N1 - Funding Information:
The current study was supported in part by a Grant-in-Aid for Scientific Research (A) (No. 22246097) provided by the Japan Society for the Promotion of Science (JSPS). The synchrotron radiation experiments were performed at the BL20XU of SPring-8 with the approval of the Japan Synchrotron Radiation Research Institute (JASRI) (Proposal No. 2012B1448). The authors wish to thank Dr. Takeuchi and Dr. Suzuki for their assistance with the operation of the X-ray micro-CT at SPring-8, and Dr. Iguchi for help in preparing the Al-TiB2 MMC using the Lanxide process.

N2 - We review in this article the stereological theory of particles and perform stereological analysis of nonspherical TiB2 particles dispersed in solid aluminum. The two-dimensional (2D) particle size distribution (PSD) obtained from a projected area (PSDP) of TiB2 powder and the three-dimensional (3D) PSD based on the volume of particles were independently measured by optical microscopy and the electrical sensing zone method, respectively. The results obtained by the two methods were compared by transforming between them, using a fitted fractal dimension for the particles. The probability mass function of the cross-sectional areas (CSAs) of single nonspherical particles was measured by sectioning 3D reconstructions of particles obtained from a series of X-ray micro-CT images. The transformation from 3D PSD to 2D PSD according to the CSA (PSDC) was performed based on the stereological model. The inverse problem for the transformation from the 2D PSDC to 3D PSD is discussed.
