ABSTRACT

There exists a large amount of difficulty in determining the relationship between microstructure and properties that a material possesses, which is compounded significantly by the inability of two- dimensional characterization to fully capture the shape of individual grains. Three dimensional characterization offers materials scientists the ability to more accurately capture the true shape of grains and grain boundaries, and therefore leads to a clearer depiction of the microstructure of a material. Serial sectioning is an established method for generating microstructural data in three dimensions via the controlled repetition of two dimensional sectioning techniques such as machining, polishing or microtomy. RoboMet.3D is an automated serial sectioning machine used to obtain two dimensional microstructural data for three dimensional reconstructions in a wide range of materials. It presents the opportunity to investigate grains, grain boundaries, precipitates, voids and dendrites in three dimensions. It has numerous advantages such as, significant increase in productivity, consistency and precise control in slice thickness, and less variability between section images, when compared to traditional approaches.
