Spot welding, particularly resistance spot welding (RSW), is a critical joining process in
automotive industry. The development of advanced high strength steels for applications in …

Novel alloys with high aluminum addition, so-called δ-transformation-induced plasticity
(TRIP), have been developed recently for the third generation of advanced high strength …

The manganese concentration of steels which rely on transformation-induced plasticity is
generally less than 2 wt pct. Recent work has highlighted the potential for strong and ductile …

The reasons behind the limited impact toughness of medium manganese, medium carbon
carbide-free bainitic steels has been discussed in this manuscript. Various hot-rolling …

The unique impact of two types of ferrite, intercritical ferrite and δ-ferrite on austenite stability
and deformation behavior of hot-rolled Fe–11Mn–4Al–0.2 C transformation-induced …

Improving strength may lightweight car bodies by thinning the structure gauge while bearing
the same crash loads. Development of the third generation advanced high-strength steels …

In this research a novel concept, quenching and tempering-associated partitioning (Q–T &
P), has been proposed by a new alloy design with a 3.5 wt.% aluminium addition, in which …

In the present study four different density reduced TRIP steel concepts with varying Mn and
Al contents were investigated with regard to their microstructure, mechanical properties and …
