ASTM E2283-2003 钢和其他微观结构部件中非金属夹杂物的最大值分析标准规程
简介：This practice is used to assess the indigenous inclusions or second-phase constituents in metals using extreme value statistics. It is well known that failures of mechanical components, such as gears and bearings, are often caused by the presence of large nonmetallic oxide inclusions. Failure of a component can often be traced to the presence of a large inclusion. Predictions related to component fatigue life are not possible with the evaluations provided by standards such as Test Methods E 45, Practice E 1122, or Practice E 1245. The use of extreme value statistics has been related to component life and inclusion size distributions by several different investigators (3-8). The purpose of this practice is to create a standardized method of performing this analysis. This practice is not suitable for assessing the exogenous inclusions in steels and other metals because of the unpredictable nature of the distribution of exogenous inclusions. Other methods involving complete inspection such as ultrasonics must be used to locate their presence.1.1 This practice describes a methodology to statistically characterize the distribution of the largest indigenous nonmetallic inclusions in steel specimens based upon quantitative metallographic measurements. The practice is not suitable for assessing exogenous inclusions.1.2 Based upon the statistical analysis, the nonmetallic content of different lots of steels can be compared.1.3 This practice deals only with the recommended test methods and nothing in it should be construed as defining or establishing limits of acceptability.1.4 The measured values are stated in SI units. For measurements obtained from light microscopy, linear feature parameters shall be reported as micrometers, and feature areas shall be reported as micrometers.1.5 The methodology can be extended to other materials and to other microstructural features.1.6 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.

ASTM E1122-1996 用自动图象分析得到JK夹杂物额定值
简介：1.1 This practice covers procedures to perform JK-type inclusion ratings using automatic image analysis in accordance with microscopical methods A and D of Practice E45. 1.2 This practice deals only with the recommended test methods and nothing in it should be construed as defining or establishing limits of acceptability for any grade of steel or other alloy where the method is appropriate. 1.3 The values stated in SI units are to be regarded as the standard. Values in parentheses are conversions and are approximate. 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.
