ASTM E975-13<\/h3>\n

Redline Standard: Standard Practice for X-Ray Determination of Retained Austenite in Steel with Near Random Crystallographic Orientation<\/h4>\n
\n

ASTM E975<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1 This practice covers the determination of retained austenite phase in steel using integrated intensities (area under peak above background) of X-ray diffraction peaks using chromium K<\/span>\u03b1<\/span><\/sub> or molybdenum K<\/span>\u03b1<\/span><\/sub> X-radiation.<\/p>\n<\/p><\/div>\n

\n

1.2 The method applies to carbon and alloy steels with near random crystallographic orientations of both ferrite and austenite phases.<\/p>\n<\/p><\/div>\n

\n

1.3 This practice is valid for retained austenite contents from 1\u2009% by volume and above.<\/p>\n<\/p><\/div>\n

\n

1.4 If possible, X-ray diffraction peak interference from other crystalline phases such as carbides should be eliminated from the ferrite and austenite peak intensities.<\/p>\n<\/p><\/div>\n

\n

1.5 Substantial alloy contents in steel cause some change in peak intensities which have not been considered in this method. Application of this method to steels with total alloy contents exceeding 15 weight\u2009% should be done with care. If necessary, the users can calculate the theoretical correction factors to account for changes in volume of the unit cells for austenite and ferrite resulting from variations in chemical composition.<\/p>\n<\/p><\/div>\n

\n

1.6 Units\u2014<\/i>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.<\/p>\n<\/p><\/div>\n

\n

1.7 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.<\/i><\/p>\n<\/p><\/div>\n
