The microsructural and content of δ ferrite in non-equilibrium solidified 0Cr18Ni9 austenitic stainless steel is studied by the coin with the circulating water. The solidified microstructure of the residual δ ferrite in different cooling rate is that during the course of solid-state transformation, austenite grows into ferrite gradually; corresponding to the increase of cooling rate, the microsructural of ferrite is skeletal, network, strip and block. The experiment demonstrates that the content of the residual δ ferrite is increase under the increase of the cooling rate. |
