Dendritic growth in metals occurs near the surface because there is often a higher concentration of impurities or foreign particles that can act as nucleation sites for crystal growth. Additionally, the surface energy is different from the bulk, making it more favorable for dendrites to form there. Thermal gradients are also more pronounced near the surface, promoting dendritic growth.

What is the surface metal raceway trade name?
One common trade name for surface metal raceway is "Wiremold".

Why it feels sticky when touching a cold metal surface?
When you touch a cold metal surface, moisture in the air can condense on the surface, creating a thin layer of water. This water can make the metal feel sticky when you touch it because your skin can't easily glide over the wet surface. The sensation of stickiness is due to the interaction between your skin, the water, and the metal surface.
How does surface tension relate to metal casting?
Surface tension in metal casting affects the flow and wetting of the molten metal on the mold surface. High surface tension can lead to poor flow and incomplete filling of the mold cavities, resulting in defects in the casting. Lowering surface tension through the addition of surfactants can improve the casting process by promoting better wetting and flow of the metal.
What mostly fills the periodic table?

mostly composite metal. or fiberglass
What exactly is case hardening?
Case hardening, also referred to as surface hardening is the process of hardening a surface of a metal. It is done by surfacing the metal surface with a layer of metal on top of it, in order to harden it.
