Dendrite Grow up Relations with Cooling Speed

Abstract:

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.
