Abstract
This bachelor thesis is focused to degassing in aluminium alloys and mechanism creation of porosity in aluminium alloys. The thesis is divided into two parts. In the first part are described sources of hydrogen and solubility of hydrogen in pure aluminium and in aluminium alloys too. Then the formation bubbles and microshrinkage in casts. The second part is focused to degassing of alloy and hydrogen measurement. For deggasing is typically used Rotary impeler and for hydrogen measurement is used type of device ALU SPEED TESTER.
