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.eninfo:eu-repo/semantics/closedAccessHot ductilityMechanical propertiesAl-Si-coated 22MnB5Dynamic recrystallisationFractographyTensile deformation behaviorsConstitutive modelScience & technology - other topicsMaterials scienceMetallurgy & metallurgical engineeringAluminum coatingsBoronDuctilityFractographyFractureFracture mechanicsHigh strength steelMechanical propertiesSiliconTensile testingDeformation and fractureDuctility lossDynamic recrystallisationHigh-temperature ductilityHot tensile testingHot-tensile testsIncreasing temperaturesArticle0003384048000122-s2.0-848999256109094608Nanoscience & nanotechnologyMaterials science, multidisciplinaryMetallurgy & metallurgical engineeringHot Stamping; Advanced High Strength Steel; Microstructure
