SCOPE 1.1 Form This specific
6、ation covers an aluminum alloy in the form of die forgings and forging stock. 1.2 Application These forgings have been used typically for parts, requiring strength similar to that of parts machined from AMS4118 bars, but usage is not limited to such applications. Higher strength can be obtained by p
7、recipitation hardening to the T6 temper.2.

38、he convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of this document. An (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions. Change bars and (R) are
39、not used in original publications, nor in documents that contain editorial changes only. 8.2 Hardness 8.2.1 As Solution Heat Treated Should be not lower than 100 HB/10/500 or 106 HB/10/1000, determined in accordance with ASTM E 10. Hardness has been used to verify that product is properly processed,
40、 but an “out-of-range hardness number” is not always indicative of product with “out-of-specification tensile strength”. Further analysis including material composition verification, heat treat process parameter review, and/or tensile property measurement on product with out-of-range hardness may be
41、 necessary.8.2.2 After Precipitation Heat Treatment Should be not lower than 120 HB/10/500 or 125 HB/10/1000, determined in accordance with ASTM E 10, but forgings should not be rejected on the basis of hardness if tensile property requirements are met. 8.3 Terms used in AMS are clarified in ARP1917
42、. 8.4 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and properties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information. 8.5 Purchase documents should specify not less than the following: AMS4134FProduct form and size or part number of product desired Quantity of product desired Standards for acceptance of fluorescent penetrant and/or ultrasonic inspection, when specified (See 3.4.1).
