Abstract In situ microcantilever bending tests were performed on martensite islands in a dual-phase (DP) steel to extract the fracture toughness of at microscale and understand damage initiation during forming DP steels. All microcantilevers produced through FIB milling. The do not exhibit linear elastic brittle fracture; instead, significant ductile tearing is observed. conditional extracted b...

Abstract Modern car bodies are constantly relying higher proportions of high and ultra-high strength steels. In the past, increase in material strengths led to a conflict regarding complexity component geometries. Limits formability reached compromises had be made part design. By integrating application-oriented problems into development, these limits expanded with respect given requirements. W...
