Single Crystal: A single crystal is a solid which has a regular geometric structure in which the complete solid is a crystal. and in this type of crystal atoms extend over the entire volume of solid with regular periodic arrangements. Single Crystal
Hume- Rothery Rule for the formation of a solid solution: There are some rules to form the substitutional solid solution and control the solubility in alloy system. If the size of solute and solvent along with the electron chemical nature are same then the substitutional solid solution is obtained. These rules govern the solid solution …

Fine-Grained Materials: This Fine-Grained Materials has a different type of properties due to the different type of sizes. There are some factors that grain size depends on, temperature up to the metal heated. Time of heating the metal in the furnace. Properties of grain size: Due to more hardness, the high tensile strength it is …

Grain Size: It is said to be a grain size with the diameter of the grain of granular material. and this is in the shape of irregular polycrystalline metal. in this, there are two structures i.e fine-grained metal and coarse-grained metal Smaller grain structure is called fine metal And larger structure is called coarse grain …

Grain and Grain Boundary: The Poly-Crystalline metals which has different types of shapes called grains. Poly-Crystalline metals are formed by crystals which are form by the transition of liquid to solid. The individual grains which are separated is called grain boundaries. In this, the grains are Regularly packed. This boundary is formed after complete solidification.
Alloys : The general alloys are made by mixing the metals in the molten state and purred into molds and solidify it. and in this, some are melted first and the other ingredient is added to it. to the making of the alloy is difficult at the time of melting process due to different metals …
Homogeneous and Heterogeneous Nucleation: Homogeneous: In this nucleation process, the nuclei process takes place at pure liquid metal and this grows up to solidification completes.
Direct solidification: It is known that the process occurs in a particular direction. In this to supply the liquid metal throughout freezing the feeder heads are used to design to solidify after a long time.
Master Alloy: The master alloy purpose is mainly to obtain certain chemical reaction or to get a chemical composition by adding the alloy or some of the mixtures of elements to a metal bath is known as the master alloy. This is also known as an alloy in which one or more elements added in …

The Difference between Pure Metal and Alloy is explained as follows: Pure metal: This metal has single phase materials that can form readily to a metallic bond which is done by composing of elements. Eg: Aluminium, copper etc… Due to the poor mechanical and physical properties, they are rarely used for engineering applications. These metals …
