title = "PHASE TRANSFORAMTION DURING ANNEALING OF A COLD-ROLLED DUAL PHASE STEEL GRADE",
abstract = "The transformation behavior of a cold-rolled dual-phase (DP) steel grade during the annealing treatment are investigated in detail. The stages of interest are: recrystallization, dissolution of cementite and formation of austenite during heating and soaking, and the transformation behavior during cooling. For the latter the impact of the cooling rate and an isothermal holding after cooling is studied. Microstructure investigations, dilatometer measurements and the mechanical properties are used to clarify the transformation behavior. During intercritical annealing the austenite fraction is mainly determined by the annealing temperature and to a much lesser extent by the soaking time. A very strong impact on the transformation behavior in cooling results from the microstructure formed during annealing in either the austenite phase field or the austenite-ferrite two-phase field (intercritical annealing). The cooling rate markedly influences the transformation behavior which can be explained by carbon enrichment in the austenite. The best DP structure consisting of a mixture of ferrite and martensite is obtained by cooling with intermediate cooling rates.",
