ASTM B212-99(2006) 自由流动的金属粉末表观密度的标准试验方法

This test method provides a guide for evaluation of the apparent density physical characteristic of powders. The density measured bears a relationship to the mass of powder that will fill a fixed volume press cavity when parts are being made. The degree of correlation between the results of this test and the quality of powders in use will vary with each particular application.1.1 This test method describes a procedure for determining the apparent density of free-flowing metal powders and is suitable for only those powders that will flow unaided through the specified Hall flowmeter funnel.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.

The specific alloy types covered are: Alloy Type Nominal Composition 1 49 % Co, 49 % Fe, 2 % V 2 27 % Co, 0.50 % Cr, balance Fe This specification also covers materials supplied by a pro ducer or converter in the form and physical condition suitable for fabrication into parts that will later be given final heat treatment to achieve the desired magnetic characteristics and where required, mechanical properties. It covers material supplied in form of forging billets, hot-rolled products, cold-finished bars, and strip. The values stated in either customary units (cgs-emu and inch-pound) or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents:therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

ASTM B528-99 金属粉末样品横向断裂强度的标准试验方法

1.1 This test method covers determination of the transverse rupture strength of sintered metal powder test specimens by subjecting them to a uniformly increasing transverse loading under controlled conditions. The term "transverse rupture strength," as used herein, defines the stress, calculated from the flexure formula, required to break a specimen as a simple beam supported near the ends and applying the force midway between the fixed line center of the supports. By varying the composition and preparation of specimens, actual production conditions can be closely simulated. 1.2 The following special tests should be consulted for the specified materials: Test Method B378 and Test Method B406.

1.1 These test methods cover a procedure for evaluating the ability of sintered P/M stainless steel parts/specimens to resist corrosion when immersed in a sodium chloride (NaCl) solution. 1.2 Corrosion resistance is evaluated by one of two methods. In Method 1, the stainless steel parts/specimens are examined periodically and the time to the first appearance of staining or rust is used to indicate the end point. In Method 2, continued exposure to the sodium chloride solution is used to monitor the extent of corrosion as a function of time. 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.

ANSI/ASTM A904:1998 50镍-50铁粉末冶金(P/M)软磁合金规范

This specification covers the magnetic properties of 50 nickel-50 iron parts fabricated by powder metallurgy techniques and is intended for parts that require high magnetic permeability, high electrical resistivity, low coercive force and low hysteresis losses. It differs from the wrought alloy because parts are generally porous (see Specification A753). Porosity can cause some of the magnetic properties to differ from the wrought grade because some magnetic properties are directly proportional to the sintered density. The 50 nickel-50 iron parts shall have a typical chemistry as shown in Table 1. Magnetic properties are affected significantly by the sintering process. Magnetic properties of as-sintered products vary greatly with respect to carbon, nitrogen, oxygen, and sulphur content. The levels of these elements should be agreed upon between the producer and user. Parts made through powder metallurgy techniques, including metal injection molding are generally to configuration of the desired part. If secondary or machining operations are required, which may stress the part, an anneal should be provided to restore magnetic properties to the as-sintered condition, as defined in this specification.

ISO 4491-2:1997 金属粉末 用还原法测定氧含量 第2部分:还原时氢的质量的损失(氢损)

This part of ISO 4491 specifies a method for the determination of the relative loss of mass which a metallic powder undergoes when heated in a stream of pure dry hydrogen under specified conditions. The purpose of this test is to evaluate a chemical powder characteristic which is of importance to the powder metallurgical industry. The test is not intended as a means for the determination of the content of specific elements. (See annex A and ISO 4491 -1.) The test method is applicable to unalloyed, partially alloyed and completely alloyed powders of the metals listed in table 1 (see 6.1). It is not applicable to lubricated powders or to mixtures of metal powders. The results can be influenced by the presence of reducible, oxidizable or volatile metals, metalloids or compounds (see annex A). The results obtained on such powders shall be used with caution and their interpretation shall be subject to agreement between supplier and user. This part of ISO 4491 shall be read in conjunction with ISO 4491-1.
