Dendritic Growth In Metals. Grains which are orientated with the 100 direction close to the direction of heat flow will grow fastest and stifle the growth of other grains leading to a columnar microstructure. Dendritic growth is quite commonly observed in alloys. And these grains turns into the spikes of grains and these spikes turns into the grain branches oriented inside the mold. Dendrites are developed in both single one-component and multi-component systems.
This dendritic growth has large consequences in regards to material properties. DENDRITIC GROWTH IN PURE METALS A dendritic crystalline growth occurs when the liquid-solid interface moves into a. Whats most important is that the shape size and speed of growth of these dendrites are all factors that profoundly influence the final properties of cast and welded metals. The study of the formation of metallic. Dendritic growth is a fundamental crystal growth phenomenon accompanying most casting and solidification processes and occasionally occurring during the growth of single crystals where it is detrimental to crystalline quality. In chemistry a dendrite is a crystal that branches into two parts during growth.

When a dendritic structure forms the dendrite arms grow parallel to the favourable growth directions normally 100 in cubic metals. And these grains turns into the spikes of grains and these spikes turns into the grain branches oriented inside the mold. In fact almost all freshly crystallized alloys are composed of many thousands or even millions of dendritic crystals all stuck together.
