Abstract：In order to better understanding of the solidification process, it was inferred that the solidification mode of 06Cr19Ni10 austenitic stainless steel from calculating of chromium equivalent and nickel equivalent, and using the technique of differential thermal analysis (DTA) 06Cr19Ni10 austenitic stainless steel in 10 and 30℃/min heating and cooling rate. The endothermic peak and exothermic peak of DTA curve of solidification process was studied, and the microstructure were analyzed by laser scanning confocal microscopy (LSCM) and scanning electron microscopy (SEM). The results show that: the solidification mode 06Cr19Ni10 austenitic stainless steel is the FA type; austenite nucleation rate increases under increasing of cooling rate, the form of the residual δ ferrite is finer dispersion.
