In a demonstration, a metal sphere dropped on amorphous steel bounced significantly longer than the same metal sphere dropped on crystalline steel. [ 4 ] The lack of grain boundaries in a metallic glass eliminates grain-boundary corrosion—a common problem in high-strength alloys produced by precipitation hardening and sensitized stainless steels.
The Mazda MX-5 is a lightweight two-person sports car manufactured and marketed by Mazda with a front mid-engine, rear-wheel-drive layout.The convertible is marketed as the Mazda Roadster (マツダ・ロードスター, Matsuda Rōdosutā) or Eunos Roadster (ユーノス・ロードスター, Yūnosu Rōdosutā) in Japan, and as the Mazda Miata (/ m i ˈ ɑː t ə /) in the United States, and ...
The term noble metal (also for elements) is commonly used in opposition to base metal. Noble metals are less reactive, resistant to corrosion or oxidation, [49] unlike most base metals. They tend to be precious metals, often due to perceived rarity. Examples include gold, platinum, silver, rhodium, iridium, and palladium.
Bimetal refers to an object that is composed of two separate metals joined together. Instead of being a mixture of two or more metals, like alloys, bimetallic objects consist of layers of different metals. Trimetal and tetrametal refer to objects composed of three and four separate metals respectively. A bimetal bar is usually made of brass and ...
Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of Fe Cr 2 O 4.It is an oxide mineral belonging to the spinel group.
Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). [ 1 ] The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure .
The store design alternative thinking and strategy in China has been to locate stores to facilitate access for non-car owning customers. [62] In some locations in China, IKEA stores can be found not in the usual suburban or near airport locations like other countries, but rather places such as downtown shopping centres with a 'mini-IKEA' store ...
