Wytwarzanie i mikrostruktura materiałów warstwowych

Abstract

Due to the growing interest in composite materials and the high demand for such materials, an attempt was made to compare a number of technologies that were used at the Institute of Technology of the Pedagogical University in research on microstructure control. The paper presents an overview of various methods of obtaining metallic layered or semi-layered materials, based on the processing of metals and their alloys in the liquid state and in the solid state. The paper presents the results of microscopic observations made with the use of a metallographic light microscope and a scanning electron microscope. The materials presented in the work belong to such groups of materials as “mokume gane”, superlaminates, melt spun alloys with amorphous/crystalline and amorphous/amorphous microstructure as well as plasma sprayed coatings. The results of these materials indicate that the application of the methods provides real potential for shaping the microstructure that can be potentially useful for many applications.
