The game of tug-of-war provides a good example of tensile strength being applied to a rope. Material description - what do your senses tell you. As discussed earlier, at a given test temperature a metal may be ductile in the tension test and brittle in an impact test. I think brittle can be the opposite of malleable. Login to reply the answers Post; Douglas. Antonyms for brittle. 3. brittle adjective. So I have a slip plane in a metal, and the crack as you see parts of the metal shift over stretching out rather than having the crack propagate all the way through the metal … the look and feel.Some are directly related to their mechanical and physical properties - density/heavy, cold/thermal conductivity, hard/impact resistance etc. At a particular temperature, a ductile material exhibits substantial plastic deformation under external loading, while a brittle material breaks with negligible plastic deformation under tensile stress. can be performed on ductile materials. A brittle metal will absorb a small amount of energy when impact tested, a tough ductile metal a large amount of energy. Also includes alloys which are a mixture of a metal and another element (usually another metal) to give new properties. ... brittle - (of metal or glass) not annealed and consequently easily cracked or fractured. The opposite (ductile) means it will deform before it breaks. BCC and HCP metals are more brittle than FCC metals. Brittle fracture is generally characterized by little or no deformation of the metal in the vicinity of the fracture, or by a distinctive fracture having bright crystalline appearing facets. Wood is hard compared to rubber, but soft compared to steel. Soft means it will give way pretty easily. Hardness is the ability of a material to resist plastic deformation. That is, its ability to resist scratching or denting. Brittle: A material which breaks without when force is applied on it beyond a certain limit (fracture point), withoutdeformation. ... Brittleness is the property opposite of plasticity or ductility. We will talk more about ductile materials in the next section. Considerable confusion has, unfortunately, existed about the nature of the behav- ior that is the opposite of brittle. 0 0 0. These terms are all relative. The mechanical properties of metals determine the range of usefulness of the metal and establish the service that can be expected. factory at normal temperatures. Metal atoms can easily slide along what are called slip planes to blunt the crack. Examples of metals include:- copper, aluminium, steels (mild steel, stainless steel, high and medium carbon steel, mild steel), silver, gold, zinc. Typical brittle materials: glass, concrete, ceramics, stone, gray cast iron; Ductility. Lv 7. Diamonds are brittle precisely because they are so hard! Hard means it will resist being stretched or bent. tlest 1. a. whereby a material can be plastic deformed by elongation without fracture malleable is the quality of a metal which can be produced into thin sheets. Brittle materials absorb very small energy before fracture.
A brittle material is also known as a material having low ductility. aluminium alloy, solder, magnesium alloy, brass, bronze, zinc alloy. e.g. Synonyms for brittle in Free Thesaurus. A brittle metal is one than cannot be visibly deformed … an element that lacks most of the properties of a metal In general, most nonmetals are poor conductors of electric current and heat. Various metal forming operations (such as rolling, forging, drawing, bending, etc.) These properties determine how you you interact with the products i.e. Metals like gold, copper, lead and silver are the opposite - ductile. Alloys such as medium and high carbon steel, cast iron and tool steel are brittle. Need a hard metal that is not brittle 21 posts ... (the opposite of brittle). Forming operations cannot be easily performed on brittle materials. 7 years ago. Brittle means something breaks very suddenly. The elastic stage is followed by immediate fracture.
