Metals can be brittle in certain circumstances, and a metal can be made more brittle by alloying or by work hardening. They tend to be lustrous, ductile, malleable, and good conductors of electricity, while nonmetals are generally brittle (for solid nonmetals), lack lustre, and are insulators. It is a break in a brittle piece of metal that failed because stress exceeded cohesion. Their bonds are non-directional. Copyright © 2011. Aunt Adela, Rachel thought, was far too dried and brittle to risk any sharp contact with anything. Brittle materials absorb very small energy before fracture. Easily damaged or disrupted; fragile: a brittle friendship. ‘Niobium is a ductile and soft metal at elevated temperatures.’ ‘It is the most ductile and malleable of all metals.’ ‘Palladium is a relatively soft, silver-white metal that is both malleable and ductile.’ ‘Lutetium is a silvery white metal that is quite soft and ductile.’ Brittle Fracture is the sudden, very rapid cracking of equipment under stress where the material exhibited little or no evidence of ductility or plastic degradation before the fracture occurs. But, if it is pushed to the extreme, the material becomes brittle and fracturing is … Brittle definition: An object or substance that is brittle is hard but easily broken. b.

If the fractured pieces of a brittle fracture are fitted together, the … Since in ionic bonding every other atom is of opposite charge when a row of atoms attempts to slide past another row, positive atoms encounter positive atoms and negative atoms encounter negative atoms. Moreover, this same carburizing action of the fuel would at times go so far as to turn part of the metal into a true cast iron, so brittle that it could not be worked at all. Many steels become brittle at low temperatures (see ductile-brittle transition temperature), depending on their … having hardness and rigidity but little tensile strength; breaking readily with a comparatively smooth fracture, as glass.

How to use ductile in a sentence. The material fractures with no plastic deformation. Brittle materials are characterized by little deformation, poor capacity to resist impact and vibration of load, high compressive strength, and low tensile strength. Brittle definition, having hardness and rigidity but little tensile strength; breaking readily with a comparatively smooth fracture, as glass. In metals, the sliding of rows of atoms results in slip, which allows the metal to deform plastically instead of fracturing. a confection of melted sugar, usually with nuts, brittle when cooled: easily cracked, snapped, or broken; fragile, a crunchy sweet made with treacle and nuts. Her many style ticsâstacked one atop the otherâread as code for narcissism, self-indulgence, and brittle self-absorption. Most metals are not brittle but ductile and maleable. Brittle materials fail by sudden fracture (without any warning such as necking). easily damaged or destroyed; fragile; frail: lacking warmth, sensitivity, or compassion; aloof; self-centered: a self-possessed, cool, and rather brittle person. Having a tendency to break when subject to high stress. The battery has rubber jars which are brittle, and which are easily broken. A brittle fracture occurs with no macro deformation but failure occurs abruptly without localised reduction in area. This results in a huge electrodynamic repulsion which inhibits rows of ceramic atoms from sliding past other rows. Therefore, the more grain boundaries a metal has, the harder, more brittle, and less malleable it will be. This was about 46% of all the recorded Brittle's in the USA.

The College of Earth and Mineral Sciences is committed to making its websites accessible to all users, and welcomes comments or suggestions on access improvements. A brittle fracture is the fracture of a metallic object or other material without appreciable prior plastic deformation. Energy absorbed by ductile materials before fracture under tensile testing is more. Brittle materials include most ceramics and glasses (which do not deform plastically) and some polymers, such as PMMA and polystyrene. Menu. Still it comes to something in their likeness, but we will not talk of it and break off the chrystalsâthey are so brittle, then?
