The effect of a tramp element Cu on the hot workability of stee]s was investigated in this paper. The number of surface cracks occurring in the specimenswhich were tensi]e-deformed after oxidized was measured to assess the effect of small amounts of Cu (0.30/0)

Anapproach to predict mechanical properties of hot-rolled multi-phase steels referring to the stress-strain curves is proposed. Different
