Abstract
Splitting behavior of tensile specimens of low carbon 2% Mn steel and 2% Mn-Nb-V steel that had been cold rolled and aging treated were studied. The occurrence of splitting depends on steel composition, degree of cold reduction and aging treatment conditions. The susceptibility to splitting is closely related to the weakness of ferrite grain boundaries This weakness is attributed to elongation of the ferrite grains in the direction of cold rolling and also to precipitation and growth of carbides at the grain boundaries during the aging treatment.
