Hardenability of aluminium alloys and its experimental determination
 Weiss, Andrej ; Jetela, Václav (referee) ; Klement, Josef (advisor)
The Diploma thesis deals with the verification of Jominy end-quench test when analysis of hardenability of aluminium alloys is considered. The problem was solved experimentally, by developing end-quench curves of selected grades of aluminium alloys. Degree of hardenability of alloy is hardness after complete strengthening heat treatment. Samples of aluminium alloys commonly used for aircraft structures were prepared and then subjected to end-quench tests in various quenchants. On the basis of performed experiments, suitability of Jominy end-quench test for comparison of hardenability of alloys was found. Part of the thesis deals with the creation of equivalent cooling rate diagrams using the developed end-quench curves.

Analysis of response variables of bone samples in a different state of demineralization or deproteinization
 Weiss, Andrej ; Man, Vojtěch (referee) ; Vosynek, Petr (advisor)
The Bachelor thesis deals with the analysis of mechanical properties of cortical bone in a state simulating the decrease of collagenous tissue component. Sensitivity of the selected properties on deproteinization is examined. The problem was solved experimentally. Samples of porcine femur were prepared and then subjected to measurements in physiological and subsequently in deproteinized state. On the basis of performed analyses, the most significant change was found to be in the elastic modulus and damping ratio.
