I wonder if there can be any dendrites of primary phase formed in hyper-eutectic alloys.
Can somebody help with examples?

Dendrites are small crystalline structures that form during the solidification process of hyper-eutectic alloys. They are usually branching and tree-like in shape, and are formed when the alloy cools and solidifies at a certain temperature.
Dendrites play a crucial role in determining the microstructure and properties of hyper-eutectic alloys. The size, shape, and distribution of dendrites can affect the mechanical, thermal, and electrical properties of the alloy.
Dendrites act as nucleation sites during solidification, meaning they provide a starting point for the alloy to solidify. They also influence the cooling rate and direction of solidification, which can affect the final microstructure of the alloy.
Yes, the formation and growth of dendrites can be controlled through various methods such as alloy composition, cooling rate, and processing techniques. By controlling dendrites, engineers and scientists can tailor the properties of the alloy for specific applications.
Dendrites can cause defects and inhomogeneities in the microstructure of hyper-eutectic alloys, which can negatively impact the mechanical and physical properties of the alloy. This can pose challenges for manufacturers in producing high-quality and consistent alloys.
