ASTM B922-02 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.

BS EN ISO 3252:2000 粉末冶金.词汇

This International Standard gives definitions of terms relating to powder metallurgy. Powder metallurgy is the branch of metallurgy which relates to the manu-facture of metallic powders, or of articles made from such powders with or without the addition of non-metallic powders, by the application of forming and sintering processes. The terms are classified under the following main headings: 1 Powders 2 Forming 3 Sintering 4 Post-sintering treatments 5 Powder metallurgy materials An alphabetical index of the terms defined is also given. NOTE 1 In addition to terms and definitions used in Eng-lish and French, two of the official ISO languages, this Inter-national Standard gives the equivalent terms and definitions in the German language; these are published under the re-sponsibility of the member body for Germany (DIN). How-ever, only the terms and definitions given in the official languages can be considered as ISO terms and definitions. NOTE 2 Additional information on certain of the terms de-fined can be found in the standards given in parentheses at the end of certain definitions. These are listed in the Bibliog-raphy. note:1) In English, the abbreviations PM and P/M are often used for powder metallurgy, as in "PM part", "P/M prod-uct", "PM process".

ASTM B610-00e1 金属粉末样品尺寸变化测量的标准试验方法

The dimensional change obtained under specified conditions of pressing and sintering is a material characteristic inherent in the powder. It is useful to the production, testing, and use of metal powders. The absolute dimensional change may be used to classify powders or differentiate one type or grade from another, to evaluate additions to the powder mix or measure process changes, and to guide in the design of tooling. The comparative dimensional change is mainly used as a quality control test to measure variations between lots of metal powders of the same material composition. Factors known to affect size change are the test specimen process conditions of green density, sinter time, sinter temperature, sinter atmosphere, level of additions to the base metal powder, lubricant type, powder grade, powder type, and powder lot.1.1 This test method covers a procedure for determining the change in dimensions that occurs as a result of sintering a metal powder specimen. The size change referred to is the difference between the die size and the size of the sintered specimen after it has cooled to room temperature, expressed as a percentage. This size change is a basic characteristic of the metal powder. 1.2 The general procedure of measuring a test specimen and die, the calculating he dimensional changes, as described in this test method, also may be used to determine green expansion, heat treat changes, or other dimensional changes of test specimens that result from processing steps.1.3 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents are in parentheses and may be approximate. 1.4 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.
