A comparison of hot deformation behavior of high-Cr white cast iron and high-Cr white cast iron/low carbon steel laminate

Journal Article


Abstract


  • In order to study the plastic deformation characteristics of the brittle high-Cr white cast

    iron in upsetting process, and find out the mechanism for improving the formability of the

    cast iron within the laminated composite, the hot forging process of monolithic high-Cr

    white cast iron and high-Cr white cast iron/low carbon steel laminate is simulated by

    means of hot compression tests using Gleeble 3500 thermo mechanical simulator and

    professional plastic forming software DEFORM-3D. The results reveal that during hot

    compression process, the monolithic cast iron suffered severe barreling and cracking,

    whereas the cast iron layer within the laminate underwent large plastic deformation with

    barreling-free and crack-free. Such a significant improvement can be attributed to the

    simultaneous deformation of the cast iron together with the low carbon steel claddings,

    which is beneficial to relieving the stress in the cast iron and changing its deformation

    mode. Under the triaxial compressive stress state, the brittle high-Cr white cast iron within

    the laminate can flow like a ductile material at high temperatures and low strain rates.
