What is the chemical definition of brittleness? , BS Chemistry, 1967. Brittleness is not a chemical property but a physical property. A material is brittle when it is stressed and does not deform, but breaks. A brittle material often makes a snap or pop when it breaks. In Materials Science, a material is deemed brittle when there is no plastic deformation before failure when the material is stressed.

- Metal Definition: ​. A substance with high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions (cations). Metals are otherwise defined according to their position on the Periodic Table, including groupings as alkali metals, alkaline earth metals, transition metals, and rare earth metals. Article.

BRITTLE FRACTURE Cracks propagate rapidly. Brittle failure results from cleavage (splitting along definite planes). Ductile fracture is better than brittle fracture, because ductile fracture occurs over a period of time, whereas brittle fracture is fast, and can occur (with flaws) at lower stress levels than a ductile fracture.

- Crystal structure. Crystal structure. (Science: chemistry) The configuration in which atoms are arranged in a material. These arrangements have a direct effect on the physical properties of the material. These arrangements commonly take the form of cubes, rectangular solids, hexagonal solids. Etc.

brittleness Tendency of a material to fracture or fail upon the application of a relatively small amount of force, impact, or shock. Opposite of toughness. You need to know the brittleness of everything you work with and not apply to much force to it if it can't take it. 17 people found this helpful.

Brittle-Ductile Transition Temperature The brittle-ductile transition temperature itself strongly depends on the morphology and the chain structure of the polymer. Polymers with a flexible backbone tend to have a much lower brittle-ductile transition temperature than polymers with a stiff backbone.

Brittle Diabetes (Labile Diabetes) Brittle diabetes is a sub-type of type 1 diabetes. Brittle diabetes mellitus (or labile diabetes) is a term used to describe particularly hard to control type 1 diabetes. Those people who have brittle diabetes will experience frequent, extreme swings in blood glucose levels, causing hyperglycemia or hypoglycemia.

Ionic compound Ionic compounds typically have high melting and boiling points, and are hard and brittle. As solids they are almost always electrically insulating, but when melted or dissolved they become highly conductive, because the ions are mobilized.

Glass transition Glass transition. The glass–liquid transition or glass transition for short is the reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle glassy state into a viscous or rubbery state as the temperature is increased.

- In chemistry, a chemical substance is a form of matter that has constant chemical composition and characteristic properties. It cannot be separated into components without breaking chemical bonds. Chemical substances can be solids, liquids, gases, or plasma.

- Brittleness is the property of a metal that allows little bending or deformation without shattering. In other words, a brittle metal is apt to break or crack without change of shape. Because structural metals are often subjected to shock loads, brittleness is not a very desirable property. Cast iron, cast aluminum, and very hard steel are brittle metals. Malleability. A metal that can be hammered, rolled, or pressed into various shapes without cracking or breaking or other detrimental effects is said to be malleable. This property is necessary in sheet metal that is to be worked into curved shapes such as cowlings, fairings, and wing tips. Copper is one example of a malleable metal. Ductility

Diamagnetic Definition and Diamagnetism Examples Diamagnetic Definition (Diamagnetism) In chemistry and physics, to be diamagnetic indicates that a substance contains no unpaired electrons and, thus, is not attracted to a magnetic field. Diamagnetism is a quantum mechanical effect that is found in all materials, but for a substance to be termed diamagnetic it needs to be the only contribution to the matter's magnetic effect.
