Abstract
The statistical random meshing method used for the measurement of microsegr egation in a cast microstructure was simulated using the Monte Carlo method . The standard deviation of measurements, the effect of sample size, the el ectron beam diameter, and the scattering on obtained solute partition coeff icients were analyzed and evaluated. It is found that a sample size between 100 to 200 points can give satisfactory measurement. A method to use the m easured segregation profiles in solid is suggested, Partition coefficients obtained by the statistical random sampling method are found to represent r eal segregation characteristics in the alloys.
