PROCEEDINGS OF THE IEEE‚ VOL. 70‚ NO. 5‚ MAY 1982 Silicon as a Mechanical Material KURT E. PETERSEN‚ MEMBER‚ IEEE Abstract-Single-crystal silicon is being increasingly employed in a variety of new commercial products not because of its well-established electronic properties‚ but rather because of its excellent mechanical properties. In addition‚ recent trends in the engineering literature indicate a growing interest in the use of silicon as a mechanical material with the ultimate goal of developing

observed the mechanical deformation process of different materials by three tests: tensile test‚ impact test‚ and fracture-toughness test. The materials evaluated in the tensile test were annealed 1045 steel‚ cold rolled 1045 steel‚ 2024-T4 aluminum and cast iron. 2024-T4 aluminum is concluded to be most ductile (25.7 % reduction in area) and cast iron the most brittle (123 MPa). Effects of cold rolling in 1045 steel are apparent‚ as it has the highest strength among the materials tested (402 MPa

MECHANICAL PROPERTIES OF FLUIDS 1 Torricelli’s barometer used mercury. Pascal duplicated it using French wine of density 984 kg m-3. Determine the height of the wine column for normal atmospheric pressure. 2 A vertical off-shore structure is built to withstand a maximum stress of 109 Pa. Is the structure suitable for putting up on top of an oil well in the ocean? Take the depth of the ocean to be roughly 3 km‚ and ignore ocean currents. 3 A hydraulic automobile lift is designed to lift cars with

Introduction Silicon carbide [409-21-2] (SiC) is a technologically important material that is one of the small number of unusual materials that were first created synthetically and then subsequently discovered in nature. Silicon carbide was first observed in its natural form in 1905 by the Nobel-prize-winning chemist Henri Moissan‚ who discovered it in the meteor that created the Diablo Canyon in Arizona. The transparent mineral‚ now known as

Speirs June 13‚ 2011 Professor Nalley Tungsten Paper Tungsten Tungsten is a gray-white metallic element that is stable and is very resistant to acids and bases. It does‚ however‚ oxidize in air‚ especially at higher temperatures Tungsten was discovered by Juan José and Fausto Elhuyar‚ Spanish chemists and brothers‚ in 1783 in samples of the mineral wolframite ((Fe‚ Mn)WO4). Tungsten was named from the Swedish words "tung sten" meaning "heavy stone." Tungsten ’s chemical symbol comes from its eariler

Engineering materials Choice of materials for a machine element depends very much on its properties‚ cost‚ availability and such other factors. It is therefore important to have some idea of the common engineering materials and their properties before learning the details of design procedure. Common engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals. Important ferrous metals for the present purpose

Physical Science Part A a) Materials A material is something which an object is made of. There are different types of materials and each type has its own properties. Materials can be natural or man-made. Natural materials can come from animals‚ plants or the ground. Man-made materials are artificially made using chemicals. There are different types of materials. Examples: Wood Rubber Cloth Metal Rock Plastics Glass Wood: Wood comes from trees. Wood can last

As my opening statement I would like to proudly say cobalt is an element which has its own gum. Though completely irrelevant to my report I enjoy it’s succulent‚ minty and long lasting flavor‚ because five… will stimulate your senses. I figure I might as well go into the greater details of cobalt as well as what it is and how it came to be. In the year 1739‚ Swedish chemist‚ Georg Brandt was trying to prove to his colleges that Bismuth‚ the element credited for its believed ability to turn glass
