Performance Of Cyclic Annealing At Steel Formability Improvement

The performance of cyclic annealing at steel formability improvement has been investigated. The investigations were done on steel Ck 60 (DIN). The steel formability was investigated on the basis of the true strength-strain curve which is fundamental property that determines the steel formability. Stress-strain curves are determined by compression test.Steel with good formability has small strenght properties and high plasticity and toughness. Good formability can be obtained by the isothermal or cyclic annealing. On the basis of actual research it was found that better formability properties are obtained by the appropriate cyclic heat treatment then by isothermal annealing.The change of steel formability by cyclic annealing directly depends on the structure fineness and thermal hardening
