Optimization of metallurgical processes in aluminum alloys foundry
Halaška, Jan ; Lána, Ivo (referee) ; Kaňa, Václav (advisor)
Diploma thesis examines the influence of the preparation and metallurgical treatment on the mechanical properties and structure of aluminium alloys Al-Si. The experimental part was carried out at MSR Engines s.r.o. This part describes the current (sodium modification) and newly proposed (strontium modification) state of preparation and metallurgical processing of melt. There is state the course of experimental melting processes, testing of samples, evaluation of tests and observation of the impact of individual modifiers on the structure.

Influence of modification and inoculation on structure and mechanical properties of aluminium alloys
Janošťák, Jan ; Lána, Ivo (referee) ; Roučka, Jaromír (advisor)
This thesis examines the influence of inoculation and modification on the internal structure and properties of aluminium-silicon alloys. The effect of inoculation by titanium and boron and modification by sodium and strontium is investigated in experimental part of the thesis. All these metallurgical interventions in the melt are tested on three types of hypoeutectic Al-Si alloys (AlSi10Mg(a), AlSi8Cu3, AlSi7Mg0,3). The experiment was carried out in cooperation with the foundry of non-ferrous metals, Aluminium Group, a.s. in Sloup.
