocrystalline bainitic steel consisting of a mixture of supersaturated ferrite and retained austenite has been analyzed by atom probe tomography. No direct evidence supporting the additional carbon enrichment of austenite beyond that initially achieved during the bainite heat treatment was obtained during subsequent tempering of this hig...
