ASTM B703-10 用阿诺德仪表测定粉末表观密度的标准试验方法

The apparent density is an important measure of a material characteristic of the powder that is useful to the powder producers and powder users in determining quality and lot to lot consistency. This test method is applicable to free-flowing and non-free-flowing metal powders, lubricated powder mixtures and metal compounds. 5.3 The apparent density of a lubricated metal powder mixture may be different when a quantity settles after falling into the die cavity during automatic compacting as compared with the value obtained from a measurement taken in the laboratory under controlled test conditions. 5.4 This test method simulates the action of the feed shoe on a powder compacting press and gives an apparent density value that closely approximates the apparent density of the powder in the die cavity after the production filling operation. 5.5 Knowledge of this apparent density value for the final lubricated production powder mixture is very helpful to the powder metallurgy (PM) parts fabricator to set the compression ratios for fixed fill die cavity tooling. 5.6 The values of apparent density obtained on metal powders with this test method are approximately 0.2 g/cm3 higher than those obtained using the Hall Funnel, Test Method B212, the Carney Funnel, Test Method B417; or the Scott Volumeter, Test Method B329. 5.7 This test method may be part of a purchase agreement between the powder supplier and PM parts producer, or it may be an internal quality control test for either party.1.1 This test method covers a quantitative laboratory procedure for determining the apparent density of both free-flowing and non-free-flowing metal powders, lubricated metal powder mixtures, and powder compounds. 1.2 With the exception of the values for mass, volume, and density, for which the use of the gram and the cubic centimetre units is the long-standing industry practice, the values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM E159-10 钴、铜、钨和铁粉用氢质量损失(氢还原减重)的标准试验方法

The oxygen content of a powder affects both its green and sintered properties. Hydrogen loss is a term widely used in the powder metallurgy industry even though the measurement represents an approximate oxygen content of the powder. Oxygen is the most common hydrogen-reducible constituent of metal powders, and this procedure may be used as a measure of oxygen, reducible under the test conditions, if other interfering elements are absent.1.1 This test method covers the determination of the mass of hydrogen-reducible constituents in the following metal powders: cobalt, copper, iron, and tungsten. 1.2 This test method is useful for cobalt, copper, and iron powders in the range from 0.05 to 3.0 % oxygen, and for tungsten powder in the range from 0.01 to 0.50 % oxygen. 1.3 This test method does not measure the oxygen contained in oxides such as silicon oxide (SiO2), aluminum oxide (Al2O3), magnesium oxide (MgO), calcium oxide (CaO), titanium dioxide (TiO2), etc. that are not reduced by hydrogen at the test temperatures. 1.4 For total oxygen content, vacuum or inert gas fusion methods are available (see Test Methods E1019). 1.5 The values stated in SI units are to be regarded as the standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM E194-10 铜和铁粉中的不溶酸成分的标准试验方法

The purpose of this test method is to determine the amount of gangue, refractory, inert, etc., materials, that may adversely affect compacting tools and sintered properties of components formed from copper and iron powders. The insoluble matter consists of those nonmetallic substances that do not dissolve in the mineral acid used to dissolve the metal. In copper powder, which is treated with nitric acid, the acid-insoluble matter includes silica, insoluble silicates, alumina, clays, and other refractory materials that may be introduced either as impurities in the raw material or from the furnace lining, fuel, etc.; lead sulfate may also be present. In iron powder, which is treated with hydrochloric acid, the insoluble matter may include carbides in addition to the substances listed above. The test method excludes insoluble material that is volatile at the ignition temperature specified.1.1 This test method covers the determination of the mineral-acid-insoluble matter content of copper and iron powders in amounts under 1.0 %. 1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM B294-10 烧结碳化物硬度试验的标准试验方法

Rockwell hardness testing is one of the more important methods used to evaluate cemented carbides. For compositional groups of cemented carbides, hardness is an indication of wear resistance and toughness. Lower hardness grades usually indicate less wear resistance but greater toughness. For a specific grade of cemented carbide, hardness is an indication of the metallurgical quality of the material. In no case is Rockwell hardness testing the only test method to be considered in evaluating cemented carbides.1.1 This test method covers the hardness testing of cemented carbides by use of a Rockwell hardness tester performing tests in the Rockwell HRA scale (regular scale, diamond indenter, 10 kgf (98.07 N) preliminary test force, and 60 kgf (588.4 N) load) in the range of Rockwell 80 HRA and above. Also covered are the procedures for the testing and selection of diamond indenters, the management and traceability of the four levels of standardized test blocks, and the making and calibration of Primary, Secondary, and Working standardized test blocks. 1.2 The Rockwell hardness tester is a convenient and reliable means of measuring the hardness of cemented carbides. A hardness value is obtained easily, but it is subject to considerable error unless certain precautions are observed. 1.3 The latest version of Test Methods E18 shall be followed except where otherwise indicated in this test method. 1.4 The values stated in SI units are to be regarded as standard except that force and length values associated with the Rockwell hardness testers will comply with E18 with force values specified as N (kgf) and indenter length values specified as mm. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
