ASTM B678 – Standard Test Method for Solderability of Metallic-Coated Products Description: Significance and Use 4.1 In order that a sound solder joint be formed simply and quickly in a production operation, the molten solder must readily wet and spread over the surfaces of the products being joined. For this to happen, the surfaces must be …
ASTM B665 – Standard Guide for Metallographic Sample Preparation of Cemented Tungsten Carbides Description: Significance and Use 3.1 This sample preparation procedure may be used to prepare metallographic samples for Guide B657. It does not include all variations of sample preparation. Scope 1.1 This guide prescribes a method for preparing cemented carbides for metallographic examination.
ASTM B659 – Standard Guide for Measuring Thickness of Metallic and Inorganic Coatings Description: Significance and Use 3.1 Most coating specifications specify the thickness of the coating because coating thickness is often an important factor in the performance of the coating in service. 3.2 The methods included in this guide are suitable for acceptance testing and are …
ASTM B657 – Standard Guide for Metallographic Identification of Microstructure in Cemented Carbides Description: Significance and Use 4.1 The microstructure of a cemented carbide affects the material’s mechanical and physical properties. This guide is not intended to be used as a specification for carbide grades. Producers and users may use the microstructural information as a guide …
ASTM B647 – Standard Test Method for Indentation Hardness of Aluminum Alloys by Means of a Webster Hardness Gage Description: Significance and Use 4.1 The Webster hardness gage is portable and therefore useful for in situ determination of the hardness of fabricated parts and individual test specimens for production control purposes. It is not as sensitive …
ASTM B646 – Standard Practice for Fracture Toughness Testing of Aluminum Alloys Description: Significance and Use 5.1 This practice is provided to develop and maintain uniformity in practices for the evaluation of the toughness of aluminum alloys, particularly with regard to supplier qualification, quality assurance, and material release to specifications. 5.2 It is emphasized that the use …
ASTM B645 – Standard Practice for Linear-Elastic Plane-Strain Fracture Toughness Testing of Aluminum Alloys Description: Significance and Use 5.1 This practice for plane-strain fracture toughness testing of aluminum alloys may be used as a supplement to Test Method E399. The application of this practice is primarily intended for quality assurance and material release in cases where valid …
ASTM B610 – Standard Test Method for Measuring Dimensional Changes Associated with Processing Metal Powders Intended for Die Compaction Description: Significance and Use 5.1 Dimensional Change When Compacting and Sintering Metal Powders: 5.1.1 The dimensional change value obtained under specified conditions of compacting and sintering is a material characteristic inherent in the powder. 5.1.2 The test is useful …
ASTM B600 – Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces Description: Abstract This guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys for the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as …
ASTM B578 – Standard Test Method for Microindentation Hardness of Electroplated Coatings Description: Abstract This test method specifies the determination of the microhardness of metallic coatings upon various substrates (electroplated coatings). Measurements shall be made with the Knoop indenter under specified test loads, and the hardness shall be reported as a Knoop hardness number (HK). …
