Scope

Scope: This document specifies the method for stereological measurement of the basic morphological characteristics and distribution of various carbides in powder metallurgy high-speed tool steels based on scanning electron microscopy and image analysis systems, including method principles, testing equipment, testing methods, and inspection reports. This document is applicable to stereological measurement of carbides with an area equivalent diameter of 0.5μm or greater in powder metallurgy high-speed tool steels that have undergone forging and rolling and are delivered in annealed or quenched + tempered conditions. Powder metallurgy high-speed steels with an area equivalent diameter in the range of 0.1μm to 0.5μm, or other states of powder metallurgy high-speed tool steels, may also refer to this document for measurement. This document is not applicable to the measurement of carbides with an area equivalent diameter of 0.1μm or less. This document does not specify any acceptance quality levels for steels or metals.
