Abstract

In this study, the high-temperature ductility behaviour of an Al-Si-coated 22MnB5 sheet was investigated. The mechanical properties of Al-Si-coated 22MnB5 boron steel were examined via hot tensile tests performed at temperatures ranging from 400 to 900 degrees C at a strain rate of 0.083 s(-1). The deformation and fracture mechanisms under hot tensile testing were considered in relation to the testing data and to the fracture-surface observations performed via SEM. The hot ductility of the tested boron steel was observed as a function of increasing temperature and the Al-Si-coated 22MnB5 boron steel exhibited a ductility loss at 700 degrees C.
