Heat treatment processes optimalization of ADI with graded Ni content
Klimentová, Jiřina ; Stránský, Karel (referee) ; Pavloušková, Zina (advisor)
This work is focused on segregation processes in the matrix of spheroidal graphite cast iron with different silicon and nickel content during heat treatment. The aim of this work is to trace the redistribution of the elements of interest during homogenization annealing with different dwell time by comparison of the effective distribution coefficients. Comparison of some specific properties and description of structure development of spheroidal graphite cast iron matrix from initial state to the state after ferritization and homogenization annealing is included in this work.

The Structure and Properties of Cast Ceramic EUCOR
Klimentová, Jiřina ; Trunec, Martin (referee) ; Pavloušková, Zina (advisor)
The diploma thesis deals with cast ceramics EUCOR which can be described as three-phase system, composed of corundum, baddelyite and a glassy phase. The study was focused on the analysis of structure and phase composition of the material, together with the assessment of their influence on the basic mechanical characteristics. The techniques of light and scanning electron microscopy were used together with energy-dispersive microanalysis, X-ray diffraction and microhardness measurement.
