The objective of the project was the study and analysis of formation of blowholes in Aluminium casting. Solubility of hydrogen gas varies with temperature in the AlSi7 alloy (Aluminium with 7 weight percent Si). Nano particles can act as nucleating agents, so that formation of hydrogen bubbles is induced on so much nuclei, that the size of blowholes does not adversely affect the properties of a component part. Experiments were conducted in this direction and analysis of samples carried out.
