A Significant Method for Estimation of the Grain Size of Polycrystalline Materials

Recent advances in friction-stir welding – Process, weldment structure and properties

“…Deformation leads to a large increase in the amount of austenite grain surface and grain edge per unit volume [18,[185][186][187][188][189][190][191]. This would lead to a corresponding large increase in the grain boundary nucleation rate of allotriomorphic ferrite.…”

Macroregion Size Measurements in Bimodal Titanium Forgings Using Two-Dimensional Autocorrelation Method

“…[12] In the literature, various works using the MLI method to measure the size of grains have been proposed. [12][13][14][15][16][17][18][19][20] Willis and Lake [13] used the circle intercept method, and they concluded that the use of different measurement techniques in different laboratories results in significant variations in measured grain diameter and grain size distribution. Furthermore, Karlsson and Gokhale [20] proposed a method for estimating the MLI length of anisotropic structures using vertical sections and trisector methods.…”

“…[1,3,4] The main objective of this article is to unambiguously estimate the width or spacing between these homogeneous regions. To this effect, we employed two different methods: a modified version of the mean linear intercept (MLI) method [12][13][14][15][16][17][18][19][20] and an image analysis method based on spatial autocorrelations.

Kinetics of Normal Grain Growth Depending on the Size Distribution of Small Grains

“…Takayama et al 25) calculated the value of r m in this equation to be expðÀ3' 2 =2Þ, for an array of tetrakaidecahedra.…”
