Dendrites of tin were pulled from a supercooled melt in 8 fashion simil8r to semiconductor dendrite growth. The growth morphology of these tin dendrites ~8s determined snd the growth orient8tion found to be 12' eway from the [llO] direction towards the [OOl] direction. The effect on the growth direc
The theory of alloy dendritic growth at large undercoolings is extended to include the effect of growth rate dependent partition coefficient on the growth rate, tip radius and composition of dendrites. Three distinct behaviors are observed depending on the value of the dimensionless rate 0). For sma
The theory of dendritic growth into undercooled alloy melts is extended to the case of large undercoolings, i.e. to high growth rates. This is done by applying the results of the complete stability analysis of a plane interface to the tip of an Ivantsov dendrite. For small P&let numbers this model c
