This European Standard establishes a material designation system either by symbols or by numbers for cast iron. The designation system by symbols is applicable to: a) standardized cast iron materials (see 2.1); b) non-standardized cast iron materials (see 2.2). The designation system by numbers is only applicable to standardized cast iron materials (see 2.1). NOTE The use of a designation system by symbols does not necessarily imply that the material is standardized.

ISO/TR 945-2:2011 铸铁的微观结构.第2部分:图像分析的石墨分类

This part of ISO 945 deals with the two-dimensional characterisation of graphite form and size in cast irons. A standard method for determining graphite form by image analysis had not been developed at the time of this report, but several methods are in use in the industry. The purpose of this part of ISO 945 is to give an illustration of what is possible and to suggest ways in which the technique might develop in the future. This part of ISO 945 does not apply to the graphite distribution of grey (lamellar graphite) cast iron as defined in ISO 945-1. This part of ISO 945 describes procedures used to carry out image analysis of graphite form and size and provides a method of comparison to the results obtained using visual analysis techniques. It does not specify any particular mathematical description of the graphite forms but provides a means for comparison. NOTE A mathematical description of graphite form is given in ISO 16112. Other mathematical descriptions of graphite forms and information on technical research are given in the Bibliography.

This European Standard defines the grades and the corresponding requirements for low-alloyed ferritic spheroidal graphite cast irons for elevated temperature applications. These requirements are specified in terms of chemical composition: as given for each of the grades, graphite form and matrix structure: spheroidal graphite in a predominantly ferritic matrix, mechanical properties measured on machined test pieces prepared from cast samples.This European Standard does not cover technical delivery conditions for iron castings, see EN 1559-1 [1] and EN 1559-3 [2].

ASTM E2567-11 使用图像分析测定结核状态和球墨铸铁中球状石墨粒数的标准试验方法

Qualitative measurement of “nodularity” and “nodule count” using visual estimations has been practiced for many years. These methods suffer from poor reproducibility and repeatability. The introduction of computer-aided image analysis enables metallographers to measure and count individual particles of interest in a microstructure with a high degree of precision. This greatly reduces measurement variations compared to visual estimation methods (see, for example, Test Method A247). This method defines a procedure for measuring the number of nodules and the quality of nodularity of spherulitic graphite in a cast iron microstructure. The specimen’s location in a casting or cast test specimen, and the orientation of the plane-of-polish, are governed by product standards. When a product standard is not defined, choose the test location randomly or at specific systematically chosen depths as needed. The plane-of-polish may be parallel or perpendicular to the solidification direction, or chosen at random, depending upon the needs of the study. This test method may be used to determine variations within a given test specimen, within a given location in a casting, between different locations in a casting, or for the same location in different castings over time. Results from this test method may be used to qualify material for shipment in accordance with guidelines agreed upon between purchaser and manufacturer or can be used to monitor process quality or product variations. Measurements are performed using a computer-controlled automatic image analysis system. A minimum number of specimens and a minimum surface area to be evaluated may be defined by producer-purchaser agreement, provided at least 500 particles meeting the minimum size requirements are measured. (See 5.6 for exceptions covering the minimum numbers of particles.) The only exception to the 500-particle minimum assessment requirement is for large castings with a smallest cross-sectional dimension; for example being 15 cm. Graphite particles in such castings are very large typically above Test Method A247 size 4 or 160 µm, and nodule counts are low. The error in measuring a large graphite particle is very low. Therefore, when the mean graphite particle MFD is above Test Method A247 size 4 or 160 µm the number of particles required for a measurement may be reduced to 100 particles. However, the particles measured must still meet the minimum size requirement.1.1 This test method is used to determine the percent nodularity and the nodule count per unit area (that is, number of nodules per mm2) using a light microscopical image of graphite in nodular cast iron. Images generated by other devices, such as a scanning electron microscope, are not specifically addressed, but can be utilized if the system is calibrated in both x and y directions. 1.2 Measurement of secondary or temper carbon in other types of cast iron, for example, malleable cast iron or in graphitic tool steels, is not specifically included in this standard because of the different graphite shapes and sizes inherent to such grades 1.3 This standard deals only with the recommended test method and nothing in it should be construed as defining or establishing limits of acceptability or fitness for pu......
