1.1 This International Standard specifies methods of hardness testing of sintered metal materials, excluding hardmetals. 1.2 Procedure 1 determines the apparent hardness of the whole material. Procedure 1 ? applies to sintered metal materials which have either not been subjected to any heat treatment, or which have been heat treated in such a way that the hardness is essentially uniform to a depth of at least 5 mm below the surface, ? applies to the surfaces of sintered metal materials which have been treated in such a way that the hardness is not uniform in the section to a depth of 5 mm below the surface, ? therefore applies to materials in which the hardness is obtained essentially by surface enrichment by carbon, or by carbon and nitrogen (for example by carburizing, carbonitriding, nitrocarburizing or sulfidizing), and ? applies to materials which have been induction hardened. 1.3 Procedure 2 determines the microhardness of the metal phase. Procedure 2 ? applies to all types of sintered metal materials, ? is used, in particular, to determine the hardness profile of case-hardened or carbonitrided materials in accordance with the method described in ISO 4507, and ? also applies to any sintered metallic materials which have been subjected to surface treatments such as electrodeposited plating, chemical coating, chemical vapour deposition (CVD), physical vapour deposition (PVD), laser, ion bombardment, etc. To determine the microhardness of treated surfaces, Procedure 2 applies.

ASTM B934-10 通过微压痕硬度测量铁粉末冶金(P/M)部件有效硬化层深度的标准试验方法

The engineering function of many PM parts may require an exterior portion of the part to have a specified case depth and microindentation hardness.

Both suppliers and users of metals can benefit from knowledge of the skeletal density of these materials.

Standard Practices for Sampling Metal Powders

ASTM B822-10 光散射法测定金属粉末及相关化合物的粒度分布的标准试验方法

Reported particle size measurement is a function of both the actual particle dimension and shape factor as well as the particular physical or chemical properties being measured. Caution is required when comparing data from instruments operating on different physical or chemical parameters or with different particle size measurement ranges. Sample acquisition, handling, and preparation can also affect reported particle size results. It is important to recognize that the results obtained by this test method, or any other method for particle size determination using different physical principles, may disagree. The results are strongly influenced by the physical principles employed by each method of particle size analysis. The results of any particle sizing method should be used only in a relative sense; they should not be regarded as absolute when comparing results obtained by other methods. Light scattering theory has been available for many years for use in the determination of particle size. Several manufacturers of testing equipment now have units based on these principles. Although each type of testing equipment uses the same basic principles for light scattering as a function of particle size, different assumptions pertinent to application of the theory, and different models for converting light measurements to particle size, may lead to different results for each instrument. Therefore, the use of this test method cannot guarantee directly comparable results from different types of instruments. Knowledge of the particle size distribution of metal powders is useful in predicting the powder-processing behavior and ultimate performance of powder metallurgy parts. Particle size distribution is related closely to the flowability, moldability, compressibility, and die-filling characteristics of a powder, as well as to the final structure and properties of finished powder metallurgy (P/M) parts. This test method is useful to both suppliers and users of powders in determining the particle size distributions for product specifications, manufacturing control, development, and research. This test method may be used to obtain data for comparison between lots of the same material or for establishing conformance, as in acceptance testing.1.1 This test method covers the determination of the particle size distribution by light scattering, reported as volume percent, of particulate materials including metals and compounds. 1.2 This test method applies to analyses with both aqueous and nonaqueous dispersions. In addition, analysis can be performed with a gaseous dispersion for materials that are hygroscopic or react with a liquid carrier. 1.3 This test method is applicable to the measurement of particulate materials in the range of 0.4 to 2000 μm, or a subset of that range, as applicable to the particle size distribution being measured. 1.4 The values stated in SI units are to be regarded as the standard. 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.

ASTM B331-10 单轴压缩中金属粉末的可压缩性的标准试验方法

The compressibility value obtained by this test is a measure of a material characteristic of the powder. The test method is useful in research and development projects, as a quality control test in the evaluation and manufacturing control of metal powder production, and as an acceptance test for shipment of metal powder lots. In PM production operations, the test is helpful in determining pressing and tooling requirements for high density parts. Results may be affected by test conditions such as the type amount, and method of lubrication, dwell time during compaction, and die material. The compressibility values may not necessarily agree with results obtained under production conditions.1.1 This laboratory test method covers the determination of the compressibility of metal powders and metal powder mixtures as measured by the extent to which a sample can be densified under controlled conditions in a specified die. 1.2 With the exception of density values, for which the g/cm3 unit is the industry standard, the values stated in inch-pound units are to be regarded as the standard. The values shown in parenthesis are mathematical conversions to SI units that are presented for information only and are not to be considered as 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.
