Abstract

The paper describes two methods for quantitative characterization of shape of particles or other 3—dimensional elements of materials microstructures. The methods are based on studies of particle sections revealed in a cross-sections of the material. The first method utilizes the concept of radius vector. In the second method particle contours are defined by the angle of the tangent line and the reference direction. An example of application is presented to studies of austenite particles in austenitic-ferritic duplex stainless steels.
