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
## On the Mechanism of Crystal Growth from Undercooled Melts The mechanism of crystal growth from undercooled melts is studied experimentally by means of a simple capillary technique. Thymol and Na&&O,. 5 H,O are used as model substanc,es. Dislocation-free crystal faces of these compounds are obta
