A Comparison of the. Linear Intercept and. Equivalent Circle. Methods for Grain Size. Measurement in WC/Co. Hardmetals. B Roebuck, C Phatak and I Birks-Agnew. March 2004 The ASTM grain size equation is: n = 2. G-1. (Eq 12) where n is the number of grains per square inch at 100?. Multiplication of n by 15.5 gives the number of grains per square millimeter at 1?, NA. Planimetric Method. The oldest procedure for measuring the grain size of metals is the planimetric method. A circle of known These test methods of determination of average grain size in metallic materials are primarily measuring procedures and, because of their purely geometric basis, are independent of the metal or alloy concerned. In fact, the basic procedures may also be used for the estimation of average grain, crystal, or cell size in Methods for Determining Particle Size. • Microscopy. • Sieving. • Sedimentation techniques. • Optical and electrical sensing zone method. • Laser light scattering techniques. • [Surface area measurement techniques]. 2 Development of a quantitative method for grain size measurement using EBSD. - and Comparison of WC-Co materials produced with different production methods.

Sponsored by A Comparison of Grain Size Measurement Methods. George F. Vander Voort. Consultant – Struers Inc. Abstract. Historically, grain size measurements were first standardized in ASTM E2 in 1917 using the. Jeffries planimetric method. E2 briefly mentioned the Heyn intercept method, but it was not more formally developed 20 Nov 2017 Full-text (PDF) | of a paper presented at Microscopy and Microanalysis 2013 in Indianapolis, Indiana, USA, August 4 – August 8, 2013. 6 Nov 2005 Abstract. Materials physical properties are the results from its microstructures characteristics. So, it is very important to quantify these characteristics in an accurate way. This task can be accomplished by various methods, among them, the visual inspection and the semi-automatic inspection by image Why is particle size important? Which size to measure. 3 Understanding and interpreting particle size distribution calculations. Central values: mean, median, mode. Distribution widths. Technique dependence. Laser diffraction. Dynamic light scattering. Image analysis. 8 Particle size result interpretation: number vs. volume ASTM E112 standard is commonly practiced within the United States for determining the quality Intercept Method vs. Planimetric Method: There are two methods for grains analysis – Intercept and.
