Designation: E1077-14 Standard Test Methods for Estimating the Depth of Decarburization of SteelSpecimens11. Scope1.1 These test methods cover procedures for estimating thedepth of decarburization of steels irrespectih of thecomposition.matrix microstructurc,or section shapc.Thefollowing basic procedures may be used:1.1.1 Screening methods.1.1.2 Microscopical methods.1.1.3 Microindentation hardness methods.1.1.4 Chemical analysis methods.1.2 In case of a dispute, the rigorous quantitative or linealanalysis method (see 7.3.5and 7.3.o vsha with taeyreress-method. These methods can be employed with any crOss-sectional shape.The chemical analytical methods generallyreveal a greater depth of decarburization than the mirascd pw-cal mcthocs but are limited to certain simple shapes and byavailability of equipment.These techniques are generallyreserved for research studies.The microindentation hardnessmethod is suitable for accuratc mcasurementsuotfu araeneastructures with relatively homogenoous microstructures.1.3 The values stated in Sl units are to be regarded asstandard.No other units of measurement are incluaea in thnisstandard.1.4 This stavddard cdoes nor puarport irg afddress. aTs is
