Test engineers, TK Pedergrass and Dave McIntosh, are growing multiple dendrites in an undercooled melt of ultra pure succinonitrile (SCN). Images and temperature measurements will give Dr. Christoph Beckerman, the EDSE Principal Investigator, information on the microstructural evolution of and thermal interactions between several equiaxed crystals growing dendritically. This benchmark data will be used to test and develop equiaxed dendritic solidification models. The monitors show both the 4 stinger and 2 stinger chambers that are placed in the isothermal bath for testing.
