ISO 28080:2021 硬质合金. 硬质合金的磨损试验

This document specifies a generic test method to determine the abrasion wear characteristics of hardmetals. The test is appropriate for use in situations where test laboratories have a need to simulate abrasive damage. The procedure includes information which enables the test to be used in a variety of different conditions: a) with counterface wheels of different stiffness (for example steel and rubber); c) different abrasive sizes; b) wet and dry; d) different chemical environments.

Method for determination of sphericity of titanium and titanium alloy powders

ISO 3923-1:2018 金属粉末.表观密度的测定.第1部分:漏斗法

This document specifies the funnel method for the determination of the apparent density of metallic powders under standardized conditions. The method is intended for metallic powders that flow freely through a 2,5 mm diameter orifice. It can, however, be used for powders that flow with difficulty through a 2,5 mm diameter orifice but flow through a 5 mm diameter orifice. Methods for the determination of the apparent density of powders that will not flow through a 5 mm diameter orifice are specified in ISO 3923-2[1].

Metallic powders - Determination of apparent density - Part 1: Funnel method

ASTM B703-17 用阿诺德计测量金属粉末和相关化合物表观密度的标准试验方法

5.1 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. 5.2 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. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM B922-17 物理吸收法测定金属粉末特定表面积的标准试验方法

5.1 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),2 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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3.1 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 (m2/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.

5.1 Both suppliers and users of metals can benefit from knowledge of the skeletal density of these materials. Results of many intermediate and final processing steps are controlled by or related to skeletal density of the metal. In addition, the performance of many sintered or cast metal structures may be predicted from the skeletal density of the starting metal powder, for all or a portion of the finished piece. 1.1 This test method covers determination of skeletal density of metal powders. The test method specifies general procedures that are applicable to many commercial pycnometry instruments. The method provides specific sample outgassing procedures for listed materials. It includes additional general outgassing instructions for other metals. The ideal gas law forms the basis for all calculations. 1.2 This test method does not include all existing procedures appropriate for outgassing metal materials. The included procedures provided acceptable results for samples analyzed during an interlaboratory study. The investigator shall determine the appropriateness of listed procedures. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3.1 State all numerical values in terms of SI units unless specific instrumentation software reports volume or density, or both, using alternative units. In this case, present both reported and equivalent SI units in the final written report. Many instruments report skeletal density as g/cm3 instead of using correct SI units (kg/m3). 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.
