| Abstract |
Interrupted cooling in the run-out table after hot rolling is a processing strategy to
produce dual phase ferrite-martensite steel strips. The effects of interrupted cooling temperature
and time after austenitizing at 1150 °C are investigated. This is done to establish the conditions for
austenite to transform into ferrite-martensite microstructures in a Mn-Cr-Mo strip produced from a
CSP (Continuous Strip Processing)-type thin slab. The results show that dual phase microstructures
can only be obtained when interrupted cooling is performed at 725
