Sphc Steel

Confocal Laser Scanning Microscopy in situ observation of the solidification process of SPHC Steel and SPHC steel solidification structure changes. The results showed that: SPHC steel in the molten state, the surface of the melt flow of black substance; and with the temperature decreasing, SPHC gradually solidified dendrites continue to grow, increasing new nuclear the dendritic structure continue to refine, to δ-Fe and γ-Fe crystalline phase from the melt.

Using confocal laser microscope with an infrared heater for 45 steel under different rate of solidification dendrite formation in the process of in situ observation, in the melt solidification phase has different cooling rate the cooling of dendrite formation, analysis of cooling rate on final solidified structure. Results show that with the reduction of temperature in the solidification process dendrite growth continuously, new nuclear has been formed, with the speeding up of the cooling rate, the dendritic structure refinement.
