Brinell Hardness Testers
BRINELL HARDNESS TESTERS BRINELL HARDNESS TESTING The Brinell scale characterizes the indentation hardness of Common values materials through the scale of penetration of an indentor, The standard format for specifying tests can be seen in the loaded on a material test-piece. example "HBW 10/3000". "HBW" means that a tungsten carbide (from the chemical symbol for tungsten) ball Proposed by Swedish engineer Johan August Brinell in indentor was used, as opposed to "HBS", which means a 1900, it was the first widely used and standardized hardened steel ball. The "10" is the ball diameter in hardness test in engineering and metallurgy. millimeters. The "3000" is the force in kilograms force. The typical tests use a 10, 5, 2.5 or 1mm diameter steel Standards ball as an indentor with a test force starting at 1kgf up to • European & international EN ISO 6506-1 3,000kgf (29 kN) force. For softer materials, a lower force • American ASTM E10-08 is used; for harder materials, a tungsten carbide ball is substituted for the steel ball. After the impression is made, a measurement of the diameter of the resulting round impression (d) is taken. It is measured to plus or minus 0.05mm using a low-magnification microscope. The hardness is calculated by dividing the load by the area of the curved surface of the indention, (the area of a hemispherical surface is arrived at by multiplying the square of the diameter by 3.14159 and then dividing by 2). 56 BRINELL HARDNESS TESTING BRINELL HARDNESS TESTERS NEXUS 3000 SERIES BRINELL OPTICAL SCANNING SYSTEM HB100 BRINELL

Mohs Scale of Mineral Hardness
Mohs scale of mineral hardness From Wikipedia, the free encyclopedia The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created in 1812 by the German geologist and mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science.[1] The method of comparing hardness by seeing which minerals can scratch others, however, is of great antiquity, having first been mentioned by Theophrastus in his treatise On Stones, circa 300 BC, followed by Pliny the Elder in his Naturalis Historia, circa 77 AD.[2][3][4] Contents [hide] 1 Minerals 2 Intermediate hardness 3 Hardness (Vickers) 4 See also 5 References [edit]Minerals The Mohs scale of mineral hardness is based on the ability of one natural sample of matter to scratch another. The samples of matter used by Mohs are all minerals. Minerals are pure substances found in nature. Rocks are made up of one or more minerals.[5] As the hardest known naturally occurring substance when the scale was designed, diamonds are at the top of the scale. The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, and/or the softest material that can scratch the given material. For example, if some material is scratched by apatite but not by fluorite, its hardness on the Mohs scale would fall between 4 and 5.[6] The Mohs scale is a purely ordinal scale. For example, corundum (9) is twice as hard as topaz (8), but diamond (10) is four times as hard as corundum.

Portable Hardness Testers
PORTABLE HARDNESS TESTERS PORTABLE HARDNESS TESTING INNOVATEST offers a wide range of portable hardness testing instruments. Most of the common testing methods are represented in this catalogue. Portable instruments often offer an excellent alternative if the workpiece is too heavy or too large to be tested on a bench hardness tester. Reliability Its often understand by the public that portable hardness testing instruments are less reliable or less accurate than bench type hardness testers. This however is a misunderstanding. Portable hardness testers, considering to be manufactured according to the applicable standards, are as accurate as bench hardness tester. The importance of portable instruments is that they should be applied in a correct manner, respecting the testing conditions as advised for the praticular testing method. Misuse is often laying on the basis of wrong values obtained by portable testing instruments. Another recent problem is that there are many cheap, poor quality portable testing instruments available on the market. Such instruments offer promising specifications which in many cases cannot be reached or can be reached but only for a short period of the ‘’life time’’ of such instrument. It is strongly recommended to buy portable testing instruments that are covered by a decent service system offering regular checks and which have a proven track record of reliability and quality. Portable testing methods Most common testing methods are the Leeb hardness, rebound technology, or the UCI ultrasonic hardness test. While the rebound technology conforms to the ASTM and DIN standards, UCI offers the advantage of being more suitable for light weighted and thin components.

Properties of Materials: More Than Physical and Chemical
Properties of materials: more than physical and chemical Structural properties These aren’t really ‘properties’ – more like definitions that relate to what’s under the hood. The goal here is to relate structure to properties. Composition The kinds and relative count of elements, ions or other constituents in a material; chemical formula, percent in an alloy, etc. Note that a single composition can have different structures, for instance allotropes of sulfur or polymorphs in iron-carbon systems. The basic starting point is: Composition Bonding Metals metallic elements metallic Ceramics metals + nonmetals ionic & covalent Polymers carbon, hydrogen covalent Crystal structure Atomic scale order; the manner in which atoms or ions are spatially arranged. It is defined in terms of unit cell geometry. A material with long- range order is called crystalline (contrasted with amorphous). Microstructure The structural features that can be seen using a microscope, but seldom with the naked eye; ranges from glassy to crystalline; includes grain boundaries and phase structures. Physical properties These are the standard properties that we teach in chemistry class. State Solid, liquid or gas; not as simple as it may seem. Density Mass of a material per unit volume. Low density, high strength materials are desirable for manufacturing aircraft and sporting equipment. Magnetism The physical attraction for iron, inherent in a material or induced by moving electric fields. Iron, cobalt, nickel and gadolinium are inherently ferromagnetic. Solubility The maximum amount of a solute that can be added to a solvent. Solubility is complex in some solid materials, for instance the ones that form eutectic mixtures; a good starting point to discuss complex phase diagrams.

Antimony Recycling in the United States in 2000
U.S. Department of the Interior U.S. Geological Survey Antimony Recycling in the United States in 2000 By James F. Carlin, Jr. U.S. GEOLOGICAL SURVEY CIRCULAR 1196–Q FLOW STUDIES FOR RECYCLING METAL COMMODITIES IN THE UNITED STATES III FOREWORD As world population increases and the world economy expands, so does the de- mand for natural resources. An accurate assessment of the Nation’s mineral resources must include not only the resources available in the ground but also those that become available through recycling. Supplying this information to decisionmakers is an essen- tial part of the USGS commitment to providing the science that society needs to meet natural resource and environmental challenges. The U.S. Geological Survey is authorized by Congress to collect, analyze, and disseminate data on the domestic and international supply of and demand for minerals essential to the U.S. economy and national security. This information on mineral oc- currence, production, use, and recycling helps policymakers manage resources wisely. USGS Circular 1196, “Flow Studies for Recycling Metal Commodities in the United States,” presents the results of flow studies for recycling 26 metal commodi- ties, from aluminum to zinc. These metals are a key component of the U.S. economy. Overall, recycling accounts for more than half of the U.S. metal supply by weight and roughly 40 percent by value. Charles G.
