Abstract

Abstract

The influence of alloy composition and microstructure on the yield-point elongation of continuous annealing cold-rolled dual phase sheet steel has been investigated. The experimental results denoted that the yidld-point elongation of cold-rolled dual phase sheet steel decreases with increasing the manganese equivalence and the Martensite volume fraction in alloy. In order to prevent the yield-point elongation occurring the manganese equivalence in alloy must exceeds 1.61%, and the threshold value of Martensite volume fraction is 7%.
