摘要:

Some parameters used to characterize fictitious features not existing in the real microstructure, such as the total length in a unit volume of the intersection curves made by the interface between the particles of secondary phase with the fictitious grain boundary surface of the matrix phase, are useful for the quantitative characterization of particle–profile contiguity on grain boundary surfaces, and can be determined in an unbiased way from measurements on random planes of polish. It is shown that the contiguity parametersC3Dproposed by Gurland,LV‐type by Cahn&Hilliard andCGBby Liu, all accessible stereologically, have different physical meanings and provide different kinds of quantitative information on particle contiguity. The reversed stereology principle is applicable to contiguity parametersC3DandCGB, since their estimators are comparable. The contiguity analysis carried out for isothermal austenite‐ferrite phase transformation processes occurring in five series of low‐carbon Ti–B or V–Ti–B steels has confirmed the feasibility of the met

摘要:

This paper describes a convenient method for mounting fibres for processing and embedding. Prior to processing, the fibres are mounted across windows in acetate frames. These frames protect the fibres from impact damage during processing, keep the fibres straight, and make alignment of the fibres for sectioning simple and accurate. The frames are produced using purpose‐built devices which are also described in this pape
