Contact Us, Privacy & Legal Statements | Copyright Information See Synonyms at fragile. ‘As it was fractured before it left the bell tower and was gently lowered, it is likely the brittle metal broke in the sudden change of temperature from scorching heat to cold as the flames were doused with water.’ ‘However, the rubbery material was brittle and broke too easily.’ 2217 Earth and Engineering Sciences Building, University Park, Pennsylvania 16802 (adjective) A reputation for being brittle and aloof. 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. Even the denser rocks are much more porous and brittle than meteorites from similar asteroids that have been found on Earth. Virginia had the highest population of Brittle families in 1840. What are the 5 metallic properties? You may be asking: why are ceramics so much more brittle than metals? 1 (of 2) 1845-1846. 3. X-ray diffraction analysis is able to detect a thin film of deformed metal at the fracture surfaces. The American Heritage® Science Dictionary • BRITTLE (adjective) The adjective BRITTLE has 3 senses: 1. having little elasticity; hence easily cracked or fractured or snapped. ‘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 nails tend to split, peel, and break easily. If the fractured pieces of a brittle fracture are fitted together, the … A brittle fracture is the fracture of a metallic object or other material without appreciable prior plastic deformation. fragile or easily broken. However during later times after the Industrial Age, craftsmen were able to achieve higher temperatures for impurity removal, and they further improved upon the process by mixing carbon that made the brittle iron stronger. Enrich your vocabulary with the English Definition … (7) For the pumpkin seed brittle , in a small covered saucepan, bring the sugar and water to a boil. 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. Brittle material breaks while little to no energy is absorbed when stressed. Overview. Dictionary !

Malleability vs. Ductility While malleability is the property of a metal that allows it to deform under compression, ductility is the property of a metal that allows it to stretch without damage. Brittle materials fail by sudden fracture (without any warning such as necking). Other articles where Brittleness is discussed: ceramic composition and properties: Brittleness: Unlike most metals, nearly all ceramics are brittle at room temperature; i.e., when subjected to tension, they fail suddenly, with little or no plastic deformation prior to fracture.
