Thermal Deformation Behavior and Microstructure Evolution of High-Cr Cast Iron(HCCI)/Low Carbon Steel(LCS)
Through the high chromium cast iron/low carbon steel metal carbon steel sleeve constraint,the layered composite material by thermal compression connection process with high chromium cast iron(HCCI)as the inner layer and low carbon steel(LCS)as the outer layers on a Gleeble-3800 thermal simulator at the temperature of 1050 ℃-1150 ℃ and the strain rate of 0.05 s-1,0.5 s-1,5 s-1 was prepared,and the effects of hot pressing process of low carbon steel coating on the microstructure and mechanical properties of high chromium cast iron were systematically studied.It is found that the two materials achieve the metallurgical combination under thermal compression conditions without affecting the original properties of the substrate.The high chromium cast iron achieves good thermoplastic deformation,improves the problem of low material toughness,and improves the workability of the material.
