Designation: E1077-14 Standard Test Methods for Estimating the Depth of Decarburization of SteelSpecimens1
1. Scope
1.1 These test methods cover procedures for estimating the
depth of decarburization of steels irrespectih of thecomposition.matrix microstructurc,or section shapc.The
following 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 lineal
analysis 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 generally
reveal a greater depth of decarburization than the mirascd pw-cal mcthocs but are limited to certain simple shapes and by
availability of equipment.These techniques are generallyreserved for research studies.The microindentation hardness
method is suitable for accuratc mcasurementsuotfu araeneastructures with relatively homogenoous microstructures.
1.3 The values stated in Sl units are to be regarded as
standard.No other units of measurement are incluaea in thnisstandard.
