ASTM B886-2003硬质合金磁饱和(Ms)测定用标准试验方法

This test method allows the non-destructive measurement of the magnetic fraction of the binder phase in cemented carbide powder materials and sintered product, and may be used as an indirect measure of the carbon level in the material or product. Measurement of magnetic saturation provides a comparison of the relative fraction of magnetic binder phase that is, cobalt, nickel, or iron, present in the material and can be used for acceptance of product to specification. Measurement of magnetic saturation can be used as a measure of the quality of powder material.1.1 This test method covers the determination of magnetic saturation (Ms) of cemented carbide powder materials and sintered products using magnetic saturation induction test instrumentation.1.2 The values stated in SI units are to be regarded as the 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 B922-2002物理吸收法测定金属粉末特定表面积的标准试验方法

Both suppliers and users of metals can benefit from knowledge of the surface area of these materials. Results of many intermediate and final processing steps are controlled by, or related to, specific surface area of the metal. The performance of many sintered or cast metal structures may be predicted from the specific surface area of the starting metal powder, or all or a portion of the finished piece.1.1 This test method covers determination of surface area of metal powders. The test method specifies general procedures that are applicable to many commercial physical adsorption instruments. The method provides specific sample outgassing procedures for listed materials. It includes additional general outgassing instructions for other metals. The multipoint equation of Brunauer, Emmett and Teller (BET), along with the single point approximation of the BET equation, forms the basis for all calculations.1.2 This test method does not include all existing procedures appropriate for outgassing metallic materials. The procedures included provided acceptable results for samples analyzed during interlaboratory testing. The investigator shall determine the appropriateness of listed procedures.1.3 This method uses SI units as standard. State all numerical values in terms of SI units unless specific instrumentation software reports surface area using alternate units. In this case, present both reported and equivalent SI units in the final written report. Many instruments report surface area as m2/g, instead of using correct SI units (m 2/kg).1.4 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 B925-2003粉末冶金(P/M)试样的生产、制备的标准实施规程

Test specimens are used to determine the engineering properties of P/M materials, for example, tensile strength, ductility, impact energy, etc.; property data that are essential to the successful use of P/M material standards. Processing P/M test specimens under production conditions is the most efficient method by which to obtain reliable P/M material property data since in most cases it is impractical or impossible to cut test bars from sintered parts. The performance characteristics of metal powders, for example, compressibility, green strength and dimensional changes associated with processing are evaluated using P/M test specimens under controlled conditions. The data obtained are important to both metal powder producers and P/M parts manufacturers. P/M test specimens play a significant role in industrial quality assurance programs. They are used to compare properties of a new lot of metal powder with an established lot in an acceptance test and are used in the part manufacturing process to establish and adjust production variables. In those instances where it is required to present equivalent property data for a production lot of P/M parts, standard test specimens compacted from the production powder mix to the same green density can be processed with the production P/M parts and then tested to obtain this information. Material property testing performed for industrial or academic research and development projects uses standard P/M test specimens so the test results obtained can be compared with previous work or published data. Powder metallurgy test specimens may have multiple uses. The dimensions and tolerances given in this standard are nominal in many cases. The user is cautioned to make certain that the dimensions of the test specimen are in agreement with the requirements of the specific test method to be used.1.1 These standard practices cover the specifications for those uniaxially compacted test specimens that are used in ASTM standards, the procedures for producing and preparing these test specimens, and reference the applicable standards.1.2 Basic tool design and engineering information regarding the tooling that is required to compact the test specimens and machining blanks are contained in the annexes.1.3 This standard is intended to be a comprehensive one-source document that can be referenced by ASTM test methods that utilize P/M test specimens and in ASTM P/M material specifications that contain the engineering data obtained from these test specimens.1.4 These practices are not applicable to metal powder test specimens that are produced by other processes such as cold isostatic pressing (CIP), hot isostatic pressing (HIP), powder forging (P/F) or metal injection molding (MIM). They do not pertain to cemented carbide materials.1.5 Detailed information on P/M presses, compacting tooling and sintering furnaces, their design, manufacture and use are not within the scope of these practices.1.6 Test specimen and die cavity dimensions shown in inch-pound units are to be regarded as standard and are applicable to the referenced ASTM test methods and material specifications. Values in SI units are shown in parentheses and result from conversion in accordance with IEEE/ASTM Standard SI-10. They may be approximate and are only for information.1.7 This standard may involve hazardous materials, operations, and equipment. 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.
