3. Instead of being strong and resilient, bones become weak and brittle. Meaning of Brittle. Dictionary ! tlest 1. a. Lacking warmth of feeling; cold. In metals, the sliding of rows of atoms results in slip, which allows the metal to deform plastically instead of fracturing. ... with the 10% specimen being brittle and the 100% specimen being ductile. b. A brittle fracture occurs with no macro deformation but failure occurs abruptly without localised reduction in area. 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. How to use ductile in a sentence. Brittle material breaks while little to no energy is absorbed when stressed. Annealed 1018 steel is a low-strength BCC steel, which exhibits a ductile-brittle transition as shown above in the general behavior schematic. The battery has rubber jars which are brittle, and which are easily broken. The Brittle family name was found in the USA, the UK, Canada, and Scotland between 1840 and 1920. In metals, their metallic bonds allow the atoms to slide past each other easily. Brittle egos are bolstered less by what they love about themselves than what they find contemptible in others. See more. Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012. If the fractured pieces of a brittle fracture are fitted together, the … Metalloids are brittle, lustrous metallic elements that exhibit semiconductive properties. Synonym Discussion of ductile. 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. Therefore, the more grain boundaries a metal has, the harder, more brittle, and less malleable it will be. (6) Osteoporosis is a disease in which bones become thin, brittle and easily broken. At high loads, the distortion is … Overview. Brittle definition: An object or substance that is brittle is hard but easily broken. A brittle material is one that will break as opposed to bending. Please send comments or suggestions on accessibility to the site editor. Unlike metals, they are neither malleable nor ductile.

Ltd. 1979, 1986 © HarperCollins Still it comes to something in their likeness, but we will not talk of it and break off the chrystals—they are so brittle, then? 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. The material fractures with no plastic deformation. Typically, there will be a large audible snap sound when the brittle material breaks. ‘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.’ Brittle diabetes is a severe form of diabetes.Also called labile diabetes, this condition causes unpredictable swings in blood sugar (glucose) levels.
