摘要：

The effects of addition of ZrC particles on microstructure and mechanical properties of a low carbon manganese steel treaed by deformation induced ferrite transformation(DIFT) were investigated by unidirectional compression thermal simulating experiment on a Gleeble-1500 machine, and the plain C-Mn steel plate with ultra-fine grained ferrite was fabricated. The results show that adding ZrC particles with diameter less-than 1.0 μm strengthens the steel by multiplication of dislocations in matrix and ferrite grain refinement due to non-uniform deformation at ZrC/austenite interface. The fine microstructure with a grain size of 3.9 μm is obtained for the plate with thickness of 9 mm fabricated using the low carbon mangnese steel containing 0.5 vol%. ZrC particles with diameter of 0.4 μm. Tensile strength of the steel increases by 51% compared with that of commercial steel 20Mn2.
