Using simulation to predict defects in and evaluate properties of die-cast Al-alloy castings
Morávková, Jitka ; Nová, Iva (referee) ; Čech, Jaroslav (advisor)
The purpose of this diploma thesis is comparing the quantity of porosity in die-cast aluminium casting with using simulation. The cast engine blocks were made by high pressure die-casting and a local squeeze casting (LSC) technology. There was also examined the relationship between porosity and mechanical properties of castings. There were evaluated and compared the results of my own measurements with data from previous students theses at the Faculty of Mechanical Engineering BUT. All data were tested by statistical tests. The comparison of simulation results and experimentally measured values was found a good programme-ability to simulate and estimate porosity.

Evaluation of porosity in gravity - cast Al - alloy castings
Staňková, Markéta ; Nová, Iva (referee) ; Čech, Jaroslav (advisor)
Solving of this diploma thesis is evaluation porosity in sequence on mechanical properties from different Al alloys. Castings were made by gravity casting to the iron-mould or gravity casting to the sand. Measurements (mechanical properties, porosity, DAS - dendrite arm spacing, shape factors and sphericity) were statistically analysed and dependencies which were detected were processed to the graphs.

Evaluation of porosity in Al-alloy die-castings
Havel, Jiří ; Nová, Iva (referee) ; Čech, Jaroslav (advisor)
The aim of this diploma thesis is to analyse the porosity of die - cast cast that were made of the alloy AISi9u3 in iron-foundry Skoda Car Mlada Boleslav. The analysis and the sample comparisons are based on my own measurements and are also connected with previous diploma thesis which deals with that issue and was drawn up at Technical University in Brno. All measurements were statistically tested.
