What is grain structure in materials science?
Grain structure of a solid is an arrangement of differently oriented grains, surrounded by grain boundaries. Formation of a boundary between two grains may be imagined as a result of rotation of crystal lattice of one of them about a specific axis.
How would you describe a grain?
A grain is a small, hard, dry seed – with or without an attached hull or fruit layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and legumes.
What is grain in crystal structure?
A crystallite is a small or even microscopic crystal which forms, for example, during the cooling of many materials. Crystallites are also referred to as grains.
What are grains in metals?
grain, in metallurgy, any of the crystallites (small crystals or grains) of varying, randomly distributed, small sizes that compose a solid metal. Randomly oriented, the grains contact each other at surfaces called grain boundaries.
What is a grain in metal forming?
Grain direction is a term used to describe the rolling direction of metal after being manufactured into sheet, plate or coil. This manufacturing method is where hot metal is compressed through rollers and forced into shape, elongating the crystals in the process.
Is a seed a grain?
A seed is not a grain – they have much different levels of nutrition and digestibility. A germinated or sprouted seed is even less similar, having gone through a complete physical and chemical transformation during and after germination – like a caterpillar emerging from the cocoon as a butterfly – everything changes.
Is rice a seed or grain?
Rice is a small edible seed that is cultivated from grain plants around the world. It nourishes billions of people each day, and thousands of varieties exist. Nutritionally, rice provides primarily carbs and a little protein with few other nutrients.
What is the meaning of grain of sand?
1. a. Small loose grains of worn or disintegrated rock. b. Geology A sedimentary material, finer than a granule and coarser than silt, with grains between 0.06 and 2.0 millimeters in diameter.
What does it mean to be grained?
1 : resembling or having some characteristic of grain : not smooth or fine.
What is grain size in material science?
Grain size refers to the dimensions of grains or crystals in a polycrystalline metal exclusive of twinned regions and subregions when present.
Is a grain a single crystal?
"A grain is a single crystal in all form polycrystalline as well as in single crystal." No. Typically, a grain exhibits several crystals with orientations distinct being each crystal with proper contour, several times called wall-domain. But, at rare exceptions a grain can be a single crystal.
What is the grain structure forming process?
When a metal solidifies from the molten state, millions of tiny crystals start to grow. The longer the metal takes to cool the larger the crystals grow. These crystals form the grains in the solid metal. Each grain is a distinct crystal with its own orientation.
What is grain and grain boundary?
These individual crystals are called"grains." In any one grain, all atoms are arranged with one particular orientation and one particular pattern. The juncture between adjacent grains is called a "grain boundary." The grain boundary is a transition region in which some atoms are not exactly aligned with either grain.
What is grain size in material science?
Grain size refers to the dimensions of grains or crystals in a polycrystalline metal exclusive of twinned regions and subregions when present.
How does the structure of grain effect the properties of a material?
Grain size has a measurable effect on most mechanical properties. For example, at room temperature, hardness, yield strength, tensile strength, fatigue strength and impact strength all increase with decreasing grain size.

Why does a polycrystal not have a periodic arrangement?
In the final block of solid material, each of the small crystals (called “ grains “) is a true crystal with a periodic arrangement of atoms, but the whole polycrystal does not have a periodic arrangement of atoms, because the periodic pattern is broken at the grain boundaries.
Why is grain size important for creep?
A larger grain size is preferred for improved high-temperature creep properties. Creep is the permanent deformation that increases with time under constant load or stress. Creep becomes progressively easier with increasing temperature. Grain Boundaries.
What are crystalline solids made of?
Most crystalline solids are composed of a collection of many small crystals or grains of varying size and orientation. These have random crystallographic orientations. Grains and Boundaries Source: U.S. Department of Energy, Material Science. DOE Fundamentals Handbook, Volume 1 and 2. January 1993.
What is grain boundary?
The grain boundary refers to the outside area of a grain that separates it from the other grains. The grain boundaries separate variously-oriented crystal regions (polycrystalline) in which the crystal structures are identical. Grain boundaries are 2D defects in the crystal structure, and tend to decrease the electrical and thermal conductivity ...
How do grain boundaries affect dislocation?
On the other hand, grain boundaries disrupt the motion of dislocations through a material. Dislocation propagation is impeded because of the stress field of the grain boundary defect region and the lack of slip planes and slip directions and overall alignment across the boundaries.
What is grain in metal?
Grains, also known as crystallites, are small or even microscopic crystals which form, for example, during the cooling of many materials (crystallization). A very important feature of a metal is the average size of the grain. The size of the grain determines the properties of the metal. For example, smaller grain size increases tensile strength ...
How to find random orientation?
Random orientation can be obtained by crossrolling the material. If such a sample were rolled sufficiently in one direction, it might developa grain-oriented structure in the rolling direction. This is called preferred orientation. In many cases, preferred orientation is very desirable, but in other instances, it can be most harmful.

What is grain per gallon?
One application of the unit "grain" is in the measurement of water hardness, which is measured in grains per gallon or Clark degrees. In a more detailed sense, grains per gallon can be described as one part of grain per 58,000 parts of water. Water is considered soft as it falls as rain. However, it collects particles like magnesium, calcium, lead, ...
What does "grains" mean in water?
What Does Grains Mean? Grains, in terms of water hardness measurement, refer to the unit of weight that is equivalent to 1/7000th of a pound. In an average household with four members, a water hardness level of approximately 7 grains per gallon (gpg) is equivalent to 66 kilograms of rock in the water per year. Advertisement.
What is grainy water?
Grainy water also leaves stains and impurities on clothes, dishes and other things. Additionally, hard or grainy water is more abrasive, has less capacity to heat and may cause corrosion and scale buildup on water pipes, heaters and other plumbing fixtures.
Is water soft or hard?
Water is considered soft as it falls as rain. However, it collects particles like magnesium, calcium, lead, iron, etc. as it passes through soil and rocks. Due to the high grain levels per parts of water, some abilities are reduced, like the ability to clean and produce soap suds.
