WebWhich is why X-Ray spectroscopy is very useful technique for characterization of different types of materials. We can easily calculate the size of particles from Scherrer formula given: Scherrer Formula: Dp = … WebA nanocrystalline copper–tantalum alloy with high strength and extremely high-temperature creep resistance is achieved via a processing method that creates clusters of atoms within the alloy that pin grain boundaries. Reducing the grain size of a metal is one way of increasing its strength, but it can often have detrimental effects on other mechanical …
Crystals are materials that have a repeating arrangement of atoms. Single crystals, like gemstones, have a single grain so the periodic array of atoms is never interrupted. Polycrystals, like metal, have many grains which are usually too small to see. Crystal structure is one of the most basic properties of a material. See more Boy, that sounds fancy. A periodic arrangement of atoms just means that the atoms repeat in some pattern. Usually, this pattern is super simple. Think back to school, when you learned about solids, liquids, and gasses. … See more When we talk about crystal structures, we define a unit cell. The unit cell is the basic repeating block of a crystal. To define a unit cell, we need to use a lattice and basis. The lattice is … See more Now we can get to crystal grains. Grains are the reason why most objects don’t “look” like a crystal to you. You can think of each grain like a crystal of its own. Each one of those areas is a crystal with a certain orientation, … See more If you look at the crystal structures of each element, you’ll notice that some structures are especially common.
