| Abstract: | Considerations on Mircostructural Systematics Many terms of modern engineering materials science have been defined by metal science and metallurgy. Their transmission to other materials as ceramic needs adaption. But also the original content of the terms undergoes timedepending variations according to the nowadays state-of-the-art. This is why the definition and the relation of scientific-technical terms to each other has to be reconsidered again and again. In this context related to microstructure the present paper discusses terms as adhesion, agglomeration, alloys and anisotropy, cohesion, cristallites, directionally solidified eutectics, disordered and duplex microstructures. Engineering materials, grains and grain boundaries are also put into this frame as well as heterogenity, homogenity, incoherence, inhomogenity, in-situ- and interconnected microstructures, isotropy, material and matrix microstructures. Microstructural elements and microstructural levels, microstructural modelling and microstructural parameters are related to microstructure-property-correlations and by multiphased microstructures, ordered microstructures, orientation factors, phases, pores, shape factors, single phase and synthetical microstructures as finally textures and types of microstructures the sequence of terms is completed. What they mean, how they belong together and why microstructure needs them is subject of the constribution. |
