A dendrite in metallurgy is a characteristic tree-like structure of crystals growing as molten metal solidifies, the shape produced by faster growth along energetically favourable crystallographic directions. This dendritic growth has large consequences in regard to material properties.

Dendritic growth is perhaps the most common form of solidification especially in metals and other systems that freeze with relatively low entropies of transformation. Dendritic or branched growth in alloys generates microsegregation as well as other internal defects...

2011年1月12日 · What is a Dendritic Growth? A dendrite is a crystal with a tree-like branching structure. In the current context, we are interested in metallic dendrites formed when a metal, or an alloy of multiple metals, in liquid form freezes.

2015年1月1日 · Theoretical descriptions of dendritic growth combine transport theory (i.e., heat conduction, melt convection, and species diffusion) with microscopic interfacial processes, including capillarity, molecular interface attachment, and viscosity-limited melt mobility.

Dendritic growth is a coupling of two seemingly independent growth processes: the steady-state propagation of the dendrite main stem and the non-steady-state evolution of dendrite branches.

2017年7月1日 · The pattern selection of dendritic growth in the diffusion controlled regime under low-crystal-growth velocities was found to be given rise by the competition between interface energy anisotropy and interface kinetic anisotropy.

2004年3月31日 · 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.

2024年1月1日 · The pattern of dendritic growth is one of the key factors influencing the higher order organization and local connectivity in specific brain regions. As will be discussed in the following section, dendritic growth is regulated by multiple factors.

The solid takes on a tree-like form, called a dendrite, consisting of a pri- mary trunk growing along one of the six equivalent h100i directions of the crystal, with secondary arms in the four conjugate h100i directions appear-

This review summarizes these studies and pays the most attention to the stable mode of dendritic growth, which is selected by the selection/stability parameter and the melt undercooling condition.
